2000-06-10 Federico Mena Quintero * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning, so I needed something to warm my thighs. Running plain infinite loops on your laptop to make it hot is not very much fun. A demo of the gdk-pixbuf scaling functions is way better, and looks prettier, too. * configure.in (AC_OUTPUT): Added the demo Makefile. * Makefile.am (SUBDIRS): Added the demo directory. 2000-06-09 Larry Ewing * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment): setjmp for the png error handler. It seems setting the error handling functions does not avoid the jump, and so not calling setjmp was causing the incremental loader to jump into lala land. (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm not sure this one is actually required but the docs say it must be set for every call to a png_* function. Also changed the comment to reflect the fact that setting the error handlers does _not_ avoid the longjmp. 2000-06-06 Larry Ewing * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): take frame offest into account when trying to calculate the animation bbox. Also set the width to the width not the height. (gdk_pixbuf_loader_animation_done): cycle over the frames to calculate bbox because now we finally have all the offset information for each frame. 2000-06-05 Mathieu Lacage * configure.in: add some gtk parameters to the GDK_PIXBUF_LIB˛S and GDK_PIXBUG_INCLUDEDIR vars. One more fight in my crusade for strange prefix compile... 2000-05-30 Not Zed * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load): Initialise the error handler exit routine to our own. Note this means that every function that accesses the jpeg lib on this object MUST do a setjmp. (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg lib for handling fatal error. (gdk_pixbuf__jpeg_image_load_increment): And here too. So now your applications dont quit if there's a jpeg error! 2000-05-30 Federico Mena Quintero * gdk-pixbuf.spec.in: Include all the loader libraries. Patch from Frank de Lange . 2000-05-09 Darin Adler * gdk-pixbuf/test-gdk-pixbuf.c: Fixed includes to get rid of accidental GNOME dependency. 2000-05-26 Cody Russell * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST 2000-05-22 Federico Mena Quintero * configure.in: Bumped version number to 0.8.0. * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml file was not being distributed. * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS. 2000-05-09 Darin Adler * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb), (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb), (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit formats to 32-bit formats to re-use the high bits of the color values so that white maps to full white. Fri May 5 12:16:32 2000 Owen Taylor * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with detailed information about the structure and algorithms of pixops so people can fix it instead of breaking it. 2000-05-04 Darin Adler * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest), (composite_pixel), (composite_line): * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type): Now that Owen explained the algorithm, I think I implemented it right for the cases where the destination pixbuf is not opaque. The test does seem to confirm it. 2000-05-04 Darin Adler * gdk-pixbuf/.cvsignore: * gdk-pixbuf/Makefile.am: * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel), (load_pixel), (simple_composite_test_one), (simple_composite_test_one_type), (simple_composite_test), (main): Added some tests of composite to highlight problems in the old implementation. These tests run without any user interaction. Just do "make check". * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest), (composite_pixel), (composite_line): Fix composite to do a textbook "A over B" composite. This was clearly the intent, and it was easy to fix the code to do it. (Note to those that read my earlier tries at a patch; this version fixes typos that were present in all my patch attempts. I checked the final version by adding more tests.) 2000-04-22 05:27:43 2000 Owen Taylor * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly offset y coordinate accordining to render_y0. * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero dest_x, dest_y. 2000-04-22 James Henstridge * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main package to the devel package. The only file installed in bin is gdk-pixbuf-config, which belongs in -devel. This should allow having multiple versions of the main gdk-pixbuf package installed. 2000-04-17 Karl Eichwalder * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS). Reported by Jens Finke. 2000-04-14 Tomasz Kłopczko * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly. 2000-04-13 James Henstridge * configure.in: when performing the configure check to see if gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS, rather than the other way round. Also, call AC_MSG_RESULT in the even that dynamic modules were not supported. 2000-04-12 Federico Mena Quintero This comes from an excellent idea by Tim Janik (timj@gtk.org) to hook to the last unref operation. * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New function to set the last unref handler for a pixbuf. (gdk_pixbuf_finalize): New function to actually finalize a pixbuf. It calls the pixbuf's destroy notification function and frees the GdkPixbuf structure itself. (gdk_pixbuf_unref): Use the last unref function of the pixbuf if available. * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields for the last unref handler and its user data. * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use g_new0() to allocate the pixbuf. * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): Fixed the call to gtk_signal_new() for the "frame_done" signal; it was not specifying the `frame' argument. * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_width): Fixed docstring. (gdk_pixbuf_animation_get_height): Likewise. (gdk_pixbuf_animation_get_num_frames): Likewise. (gdk_pixbuf_animation_get_frames): Likewise. * doc/gdk-pixbuf-sections.txt: Updated with the new functions and types. * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace. * doc/tmpl/scaling.sgml: Added the description for GdkInterpType. * doc/tmpl/refcounting.sgml: Updated with the information about the last unref handler. * doc/tmpl/*.sgml: Markup tweaks. * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh, update the libtool version number for libgnomecanvaspixbuf as well. (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned as well, or the old ones won't work with the new stuff. Also, renamed the modules as follows. * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the modules are called "libpixbufloader-.so" instead of "libpixbuf-.so". They needed renaming so that the new loaders won't overwrite the old ones; even with the versioning stuff, the new .so symlink to the .so.1.0.0 would overwrite the old real .so file. 2000-04-12 Paolo Molaro * .cvsignore, src/.cvsignore: shut up cvs. 2000-04-11 Federico Mena Quintero Most of this patch is based on a patch by Havoc Pennington (hp@redhat.com) to make GdkPixbuf's structures opaque and to remove the libart dependency. * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures. (GdkColorspace): New enum that for now only contains GDK_COLORSPACE_RGB. (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy notification function. (GdkInterpType): New num with interpolation types. * *.