that the weights sum up to the correct total without introducing
negative weights.
(tile_make_weights, bilinear_make_fast_weights,
bilinear_make_weights): Use correct_total.
Fri Feb 8 23:11:15 2002 Owen Taylor <otaylor@redhat.com>
* pixops/pixops.c: Force all weight arrays to sum exactly
to 65535. (Fixes#70971, reported by Federico Mena Quintero)

of run_end_index and fix some edge cases.
* pixops/{scale_line_22_33_mmx.S, composite_line_22_4a4_mmx.S:
composite_line_color_22_4a4_mmx.S}: Handle the case where
dest <= dest_end properly. (#52001)

for alpha compositing and how to implement them quickly.
2001-12-13 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gdk-pixbuf-animation.c, gdk-pixbuf-loader.c, gdk-pixpuf.c,
io-gif-animation.c, io-gif.c, io-tiff.c, test-loaders.c: Remove
assorted G_OBJECT casts where unnecessary.
* gdk-pixbuf-loader.c: Call g_object_ref and g_object_unref
instead of gdk_pixbuf_animation_ref and gdk_pixbuf_animation_unref
resp.
* gdk-pixbuf-csource.c, io-bmp.c, io-gif-animation.c, io-ico.c,
io-jpeg.c, io-png.c, io-pnm.c, io-ras.c, io-tga.c, io-wbmp.c,
io-xbm.c, io-xpm.c, test-gdk-pixbuf.c: Dito for gdk_pixbuf_ref and
gdk_pixbuf_unref.
* Makefile.am, pixops/Makefile.am: Compile everything with
-DG_DISABLE_DEPRECATED -DGDK_PIXBUF_DISABLE_DEPRECATED
* gdk-pixdata.c: Use g_ascii_strup() instead of g_strup().
* io-xpm.c: Use g_ascii_strcasecmp() instead of g_strcasecmp().
* demos/testpixbuf-drawable.c, demos/testpixbuf-save.c,
demos/testpixbuf-scale.c, demos/testpixbuf.c: Call g_object_ref
and g_object_unref instead of gdk_pixbuf_ref and gdk_pixbuf_unref
resp.
2001-10-28 Hans Breuer <hans@breuer.org>
* gtk/gtkfontsel.c : use g_strcasecmp(), some poor platforms
don't have strcasecmp()
* gtk/gtktextview.c : to fix crashing on e.g. TextView::find need
to remove the idle funcs in gtk_text_view_destroy (). To reduce
code duplication wrap it in its own function and use it in
gtk_text_view_unrealize () and gtk_text_view_destroy_layout ()
* gdk/win32/gdkdrawable-win32.c : implement the finalize
method like the X11 version does, allow to set_colormap NULL
* gdk/win32/gdkwindow-win32.c : adapt GdkWindowImplWin32::
set_colormap, also some adaption to X11 version :
(gdk_window_hide) call _gdk_window_clear_update_area
(gdk_window_reparent) call _gdk_window_init_position
* gdk/win32/gdkwindow-win32.c (gdk_window_set_geometry_hints) :
call gdk_window_resize() after all hints are set, because the
window resizing process (WM_GETMINMAXINFO) takes all of them into
account

* gdk/makefile.msc gdk/win32/makefile.msc gdk-pixbuf/makefile.msc
gdk-pixbuf/pixops/makefile.msc gtk/makefile.msc.in tests/makefile.msc :
from now on use make.msc from $(TOP)/glib/build/win32
* gtk/stock-icons/makefile.msc : add stock_missing_image
2001-08-19 Sven Neumann <sven@gimp.org>
* pixops/pixops.c: applied some simple but effective optimizations
to pixops_composite_nearest() and pixops_composite_color_nearest().
* gdk-pixbuf-csource.c: Add missing <stdlib.h> include.
* io-png.c: (setup_png_transformations): Add ifdef so we compile
without warnings with G_DISABLE_CHECKS on.
* io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
const.
* io-wbmp.c: (getin), (get_mbi): Add a missing const.
* io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
unused locals and add an initial value to quiet the compiler's
unintialized variable warning.
* pixops/pixops.c: Put an ifdef around some dead code.
Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
* pixops/Makefile.am (noinst_LTLIBRARIES): Switch
over to the new include flags AC_SUBST(). (Problem
pointed out by Mikael Hermansson.)
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.
2001-02-19 Alexander Larsson <alexl@redhat.com>
* gdk/linux-fb/gdkimage-fb.c (gdk_image_new_bitmap):
Copy data and free data with free().
* gdk-pixbuf/gdk-pixbuf.c:
* gdk-pixbuf/io-jpeg.c:
* gdk-pixbuf/io-png.c:
Use g_try_malloc/g_free instead malloc/free.
* gdk-pixbuf/test-gdk-pixbuf.c:
Must... initialize... gobject...
* gdk-pixbuf/pixops/timescale.c:
* gtk/gtkcalendar.c:
Use g_malloc instead of malloc.
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
Wed Nov 15 18:39:40 2000 Owen Taylor <otaylor@redhat.com>
* **/Makefile.am : remove unecessary rules for win32-specific
config-substituted targets. If you want these rules, use
--enable-maintainer-mode (called automatically by autogen.sh).
Stops a lot of unneccessary make-time warnings.
* gtk/gtktext{layout,display}.c: Factor in total width as
well as screen when figuring alignment for word-wrap as well as
no wrap; this is necessary to handle lines that cannot be wrapped
at all.
2000-10-06 Havoc Pennington <hp@redhat.com>
* Makefile.am (SRC_SUBDIRS): contrib subdir
* gdk/gdkpixbuf.h: Move GdkPixbufAlphaMode to gdk-pixbuf library,
so it can be used in Xlib version
* demos/testpixbuf.c (update_timeout): error checking from 1.0
tree
* gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_pixbuf): Sync
change from 1.0 tree that returns first frame of animation
if the loaded file is an animation.
* contrib: add new directory to hold stuff that comes with GTK+
but isn't really part of GTK+ (for now, gdk-pixbuf-xlib)
* configure.in: add contrib/*
2000-10-06 Havoc Pennington <hp@redhat.com>
* gdk-pixbuf.h: add GdkPixbufAlphaMode
2000-10-06 Havoc Pennington <hp@redhat.com>
This entry is a summary of the merged-in changes from 1.0.
Relevant original ChangeLog entries are spliced in after
this entry; the files they refer to are from the 1.0
gdk-pixbuf sources.
* pixops/pixops.c (pixops_composite_nearest): sync a small fix
from 1.0
* io-xpm.c (xpm_seek_string): add fscanf error check from 1.0

