1999-12-20 Jonathan Blandford <jrb@redhat.com>
* 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 <jrb@redhat.com>
* 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.
1999-12-16 Federico Mena Quintero <federico@redhat.com>
* doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
before using the GdkPixbuf rendering functions. Thanks to Joe
Shaw <joe@off.net> for pointing this out.
1999-12-12 Federico Mena Quintero <federico@redhat.com>
* gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
conditional to see whether to link $(GNOME_LIBS) or not.
1999-12-13 Federico Mena Quintero <federico@redhat.com>
* 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 <federico@redhat.com>
* 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 <jrb@redhat.com>
* 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.
1999-12-10 Jonathan Blandford <jrb@redhat.com>
* 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.
ones can't be.
1999-12-09 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* gdk-pixbuf/gdk-pixbuf-drawable.c
(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.
1999-12-09 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* 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.
* 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
<arjan@fenrus.demon.nl>
* 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 <federico@redhat.com>
* 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 <federico@redhat.com>
* doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about
reference counting for GdkPixbuf structures.
1999-12-05 Arjan van de Ven
<arjan@fenrus.demon.nl>
Added missing "include <string.h>" to:
* gdk-pixbuf/io-ras.c
* gdk-pixbuf/io-bmp.c
* gdk-pixbuf/io-ico.c
1999-12-13 Federico Mena Quintero <federico@redhat.com>
* 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.
1999-12-05 Federico Mena Quintero <federico@redhat.com>
* 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.
1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
* 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.
1999-12-02 Federico Mena Quintero <federico@redhat.com>
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 <federico@redhat.com>

* src/gdk-pixbuf-loader.c: #include <config.h>
* 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.
1999-11-29 Owen Taylor <otaylor@redhat.com>
* 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.
1999-11-29 Federico Mena Quintero <federico@redhat.com>
* src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
should be made conditional, not blindly commented out.
1999-11-24 James Henstridge <james@daa.com.au>
* Makefile.am (SUBDIRS): libart must be built before gdk-pixbuf.
[ in gdk-pixbuf ]
1999-11-24 James Henstridge <james@daa.com.au>
* 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.
1999-11-22 Federico Mena Quintero <federico@redhat.com>
* 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.
* libgnomeui/gnome-stock-ids.[ch],libgnomeui/gnome-init.[ch],libgnome/gnomelib-init*.[ch]:
Uniquify the strings to save some memory.
* test-gnome/*.c: Make it build.
* configure.in: No imlib!
* libgnomeui/libgnomeui.h: Include gnome-druid-page-edge.h, not -start.h
1999-11-22 Havoc Pennington <hp@pobox.com>
* src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
<pnfisher@redhat.com> 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 <hp@pobox.com>
* 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
1999-11-22 Jonathan Blandford <jrb@redhat.com>
* 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.
1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
* 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 <lewing@gimp.org>
* 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.
Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
* 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.
1999-11-10 Federico Mena Quintero <federico@redhat.com>
* 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.
1999-11-09 Michael Fulbright <drmike@redhat.com>
* 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 Michael Fulbright <drmike@redhat.com>
* 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 Michael Fulbright <drmike@redhat.com>
* 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 <drmike@redhat.com>
* 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 <federico@redhat.com>
* doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
of the width, height, x, and y setting and pixels arguments.
1999-11-05 Federico Mena Quintero <federico@redhat.com>
* 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 <drmike@redhat.com>
* 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.
1999-11-05 Jonathan Blandford <jrb@redhat.com>
* src/gdk-pixbuf-io.c: second patch Arjan van de Ven
<arjan@fenrus.demon.nl> to autodetect/load the sunras files.
1999-11-05 Jonathan Blandford <jrb@redhat.com>
* src/io-ras.c (image_load): new file from Arjan van de Ven
<arjan@fenrus.demon.nl> to begin the ras loader.
999-11-04 Michael Fulbright <drmike@redhat.com>
* 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 Havoc Pennington <hp@pobox.com>
* 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 <hp@pobox.com>
* 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.
1999-11-03 Jonathan Blandford <jrb@redhat.com>
* src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
lib*gif!!!!
Also, some code cleanups to io-gif
1999-11-03 Michael Fulbright <msf@redhat.com>
* 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 Federico Mena Quintero <federico@redhat.com>
* 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 Larry Ewing <lewing@gimp.org>
* 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 <federico@redhat.com>
* src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
doofus. Return a distance, not a boolean, for opaque images.
1999-11-03 Federico Mena Quintero <federico@redhat.com>
* 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 Michael Fulbright <drmike@redhat.com>
* 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
1999-11-02 Jonathan Blandford <jrb@redhat.com>
* src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
for interlacing and progressive loading.
1999-11-02 Federico Mena Quintero <federico@redhat.com>
* 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.
* 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 <federico@redhat.com>
* 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 <jrb@redhat.com>
(ReadImage): lets get the offset right. This will let transparent
gifs work.
Right now, gifs with transparency, both interlaced and non-interlaced,
seem to work perfectly fine. I haven't tried grayscale gifs yet, and I
seem to be getting offset in my RGB buffer with non-alpha gifs. )-:
This leads to pretty, but incorrect, images.
-Jonathan
1999-10-30 <jrb@redhat.com>
* 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.
1999-10-29 Michael Fulbright <drmike@redhat.com>
* 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!
999-10-29 Michael Fulbright <drmike@redhat.com>
* 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 <drmike@redhat.com>
* 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 Federico Mena Quintero <federico@redhat.com>
* 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 <jrb@redhat.com>
* src/io-tiff.c (image_load_increment): started work on the tiff
non-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 <federico@redhat.com>
* 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 <hp@pobox.com>
* 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