[ch]: Replace the libart stuff with our own stuff. * pixops/*.[ch]: Likewise. * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private declarations of the GdkPixbuf structures. * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf): Removed function. (gdk_pixbuf_get_format): Constify. (gdk_pixbuf_get_n_channels): Constify. (gdk_pixbuf_get_has_alpha): Constify. (gdk_pixbuf_get_bits_per_sample): Constify. (gdk_pixbuf_get_pixels): Constify. (gdk_pixbuf_get_width): Constify. (gdk_pixbuf_get_height): Constify. (gdk_pixbuf_get_rowstride): Constify. * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy a pixbuf. * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a bits_per_sample argument; currently only 8 bits per sample are supported. * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf): New accessor. (gdk_pixbuf_frame_get_x_offset): New accessor. (gdk_pixbuf_frame_get_y_offset): New accessor. (gdk_pixbuf_frame_get_delay_time): New accessor. (gdk_pixbuf_frame_get_action): New accessor. * gdk-pixbuf/gdk-pixbuf-render.c (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid mask rectangle for pixbufs without an alpha channel, set the *mask_return to NULL. * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify. * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes. * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some preconditions. Maybe we should also check for the colorspace, bits per pixel, and such. (gdk_pixbuf_composite): Likewise. (gdk_pixbuf_composite_color): Likewise. (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we cannot allocate the new pixbuf. (gdk_pixbuf_composite_color_simple): Likewise. * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer have an ArtPixBuf. * gdk-pixbuf/io-bmp.c: Fix includes. * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in an lvalue. * TODO: Populated. * configure.in: Removed checks for libart. * gdk-pixbuf/Makefile.am: Removed references to libart. (noinst_HEADERS): Added gdk-pixbuf-private.h. * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented the version number of the libtool library to indicate that this definitely is not compatible with the old usage. I know you love me. I know you do. * configure.in: Bumped version number to 0.7.0. * README: Updated. * gdk-pixbuf-config.in (--libs): We no longer require libart. * DEPENDS.libgdk_pixbuf: We no longer depend on libart. * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything. 2000-04-06 Jonathan Blandford * gdk-pixbuf/testanimation.c (main): add more info to the testanimation frames. 2000-04-04 Ettore Perazzoli * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_width): New accessor function. (gdk_pixbuf_animation_get_height): New accessor function. (gdk_pixbuf_animation_get_num_frames): New accessor function. (gdk_pixbuf_animation_get_frames): New accessor function. 2000-04-01 Federico Mena Quintero * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount is private information, and the art_pixbuf will go away soon. 2000-03-31 Mark Crichton * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount and gdk_pixbuf_get_artpixbuf accessor functions. 2000-03-29 Federico Mena Quintero * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return gboolean instead of int. 2000-03-29 Radek Doulik * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): same as below * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and height in GdkPixbufAnimation 2000-03-28 Radek Doulik * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for context->frame_done_func and context->anim_done_func to make progressive animation loading work * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done): added priv->pixbuf = NULL as pixbuf is now in frame (and to make gdk_pixbuf_loader_prepare happy) (gdk_pixbuf_loader_frame_done): update animation bbox * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to _GdkPixbufAnimation 2000-03-27 Radek Doulik * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width instead of width and height 2000-03-27 Owen Taylor * gdk-pixbuf/pixops/pixops.c: Fix problem with precendence of >> and & which was keeping composite_color from working with non-gray images. 2000-03-08 Jonathan Blandford * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context. (gdk_pixbuf__gif_image_load_animation): free the context. 2000-03-06 Arjan van de Ven * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a mis-interpretation of the Microsoft documentation. Now it can load .BMP files that are not generated by The Gimp as well. 2000-03-01 Mark Crichton * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally) fix the last auto* build bug (where we have libart, but no gnome-libs) * gdk-pixbuf/Makefile.am: Same. 2000-02-28 Matt Wilson * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g, s/unsigned short/guint16/g, s/unsigned char/guint8/g 2000-02-26 Federico Mena Quintero * README: We don't require libgif/ungif nor libXpm. * NEWS: This was outdated, so updated it. 2000-02-25 Federico Mena Quintero * gdk-pixbuf.m4: Use the correct name for gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing this out. 2000-02-21 Federico Mena Quintero * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0. * doc/compiling.sgml: New appendix documenting the gdk-pixbuf library's particular options to configure.in. * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an entity. * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml. * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment): Fixed typo in prototype name. * configure.in: Changed duplicated AC_MSG_CHECKING message to something more meaningful; now it is "checking whether dynamic modules work". * gdk-pixbuf/pixops/Makefile.am (noinst_PROGRAMS): Do not install the timescale program.