Russell
2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
* gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
last nights code was still "broken". Should now properly handle
all error conditions gracefully.
2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
* gdk-pixbuf/io-pnm.c: Rewrote.
2000-09-09 Federico Mena Quintero <federico@helixcode.com>
* gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
the correct dest offset.
2000-08-25 Federico Mena Quintero <federico@helixcode.com>
* gdk-pixbuf/io-xpm.c: #include <unistd.h>
2000-08-05 Larry Ewing <lewing@helixcode.com>
* gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
* gdk-pixbuf/io-xpm.c: same as above.
2000-07-26 Michael Meeks <michael@helixcode.com>
* gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
g_malloc a malloc.
2000-07-21 Larry Ewing <lewing@helixcode.com>
* gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
xpm at least supports the progressive interface like the one in
io-tiff.c. This should be reimplemented as an actual progressive
loader.
2000-07-19 Jonathan Blandford <jrb@redhat.com>
* demo/pixbuf-demo.c (update_timeout): changed scaling level to
make it look better.

lines of AC_TRY_COMPILE.
* .cvsignore updates
2000-07-23 Tor Lillqvist <tml@iki.fi>
Win32 build setup:
* makefile.mingw.in
* pixops/makefile.mingw.in
* pixbuf_*.def: New files.
* Makefile.am
* pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
* gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
New function, to get the GTK+ installation directory from
the Windows Registry, where the installation program
for whatever software includes GTK+ has stored it.
Used to avoid having hardcoding the directory where to look for
loaders. This function is needed by gtk, too, so it should
really be just in one place. Maybe a small static library
one level up from here?
* gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
* gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
Open file in binary mode. This *is* standard C. (No-op on Unix,
of course.)
* io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
* io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
mktemp() and open().
(gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
* pixops/*.S: The Gas from mingw32 doesn't like the .type
pseudo-op. Conditionalise on __MINGW32__, but probably
should conditionalise on Gas version instead? Or could we
do without .type on all systems?
* pixops/timescale.c: Use g_get_current_time()
instead of gettimeofday().
Wed Jun 21 16:38:13 2000 Owen Taylor <otaylor@redhat.com>
* gdk-pixbuf/* docs/reference/gdk-pixbuf/*: Welcome aboard,
gdk-pixbuf.
* gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
fixups for GObject.
* gdk/Makefile.am gdk/gdkpixbuf-render.[ch] gdk/gdkpixbuf.[ch]: Bits of
gdk-pixbuf with GDK dependencies moved into GDK.
* gtk/Makefile.am gtk/gdk-pixbuf-loader.[ch]: Temporarily
move gdk-pixbuf-loader here until GObject has signals.
* demos/: New directory of demos. Move demos from
gdk-pixbuf here.
* demos/pixbuf-init.c: Small bit of code to check for
loaders in ../gdk-pixbuf/.libs/gdk-pixbuf, and if found,
set GDK_PIXBUF_MODULEDIR appropriately.
* gdk/gdkcompat.h: Remove GDK_DRAWABLE_PIXMAP compat
define which no longer makes sense.
Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
* 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.
CvS: Added Files:
* 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.
* 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.)
2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
* gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
$(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
2000-04-11 Federico Mena Quintero <federico@helixcode.com>
Most of this patch is based on a patch by Havoc Pennington

* 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.

(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.

* 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.
2000-03-27 Owen Taylor <otaylor@redhat.com>
* gdk-pixbuf/pixops/pixops.c: Fix problem with
precendence of >> and & which was keeping composite_color
from working with non-gray images.
Mon Jan 31 12:38:50 2000 Owen Taylor <otaylor@redhat.com>
* gdk-pixbuf/pixops/pixops.c (scale_line): Fix from Peter
Wainwright to fix 4a => 4a scaling.
