Most of this patch is based on a patch by Havoc Pennington (hp@redhat.com) 2000-04-11 Federico Mena Quintero <federico@helixcode.com> 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.

Add built marshaller files to support GdkPixbufLoader signals 2001-01-22 Havoc Pennington <hp@redhat.com> * Makefile.am: Add built marshaller files to support GdkPixbufLoader signals * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in module location, rather than acting as a fallback, because we are using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it. * gdk-pixbuf.h: include gdk-pixbuf-loader.h * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here from gtk, and add error to close(), because stop_load may do parsing of the image. * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file * io-*.c: make individual operations static, and add fill_vtable functions which are exported. Fix the collection of type warnings that surfaced, including a number of functions that didn't properly take a GError and some that weren't const-correct. Involved adding error handling for a few loaders. * gdk-pixbuf-io.h: Add error reporting to stop_load function * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up a function that fills in the GdkPixbufModule vtable, instead of looking up all the image functions individually; this means we can get type safety within modules for the loader functions. Also it means you don't have to keep the statically compiled and GModule versions in sync. * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init() * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init() * gdk-pixbuf.h: nuke gdk_pixbuf_init() * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init () here * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type): g_type_init() here 2001-01-22 Havoc Pennington <hp@redhat.com> * demos/testanimation.c: fix to reflect gdk-pixbuf changes * demos/testpixbuf.c: fix to reflect gdk-pixbuf changes * gtk/gdk-pixbuf-loader.c, gtk/gdk-pixbuf-loader.h: Remove, move back to gdk-pixbuf * gtk/gtktextiter.c, gtk/gtktextiter.h: add sentence equivalents to all the word functions * gtk/gtktextview.c (gtk_text_view_start_cursor_blink): return before doing anything on NULL layout or if we don't have the focus * gtk/testtext.c (fill_example_buffer): "justification" * gtk/gtktexttag.h, gtk/gtktexttag.c: change the tag attribute to be called "justification" not "justify" * demos/gtk-demo/textview.c (create_tags): "justification" * gtk/gtktextlayout.c (set_para_values): Handle char-wise wrapping

fix some shell typos 2001-05-04 Havoc Pennington <hp@redhat.com> * configure.in: fix some shell typos * gtk/gtkcolorsel.c (gtk_color_selection_destroy): warning fix * gtk/gtkimage.c: handle animations * gtk/gtkcheckbutton.c (gtk_check_button_size_request): request border_width * 2, not just border_width * gtk/gtkscale.c: add "format_value" signal to allow people to override the way values are drawn. (gtk_scale_get_value_size): fix width/height mistake, and compute size from actual displayed text, not from made-up text. * gtk/gtktexttag.c (gtk_text_tag_class_init): fix return type in signal registration * tests/testtext.c: Add "Remove all tags" menu item for testing * gtk/gtktextbuffer.c (gtk_text_buffer_remove_all_tags): implement * demos/gtk-demo/main.c (main): add hack so we can find modules without installing gtk * demos/gtk-demo/textview.c (insert_text): demo font scaling * gtk/gtkcellrenderertext.c: Add "scale" property (font scaling factor) (gtk_cell_renderer_text_set_property): remove some bogus g_object_notify * gtk/gtktexttag.c: add "scale" property which is a font scaling factor * gtk/gtktextlayout.c (add_text_attrs): add font scale attribute to layout * gtk/gtktextiter.c (gtk_text_iter_is_start): rename from gtk_text_iter_is_first 2001-05-04 Havoc Pennington <hp@redhat.com> * pixops/pixops.c (pixops_process): merge fix from stable: Patch from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes bug #50371. * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix confusion of using "src" instead of "p". (pixops_composite_color_nearest): Use a more accurate (and correct, to begin with) compositing method. This cures checks showing through on images with no alpha. * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing bytes unfilled. * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change area_updated signal to use signed ints. Removed animation-related signals. * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive rewrite action * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract all the pesky details. Remove old frame-based API. Make GdkPixbufAnimation an abstract base class, derived by the loaders.