(pixbuf_module_symbol): Wrapper routine that uses the module prefix for the modules to load the information. * configure.in (GDK_PIXBUF_VERSION): New option --disable-modules lets the user specify that gdk-pixbuf should link all image loader code into the library instaed of creating shared library modules. (dynworks): Renamed the automake conditional DYNAMIC_MODULES_WORK to BUILD_DYNAMIC_MODULES. 2000-02-19 Jonathan Blandford * gdk-pixbuf/io-gif.c (new_context): fix case where initial colormap entry is Transparent. 2000-02-19 Owen Taylor * gdk-pixbuf/pixops/pixops.c (scale_pixel): Fix error in scale factors for non-alpha case. 2000-02-14 Mark Crichton * gdk-pixbuf/io-xpm.c (xpm_extract_color): Added check for "g" color type. Imlib/libXpm handle this, but we didn't. 2000-02-14 Darin Adler * gdk-pixbuf/testpixbuf.c: Remove now-unnecessary cast. * .cvsignore: gdk-pixbuf/.cvsignore: More to ignore. 2000-02-14 Elliot Lee * gdk-pixbuf/gdk-pixbuf.h, gdk-pixbuf/gdk-pixbuf-data.c: Make passed-in argument 'const'. 2000-02-04 Michael Meeks * gdk-pixbuf/io-gif.c (struct _GifContext): add x,y_offset. (gif_get_frame_info): put the offsets on the context. (gif_get_lzw): copy them off into the frame. (new_context): no change required; will 0 offsets by default. 2000-01-28 Michael Meeks * gdk-pixbuf/pixops/pixops.c (pixops_process): const + nasty un-consting cast. * gdk-pixbuf/pixops/pixops.h: const. * gdk-pixbuf/gdk-pixbuf-util.c: const. * gdk-pixbuf/gdk-pixbuf-scale.c: const. * gdk-pixbuf/gdk-pixbuf.h: constify lots of things. 2000-02-03 Federico Mena Quintero * gdk-pixbuf/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Added sanity check for width and height being >= 0.

(Pointed out by Tomas Ogren) 2000-01-05 Mark Crichton * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_eat_header_write): Return 0 if gdk_pixbuf_load_loader_module returns FALSE. 2000-01-05 Elliot Lee * gdk-pixbuf/pixops/Makefile.am: Link with -lm (to get 'ceil' function) 2000-01-05 Owen Taylor * doc/Makefile.am doc/gdk-pixbuf-sections.txt doc/gdk-pixbuf.sgml doc/tmpl/scaling.sgml: Added scaling functions into gtk-doc framework. * gdk-pixbuf/gdk-pixbuf-scale.c: Documentation fixes. * gdk-pixbuf/testpixbuf-scale.c (expose_cb): Simplify a bit. * gdk-pixbuf/pixops/pixops.c (pixops_composite_color): Return immediately if scale_x or scale_y is 0. 2000-01-05 Owen Taylor * gdk-pixbuf/pixops/timescale.c: quick fix for initializing arrays in benchmark. 2000-01-05 Jonathan Blandford * gdk-pixbuf/gdk-pixbuf-io.h: Change the order of the update func to make it more compatible with the rest of GTK. Added animation framework for progressive loading. * gdk-pixbuf/io-bmp.c (image_begin_load): Modified to handle new system. * gdk-pixbuf/io-ico.c (image_begin_load): ditto * gdk-pixbuf/io-png.c (image_begin_load): ditto * gdk-pixbuf/io-ras.c (image_begin_load): ditto * gdk-pixbuf/io-jpeg.c (image_begin_load): ditto * gdk-pixbuf/io-pnm.c (image_begin_load): ditto * gdk-pixbuf/io-tiff.c (image_begin_load): ditto * gdk-pixbuf/io-gif.c (image_begin_load): ditto 2000-01-05 Owen Taylor * gdk-pixbuf/pixops/README: Added a README with a TODO and some explainations of the algorithms. * gdk-pixbuf/testpixbuf-scale.c: Set a background pixmap of None to reduce flashing when resizing. 2000-01-05 Owen Taylor * gdk-pixbuf/pixops/: Directory full of pixel data scaling code that will eventually migrate into libart. * configure.in acconfig.h: Add checks for MMX compiler support * gdk-pixbuf/gdk-pixbuf.h gdk-pixbuf/gdk-pixbuf-scale.c: Nice wrapper routines for the code in pixops that operate on pixbufs instead of raw data. * gdk-pixbuf/testpixbuf-scale: Test program for scaling routines. 2000-01-05 Jonathan Blandford * doc/tmpl/animation.sgml: Documentation changes. 2000-01-01 Federico Mena Quintero * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference counting to animations. A web browser may want to share a single copy of an animated GIF if it appears multiple times in a web page, for example. * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the animation functions here. (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL animation if the loader does not support multiframe loading and the single-frame load returned NULL. Check that the filename is not NULL. Updated inline documentation. (gdk_pixbuf_animation_ref): New function. (gdk_pixbuf_animation_unref): New function. Removed gdk_pixbuf_animation_destroy() in favor of reference counting. * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Prettified. Made ref_count assertion more paranoid. Check that the filename is not NULL. (gdk_pixbuf_get_module): Use guchar * and guint for buffer and size, respectively. (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to const char **. * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation with a reference count of 1. * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-animation.c. * doc/tmpl/animation.sgml: Populated. It is still missing a description of the overlay modes. * doc/gdk-pixbuf-sections.txt: Added the animation section. Moved the canvas item section to the end, as it will be moved later to gnome-libs. * doc/gdk-pixbuf.sgml: Added the animation section. * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml. 1999-12-26 Peter Teichman * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker. This closes bug #4676. 1999-12-23 Havoc Pennington * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been set to NULL here (specifically context->animation) was not being set to NULL. use g_new0() to alloc the struct. 1999-12-20 Jonathan Blandford * gdk-pixbuf/io-gif.c: finished work to make animated gifs load correctly. Progressive loading needs some work, but that all needs doing from the gdk-pixbuf-loader end, not here. 1999-12-17 Jonathan Blandford * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file): moved the file here. It seems natural to put this function here, as that's where the gdk_pixbuf_new_from_file function is, but it's still a little convoluted. The source files might be played with in a bit. 1999-12-14 Jonathan Blandford * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_animation): Gets the animation from the loader. 1999-12-16 Federico Mena Quintero * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB before using the GdkPixbuf rendering functions. Thanks to Joe Shaw for pointing this out. 1999-12-13 Federico Mena Quintero * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_class_init): Renamed arguments to width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for consistency with the new canvas. (PixbufPrivate): Do the same renaming in the structure fields, for consistency. * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names. 