* io-bmp.c (OneLine32): Don't try to load an alpha channel
from the BMP, since there is no evidence that even 32bit
BMPs have an alpha channel. (#135502)
Fri Feb 20 22:25:32 2004 Matthias Clasen <maclas@gmx.de>
* io-bmp.c (DecodeHeader): Store and sanity-check the clrUsed field
from the header for use in DecodeColormap.

* gdk-pixbuf-loader.c (gdk_pixbuf_loader_init): Make it possible
to call gdk_pixbuf_loader_set_size (loader, 0, 0) by changing
the initial values of priv->width/height to -1.

* io-bmp.c (DecodeHeader): Call size_func once the size is known,
even if the module can't make use of the scaling information. If
size_func returns 0, don't allocate a pixbuf and return, if
necessary with an error.
* gdk-pixbuf.h:
* gdk-pixbuf-io.c (gdk_pixbuf_get_file_info): A new function
to determine the type and size of an image file without loading
it completely. (#53725)
2002-09-27 Federico Mena Quintero <federico@ximian.com>
* io-bmp.c (OneLine): Fix the update region notification to handle
top-to-bottom and bottom-to-top BMPs correctly.
* gdk-pixbuf-io.c (generic_image_load): New function for loading
an image from a file either via module->load or incrementally.
(prepared_notify): ModulePreparedNotifyFunc for generic_image_load.
(gdk_pixbuf_new_from_file): Use generic_image_load.
* io-bmp.c, io-ico.c, io-ras.c, io-wbmp.c: Remove trivial
implementations of module->load. (#71266)
* io-bmp.c (grow_buffer): New function to avoid crashes
on unchecked reallocs.
(DecodeHeader, DecodeColormap, decode_bitmasks,
DoCompressed): Use grow_buffer instead of g_realloc

skips and jumps.
2002-06-07 Federico Mena Quintero <federico@ximian.com>
* io-bmp.c (lsb_32):
(lsb_16): New functions to fetch 32 or 16-bit little-endian values
starting at a specific memory location. We do this instead of
GINT32_FROM_LE() as the latter is simply dereferences a cast,
which doesn't work on platforms with alignment requirements.
Fixes#84083.

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

* 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

area_updated signal to use signed ints. Removed animation-related
signals.

GdkPixbufLoader signals
* gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in

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.

* *.[hc]: applied patch from Andreas Persenius <ndap@swipnet.se> that
updates the license headers to the GNU Lesser General Public License,
as well as updating the copyright year to 2000.
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.

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_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_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-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/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
an lvalue.
* TODO: Populated.

(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.

* 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.
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.

* gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
ran through lclint.

* 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.
Ok minor changes.
No longer make a version.h, and cleaned up some code here and there, and added
a quickie dirty-hack rotation function. However, it rotates at the origin.
Is this what we want? Or do we want a rotate w.r.t. the center of the pixbuf?
Anyone.