1999-12-12 Federico Mena Quintero * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a conditional to see whether to link $(GNOME_LIBS) or not. 1999-12-10 Jonathan Blandford * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API. * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable): make a warning go away. * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations. * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for animations. 1999-12-09 Michael Zucchi * gdk-pixbuf/gdk-pixbuf.h: Enable gdk_pixbuf_get_from_drawable() api call. * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable): Filled in body of function. (rgbconvert): Added GdkColormap parameter, and to all conversion functions also. (convert_real_slow): New function - should convert ANY visual/data format properly, but it aint fast. Used as a fallback when an optimised routine wont match. (rgbconvert): Do very specific tests on the data format to verify properly if the optimised version will do, otherwise use the fallback function for all other data formats. * gdk-pixbuf/Makefile.am: Re-enabled building of textpixbuf-drawable. * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use gdk_pixbuf_get_from_drawable(). 1999-12-08 Arjan van de Ven * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red bug on two occasions. * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu function to the generic glib one. 1999-12-08 Federico Mena Quintero * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes. (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity checks and API definition. The body needs filling in and it needs to do the Right Thing(tm) for pixmaps plus the given colormap and windows and their own colormaps. * gdk-pixbuf/gdk-pixbuf.h: Added prototype for gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h. * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources. * doc/tmpl/from-drawables.sgml: Populated. * doc/gdk-pixbuf.sgml: Added the from-drawables section. * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml. * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs from drawables. 1999-12-07 Federico Mena Quintero * doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about reference counting for GdkPixbuf structures. 1999-12-07 Martin Baulig * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally include $(GNOME_LIBS) here. 1999-12-05 Arjan van de Ven Added missing "include " to: * gdk-pixbuf/io-ras.c * gdk-pixbuf/io-bmp.c * gdk-pixbuf/io-ico.c 1999-12-06 Federico Mena Quintero * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to fix an initializer. 1999-12-05 Federico Mena Quintero * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back $(GNOME_LIBS). This must compile outside of gnome-libs. If you want, send me a patch to do the conditional stuff properly. Otherwise, please read the GNOME Programming Guidelines, especially the "CVS policies" section. 1999-12-05 Jaka Mocnik * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD. 1999-12-05 Arjan van de Ven * gdk-pixbuf/io-ico.c: Bug in palet-size calculation fixed 1999-12-04 Arjan van de Ven * gdk-pixbuf/io-bmp.c: Major cleanup, added support for 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp. * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons, ran through lclint. * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files (Windows Cursor files). These are identical to .ICO files, except for the signature and 2 extra fields for the hotspot. 1999-12-03 Federico Mena Quintero * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg): Removed unused variable `item'. 1999-12-03 Jonathan Blandford * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to explain this function better. 1999-12-02 Federico Mena Quintero Source files moved from src/ to gdk-pixbuf/, to be consistent with other libraries. * doc/Makefile.am: Modified for the new source directory. * configure.in: Likewise. * Makefile.am: Likewise. * autogen.sh: Likewise. * gdk-pixbuf/Makefile.am: Likewise. 1999-12-02 Federico Mena Quintero * src/testpixbuf.c: #include , and fix includes. * src/testpixbuf-drawable.c: #include , and fix includes. * src/io-xpm.c: Fix includes. * src/io-tiff.c: Fix includes. * src/io-ras.c: Fix includes, and do not include more stuff than needed. * src/io-pnm.c: Fix inlcudes, and do not include more stuff than needed. * src/io-png.c: Fix includes. * src/io-ico.c: Fix includes, and do not include more stuff than needed. * src/io-gif.c: Fix includes, and do not include more stuff than needed. * src/io-bmp.c: Fix includes, and do not include more stuff than needed. * src/gnome-canvas-pixbuf.c: Fix includes. * src/gdk-pixbuf.c: Fix includes. * src/gdk-pixbuf-util.c: Fix includes. * src/gdk-pixbuf-render.c: Fix includes. * src/gdk-pixbuf-io.h: Fix includes. * src/gdk-pixbuf-drawable.c: Fix includes. * src/gdk-pixbuf-drawable.h: Use angle brackets for the gdk-pixbuf include files. * src/gdk-pixbuf-data.c: Fix includes. * src/gdk-pixbuf-loader.c: #include * src/gdk-pixbuf-loader.h: Use angle brackets for the gdk-pixbuf include files. * src/Makefile.am: Commented out the gdk-pixbuf-drawable stuff, since it is not finished. * src/gdk-pixbuf.h: Removed unused transformation prototypes. * src/gdk-pixbuf-util.c: New file with utility and convenience functions for pixbufs. * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c. * doc/gdk-pixbuf-sections.txt: Added section for utility functions. * doc/Makefile.am (tmpl_sources): Added tmpl/util.sgml. * doc/gdk-pixbuf.sgml: Added the utilities section. * doc/tmpl/util.sgml: Documentation for the utility functions. 1999-11-29 Owen Taylor * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha): Keep the mask around until after we draw ... since the GC changes aren't flushed to the X server until we draw, destroying it before that may result in BadPixmap errors. 1999-11-30 Havoc Pennington * configure.in: Add AM_CONDITIONAL for inside gnome-libs * src/Makefile.am: conditionalize GnomeCanvasPixbuf 1999-11-29 Federico Mena Quintero * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This should be made conditional, not blindly commented out. 1999-11-29 Jonathan Blandford * src/Makefile.am (ICO_LIB): Added another loader from Arjan to handle .ico files. Cool. 1999-11-24 Jonathan Blandford * src/io-bmp.c (OneLine24): new patch from Arjan to handle compressed bmps. 1999-11-24 James Henstridge * configure.in (AC_OUTPUT): altered hack to place the symlink in the top builddir rather than src. This still builds fine, and does not get gtk-doc into an infinite loop when trying to find all the source files. 1999-11-23 Jonathan Blandford * Removed #PRAGMA } from headers. Also, make compile if you don't have it installed, already. 1999-11-22 Federico Mena Quintero * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the temporary buffer to the size of the interesction of the bounding box and the expose area, not the whole expose area. This speeds up things a lot. * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do not paint black on the mask, since we already cleared it in a single gdk_draw_rectangle() operation. 1999-11-22 Raja R Harinath * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir. 1999-11-22 Havoc Pennington * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher adds all -lgdk-pixbuf and all other dependencies to LIBADD variables for loadable modules. Necessary for a Java dynamic loading thing to be able to figure it out. 1999-11-22 Havoc Pennington * src/io-png.c (image_load_increment): Call the update_area callback depending on the number of rows loaded in this increment. * src/testpixbuf.c (main): slow down the progressive load demo 1999-11-16 Havoc Pennington * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include 1999-11-22 Jonathan Blandford * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work for srcdir != buildir != . Beats me why; I can't figure it out. AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly. 1999-11-21 Jonathan Blandford * src/gdk-pixbuf-io.c: added io-bmp from Arjan 1999-11-20 Michael Zucchi * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Rework/reorder of the code. Each case has been separated into another function; its big but it should be quick. gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with opaque alpha information. Not all depths/formats have been tested, but 8, 15/16 and 24 (alinged 32) should work ok. 1999-11-17 Larry Ewing * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds): implement the bounds method correctly. (compute_viewport_affine): compute the affine need to fit the image within the viewport given by the args. (compute_render_affine): call compute_viewport_affine. 1999-11-16 Havoc Pennington * src/gdk-pixbuf-drawable.h: Use includes from the current directory, not the system directory. Mon Nov 15 17:18:28 1999 George Lebl * src/testpixbuf-drawable.c: use includes from the current directory rather then from the system include directory as gdk-pixbuf includes are not yet installed when this is compiled. 1999-11-13 Cody Russell * src/testpixbuf-drawable.c: Added a test program for drawable code. * src/Makefile.am: Build testpixbuf-drawable. 1999-11-12 Cody Russell * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes. 1999-11-10 Federico Mena Quintero * doc/tmpl/gdk-pixbuf-loader.sgml: Populated. * doc/gdk-pixbuf.signals: Put in the real names of signal arguments. * src/gdk-pixbuf-loader.c: Improved documentation comments. 1999-11-10 Jonathan Blandford * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the closed signal. * src/io-ras.c (OneLineMapped_file): Now can handle indexing correctly. Patch from Arjan to do so. 1999-11-10 Michael Fulbright * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM files. * src/testpixbuf.c: Added final queued draw when done loading image. 1999-11-10 Jonathan Blandford * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious print statements. 1999-11-10 Federico Mena Quintero * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added documentation. 1999-11-09 Federico Mena Quintero * src/io-png.c: Fixed some incompatible pointer initializations. * src/io-jpeg.c (image_load_increment): Remove unused variable. 1999-11-09 Michael Fulbright * src/testpixbuf.c: Fixed it to use timeout to read from file for progressive loading. Set TBF_KBPS=n, where n is the number of kilobytes/second to simulate in downloading. n has to be an integer. * src/io-jpeg.c: Slight cosmetic cleanup. * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII PBM loading has a similar problem and will address tomorrow. 1999-11-09 Havoc Pennington * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the gdk-pixbuf-drawable stuff. 1999-11-09 Federico Mena Quintero * configure.in: Bumped version number to 0.4. 1999-11-09 Michael Fulbright * src/io-pnm.c : Finished progressive PNM loading code. Should handle all types of PNM files now. * src/io-jpeg.c (image_load_increment): Figured out problem with loading Progressive JPEG's progressively (say that 10 times fast). Currently for Progressive JPEG's the entire image is loaded before it is displayed. libjpeg supports a fancier mechanism which I may implement later. With these changes all JPEG formats appear to load properly for me. 1999-11-08 Jonathan Blandford * src/io-ras.c (image_load_increment): Final patch from Arjan. Seems to do progressive loading. 1999-11-08 Michael Fulbright * src/io-pnm.c image_load (): Fixed so we do not create a separate pixel buffer when reading in image - we reuse the pixel data in the GdkPixbuf structure instead. 1999-11-08 Michael Fulbright * src/io-pnm.c pnm_read_ascii_scanline (): Added support for ASCII PNM files. Note I haven't tested loaded ASCII PBM files because I can't seem to find a utility to convert into this format. Next is to add progressive loading support for the PNM format. 1999-11-07 Federico Mena Quintero * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation of the width, height, x, and y setting and pixels arguments. 1999-11-05 Jonathan Blandford * src/io-ras.c (image_load): third patch. Now it seems to load. * src/gdk-pixbuf-io.c: second patch Arjan van de Ven to autodetect/load the sunras files. * src/io-ras.c (image_load): new file from Arjan van de Ven to begin the ras loader. 1999-11-05 Federico Mena Quintero * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is for internal use only. * doc/gdk-pixbuf.sgml: Likewise. * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs. 1999-11-05 Michael Fulbright * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM files from a file. Next step is support for ASCII files, and then incremental loading. 1999-11-04 Federico Mena Quintero * Makefile.am: Added doc to SUBDIRS. 1999-11-04 Michael Fulbright * src/io-jpeg.c: Prettied up code slightly. * src/io-pnm.c: Start of pnm loader (from file and progressively). Doesn't do much yet (will finish tomorrow). * src/gdk-pixbuf-io.c: Added pnm to structure of known types. 1999-11-04 Federico Mena Quintero * doc/tmpl/rendering.sgml: Populated. * doc/Makefile.am: Added the template files. 1999-11-04 Havoc Pennington * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In docs, explain what a dither offset is for. (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use this function vs. gdk_pixbuf_render_to_drawable(). 1999-11-04 Havoc Pennington * configure.in: Use libart-config correctly; find gnome-config separately. Fix GNOME_LIBS to be correct in "no gnome installed yet" case. * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded library list. Patch untested in the inside-gnome-libs case, I need to commit then check out to the gnome-libs I'm using. 1999-11-04 Michael Fulbright * src/io-jpeg.c (image_begin_load): Add update_func callback. * src/io-jpeg.c (image_load_increment): Call updated callback when new graphic data decoded. 1999-11-04 Jonathan Blandford * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_update): handle the actual update. * src/io-png.c (image_begin_load): add a update_func callback. * src/io-gif.c (image_begin_load): add a update_func callback. (gif_get_lzw): added the update_func ability * src/io-tiff.c (image_begin_load): add a update_func callback. 1999-11-04 Federico Mena Quintero * doc/tmpl/gdk-pixbuf.sgml: Populated. * doc/tmpl/refcounting.sgml: Populated. * doc/tmpl/file-loading.sgml: Populated. * src/gdk-pixbuf.c: Added documentation comments. * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Added documentation comments. * doc/: Finished integrating the documentation framework. 1999-11-03 Federico Mena Quintero * configure.in: Removed libgif stuff now that we do not depend on it. Added the necessary cruft for gtk-doc. * src/Makefile.am: Unconditionally build the GIF loader. 1999-11-03 Jonathan Blandford * src/io-gif.c (gif_read): renamed ReadOK to gif_read. Added a lot of comments to the file. * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on lib*gif!!!! 1999-11-03 Michael Fulbright * src/io-jpeg.c (image_load_increment): Further removal of bugginess in local buffering code. Handles grayscale jpegs correctly now. * src/io-jpeg.c (image_load_stop): Was freeing local context for jpeg library before calling jpeg_decompres_finish (). 1999-11-03 Jonathan Blandford * src/io-gif.c (image_load_increment): now handle arbitrary buffer sizes. (gif_get_lzw): set the transparency to the right val. 1999-11-03 Federico Mena Quintero * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init): Initiailize the x and y fields. (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction. (PixbufPrivate): Renamed need_size_update to need_xform_update. (recompute_bounding_box): Do not use temporary values. 1999-11-03 Jonathan Blandford * src/io-gif.c (set_gif_lzw_clear_code): new state. Fixes un-compressed gifs. * src/gnome-canvas-pixbuf.c (recompute_bounding_box): remove unneeded x,y,h,w vars. 1999-11-03 Larry Ewing * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust render_affine calculation for x,y offsets. (gnome_canvas_pixbuf_set_arg): add x,y args. (gnome_canvas_pixbuf_get_arg): add x,y args. (recompute_bounding_box): simply code using ArtDrect and the render_affine. Removed compute_xform_vectors as it was no longer needed. 1999-11-03 Federico Mena Quintero * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a doofus. Return a distance, not a boolean, for opaque images. * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper rounding of bounding box coordinates. (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method. (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value. 1999-11-03 Jonathan Blandford * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g 1999-11-03 Michael Fulbright * src/io-jpg.c (image_load_increment): Fixed code which moved buffer around as new data comes in to work properly. JPEG progressive loading should be working now except for grayscale JPEG's, which I will look into next. 1999-11-03 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour. Also put dot printing back in. 1999-11-03 * src/io-gif.c (gif_get_extension): Read 'til the next empty block correctly, now. 1999-11-02 Cody Russell * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL if part of the requested image is offscreen, rather than clipping the image. 1999-11-02 Jonathan Blandford * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas for interlacing and progressive loading. 1999-11-02 Cody Russell * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new(). 1999-11-02 Jonathan Blandford * src/io-gif.c (gif_main_loop): Now progressive gif loading works! It's a little slow though. )-: 1999-11-02 Elliot Lee * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the write/load_increment operations const-correct. 1999-11-02 Federico Mena Quintero * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): Implemented the ::point() method. We do a simple containment test instead of a full distance calculation since the canvas is going to change to that scheme, anyways. 1999-11-02 Elliot Lee * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks that are read from the input file. 1999-11-02 Larry Ewing * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa render function. (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render to class. 1999-11-02 Federico Mena Quintero * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the affine computation code from ::draw() to here, since it is needed by ::point() as well. 1999-11-02 Elliot Lee * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into three functions, and eliminate duplication of code from write() and close(). Also fix bug where the 128-byte header was being written twice. 1999-11-01 Federico Mena Quintero * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed bounding box computation. 1999-11-01 Federico Mena Quintero * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item. Drawing affines seem to work. Bounding box is fubared. ::point() is not implemented. This is a work in progress. * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of sources. * configure.in: Sigh. We need to link in libgnomeui for the canvas stuff. This mess will disappear when gdk-pixbuf gets folded into gnome-libs. 1999-10-30 Jonathan Blandford * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of the right size, at a minimum, even if the image is squished and the wrong color. (ReadImage): lets get the offset right. This will let transparent gifs work. 1999-10-29 Michael Fulbright * src/io-jpeg.c: image_load_increment(): Fixed bug when image width was not a multiple of 4 - always use the gdk_pixbuf rowstride to increment pointers! 1999-10-29 Michael Fulbright * src/io-jpeg.c: Added first cut at progressive jpeg loading. Currently does not handle either progressive jpeg files (jpeg files with multiple scans at different quality settings), but I plan on adding this support soon. These are fairly rare in my experience, so it shouldn't slow people down too much. Grayscale jpegs also don't work but that should be easy to fix. 1999-10-29 Michael Fulbright * src/testpixbuf.c: Added title to windows so you can identify progressive and file windows. 1999-10-29 Michael Fulbright * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually load the image handler when we determine the image type. * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the previously static function load_image_handler () to a public function gdk_pixbuf_load_module (). It is needed in gdk-pixbuf-loader.c to load image handler modules. This function is different from gdk_pixbuf_get_module (), which only returns a reference to the required handler, because it actually loads the handler into memory. Both actions should possibly be combined in a convenience function since one w/o the other doesn't seem to make much sense. 1999-10-28 Jonathan Blandford * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a 0 length buffer. 1999-10-28 Federico Mena Quintero * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New function to render a portion of a pixbuf to a drawable. Ignores alpha information and takes in a GC. (gdk_pixbuf_render_to_drawable_alpha): New function to render a portion of a pixbuf to a drawable. It automatically creates a GC and a clipping mask for alpha pixbufs. 1999-10-28 Jonathan Blandford * src/gdk-pixbuf.h: turned convenience macros into convenience functions so some error checking could be added. * src/io-tiff.c (image_load_increment): started work on the tiff non-incremental loader. (image_begin_load): Finished the incremental loader. * src/io-gif.c (image_load_increment): started work on the gif incremental loader. * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule. 1999-10-27 Federico Mena Quintero * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New function to threshold a pixbuf's alpha channel into a bitmap. * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will contemplate future extensions to ArtPixBuf's formats. * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new(). * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience macros to fetch the ArtPixBuf's fields. 1999-10-27 Havoc Pennington * src/testpixbuf.c (main): Display the progressive load * src/io-png.c (setup_png_transformations): Break transformation code into separate function (png_info_callback): Use setup_png_transformations 1999-10-27 Havoc Pennington * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check properly whether the XPM module has already been loaded (gdk_pixbuf_new_from_file): Check properly if loader module was already loaded (was checking if load symbol was present in order to decide whether to re-load; should check module != NULL, then load != NULL) (image_handler_load): Check in present working directory, makes it easier to debug for now (file_formats): This array initializer was seriously on crack, was assigning a function pointer to a GModule* * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader* 1999-10-27 Havoc Pennington * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_finalize): Fix typo that prevented compilation (gdk_pixbuf_loader_destroy): ditto 1999-10-27 Federico Mena Quintero * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a GdkPixbufLoader, not a GtkObject. (gtk_marshal_NONE__INT_INT_INT_INT): Made static. (gdk_pixbuf_loader_get_type): Documented. (gdk_pixbuf_loader_class_init): Initialize the parent class correctly. (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent class destroy function. (gdk_pixbuf_loader_new): Documented. (gdk_pixbuf_loader_finalize): Call the parent class finalize function. (gdk_pixbuf_loader_write): Use size_t for count. 1999-10-27 Michael Fulbright * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed logic so we only try to close loader if it wasn't previously closed. 1999-10-27 Michael Fulbright * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of pixbuf_loader properly initialized. * src/testpixbuf.c: Made sure we cleanup pixbuf_loader properly when done. 1999-10-26 Jonathan Blandford * src/gdk-pixbuf-io.c (image_handler_load): load the vtable fully. * src/gdk-pixbuf-loader.c: Finished initial cut at the object. 1999-10-26 Havoc Pennington * src/gdk-pixbuf-loader.h: fix signals * src/gdk-pixbuf-io.h: add new vtable fields 1999-10-26 Jonathan Blandford * src/gdk-pixbuf-loader.h: New Class. Beginning of progrssive loading. 1999-10-25 Federico Mena Quintero * configure.in (CFLAGS): Patch from Uwe Koloska to fix a stupid typo of mine. 1999-10-22 Havoc Pennington * src/io-xpm.c (mem_buffer): Clean up stupid increment-inside-array-dereference thing * src/testpixbuf.c: Add XPM data tests. * src/io-xpm.c: Make the XPM data buffer const, fix const correctness throughout the code. 1999-10-22 Havoc Pennington * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data() 1999-10-22 Havoc Pennington * src/io-xpm.c (image_load_xpm_data): Export this symbol for loading an XPM from memory. * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): New function, loads pixbuf from xpm data (image_handler_load): Add g_return_if_fail() to ensure the same module isn't loaded twice. Add g_module_symbol() to scan for XPM loader function. 1999-10-22 Federico Mena Quintero * src/io-png.c (image_load): Patch from Kristian Hogsberg Kristensen to avoid allocating extra row buffers; the rows can be read in directly into the main pixel buffer. 1999-10-20 Federico Mena Quintero * src/gdk-pixbuf-io.c (image_handler_load): Free path. 1999-10-20 Federico Mena Quintero * configure.in: Bumped version number to 0.3. * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool version number for the library. 1999-10-20 Federico Mena Quintero * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now all memory management of the buffer is done by libart. * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here. Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate. * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in terms of the libart functions. Removed the old code. * src/gdk-pixbuf-io.c (image_handler_load): Removed the save symbols. Saving will not be implemented in GdkPixbuf. * src/io-gif.c: Removed the saving stub. (image_load): Fixed memory management to fail gracefully if we run out of memory while loading the image. Close the gif file when we are done. This still needs more error handling for the DGif functions. * src/io-jpeg.c (image_load): Some robustness fixes. * src/io-png.c: Removed the saving stuff. (image_load): Some memory management fixes. * src/io-tiff.c (image_load): Ditto. * src/io-xpm.c (pixbuf_create_from_xpm): Ditto. 1999-10-18 Havoc Pennington * subautogen.sh: New name for macros/autogen.sh * autogen.sh: use subautogen.sh 1999-10-18 Federico Mena Quintero * src/*: Reindented to use the GNOME Indentation. Renamed GdkPixBuf to GdkPixbuf, for consistency with the function names (and it is also easier to type) :-) 1999-10-18 Havoc Pennington * configure.in: Use AM_PATH_GLIB instead of glib-config directly * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS 1999-10-18 Havoc Pennington * Makefile.am (SUBDIRS): Remove "macros" * configure.in: Don't use GNOME_INIT, handle case where we are inside gnome-libs. AM_PATH_GTK for the GIF test * src/Makefile.am: Change flags to work without libgnomeui, comment out testpixbuf for now 1999-10-18 Federico Mena Quintero * configure.in: Use $GTK_LIBS as the extra libs when checking for libgif/libungif, as they need the X libraries. Fixes bug #2472. 1999-10-10 Cody Russell * src/gdk-pixbuf-drawable.c: core function now determines whether the requested geometry is on screen or not, and if some is not then the request is clamped to geometry that is on the screen. Changed 'pixbuf' to 'art_pixbuf' in core function. 1999-10-08 Michael Fulbright * src/gdk-pixbuf-data.c: Added to load rgb data from const data. * src/testpifbuf: Changed test program to display cdrom from rgb data if no filename given to test program. 1999-10-07 Cody Russell * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed them, but I wrote them). * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now compile. * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS. * src/gdk-pixbuf-drawable.c: Added #include "gdk-pixbuf-drawable.h" to fix compilation. * src/gdk-pixbuf-drawable.[ch]: Changed functions to return GdkPixBuf* instead of ArtPixBuf*. 1999-09-22 Michael Meeks * src/gdk-pixbuf.c (gdk_pixbuf_new): created. (gdk_pixbuf_scale): use gdk_pixbuf_new + return a new scaled image. * src/gdk-pixbuf.h (struct _GdkPixBuf): Re-organise struct, + add GdkPixBufUnrefFunc + gdk_pixbuf_new. * src/io-jpeg.c (image_load): clean to use gdk_pixbuf_new. * src/io-xpm.c (_pixbuf_create_from_xpm): ditto. * src/io-tiff.c (image_load): ditto + fix leak * src/io-png.c (image_load): ditto + add more exit points; monitor.png crashes this module ( add warning :-) * src/io-bmp.c (image_load): ditto. * src/io-gif.c (image_load): ditto. 1999-09-18 Michael Meeks * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so it doesn't crash scaling with alpha. 1999-09-17 Federico Mena Quintero * src/io-bmp.c (image_load): Set the initial ref_count to 1. * src/io-gif.c (image_load): Likewise. * src/io-jpeg.c (image_load): Likewise. * src/io-png.c (image_load): Likewise. * src/io-tiff.c (image_load): Likewise. * src/io-xpm.c (_pixbuf_create_from_xpm): Likewise. * src/gdk-pixbuf-io.c (gdk_pixbuf_load_image): Added an assertion for the ref_count to be != 0. * src/gdk-pixbuf.c (gdk_pixbuf_ref): Be more paranoid with sanity checking. (gdk_pixbuf_unref): Fix incorrect sanity check and comparison. 1999-08-09 Federico Mena Quintero * src/io-png.c (image_save): Fixed compiler warnings. Fixed write to unallocated memory (row_ptr), and fixed its type as well. Take into account the ArtPixbuf's rowstride when assigning the row pointers. * src/gdk-pixbuf.c: Fixup includes. * src/gdk-pixbuf-io.c: Likewise. Sat Jul 31 19:19:47 CEST 1999 * src/gdk-pixbuf-io.c: * src/io-png.c: Fixed two obvious C syntax bugs 1999-07-29 Mark Crichton * src/io-png.c (image_save): Added PNG saving function * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's image_save(GdkPixBuf *p, FILE *f, ...) 1999-07-26 Michael Zucchi * src/Makefile.am (*_LIB): Only build the relevant loaders which require extra libraries if we actually have those libraries. 1999-07-23 Richard Hestilow * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes * gdk_pixbufConf.sh.in: Added for gnome-config * Makefile.am: * configure.in: Modified to generate gdk_pixbufConf.sh 1999-07-20 Mark Crichton * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox calculation needs to be done. 1999-07-18 Larry Ewing * src/io-xpm.c: * src/io-gif.c: * src/io-png.c: * src/io-jpeg.c: Fix a few memory leaks in the, most of them in error cases but one or two in the common case. There are probably a few small ones left. 1999-07-18 Mark Crichton * configure.in: removed version.h. * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability improvements. 1999-07-17 Mark Crichton * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code. (gdk_pixbuf_rotate): Added pixbuf rotation code. (gdk_pixbuf_scale): Changed // comments to /* */ * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy function to header. 1999-07-16 Larry Ewing * src/testpixbuf.c (expose_func): reverted the expose everything changes, I'm not sure why these went in. (config_func): bring this up to date with the new pixbuf_scale semantics. * src/gdk-pixbuf-io.c: added a couple of warnings to the module loading code so that poeple can diagnose problems better. * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it no longer allocates a new pixbuf, which make things nicer for the rest of the code. Unfortunately there is still a problem with scaling rgba images. 1999-07-16 Mark Crichton * src/testpixbuf.c (config_func): ConfigureEvent handler. This calls gdk_pixbuf_scale. However, something is not working. N.B.: current pixmap is now stored in user_data with a key of "pixmap" * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function. Something is still borked, however. 1999-07-15 Larry Ewing * src/io-jpeg.c (image_load): add raph@gimp.org's fix to the jpeg indexing routine * src/testpixbuf.c (main): fix up the file routines a little so that you can load multiple files given the file names 1999-07-14 Larry Ewing * src/testpixbuf.c (expose_func): added an almost proper expose handler for testpixbuf 1999-07-13 Mark Crichton * configure.in: Fixed GIF check. Replaced " with ' * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale 1999-07-13 Mark Crichton * configure.in: I am a bonehead. Added gif-lib check.
