2005-10-03 Duncan Mak <duncan@novell.com>
* graphics.c (make_arcs):
* graphics-path.c (append_arcs): Helper functions for dividing
the arcs into smaller segments. Properly handles negative starting
angles and sweep angles.
* graphics-path.c (GdipAddPathArc, GdipAddPathPie):
* graphics.c (GdipDrawArc, make_pie): Simplified to make use of the
new helper functions.
2005-09-20 Jordi Mas i Hernandez <jordi@ximian.com>
* image.c, gdip.h, image.c: Creates the surface and then creates the
graphics context. This is not only reduces the operations need it, also
and more avoids to lose the values that we have init into cairo.
2005-09-21 Peter Dennis Bartok <pbartok@novell.com>
* bmpcodec.c: The alpha value in a indexed color table is never
valid. Since the indexed bitmap code uses the color value from
the table directly, we need to always set the alpha to 0xFF. This
matches MS behaviour (Custom cursors are a good testcase for this,
since they are generated through an intermediate BMP step)
2005-09-20 Jordi Mas i Hernandez <jordi@ximian.com>
* bitmap.c: Fixes bug 76152
2005-09-19 Peter Dennis Bartok <pbartok@novell.com>
* graphics.c: Remove AA setting; fixes bug #76135. Needs to have a save
restore of previous AA settings

2005-08-24 Peter Bartok <pbartok@novell.com>
* gdip.h: Removed prototypes for internal strikethrough and underline
functions; those are no longer used
* font.c:
- Cairo switched to positive font descent number, fixed code to match
- Removed unused methods for strikethrough and underline; drawstring
handles that behaviour internally
* graphics.c (DrawString): Cairo switched to positive descent values
for font extents, switched the code to handle that
2005-08-24 Jordi Mas i Hernandez <jordi@ximian.com>
* graphics.c: fixes gcc 4 warning
* general.c: from_cairoformat_to_content function

2005-08-24 Hisham Mardam Bey <hisham.mardambey@gmail.com>
* pen.c : remove debugging printf.
2005-08-24 Jordi Mas i Hernandez <jordi@ximian.com>
* hatchbrush.c, lineargradientbrush.c. Cairo has changed the format
enum parameter for cairo_surface_create_similar. This fixes many samples
not running.
2005-08-23 Peter Bartok <pbartok@novell.com>
* graphics.c: The original CalculateStringWidths method was dependent
on FT and internal knowledge of cairo font matrix behaviour, and the
function broke with the newer cairo due to changes to this behaviour.
Renamed the original to CalculateStringWidthsUTF8 and wrote a new
method which uses cairo_text_extents to calculate character widths.
This is somewhat slower but works font-backend independent.
* general.c: Added ucs2 to utf8 char encoder and decoder (allows
faster calculations than the malloc-dependent utf8 string functions)
* gdip.h: Added prototypes for utf8 character functions
2005-08-22 Jordi Mas i Hernandez <jordi@ximian.com>

2005-07-21 Duncan Mak <duncan@novell.com>
* graphics.c (make_pie): Fix #75475. Use sweepAngle (instead of
endAngle) when drawing the arcs.
"The arc always starts at 0. For the fill method the effect is that
a pie ending at 360 will fill the whole circle..."
Patch from Patrick Michel <PBMichel@web.de>.
2005-07-01 Jonathan Gilbert <logic@deltaq.org>
* bitmap.c: Fixed bug in GdipCreateBitmapFromScan0's default palette
initialization. Corrected GdipBitmapGetPixel to permit the operation
on indexed bitmaps (uses pixel streams :-).
2005-06-30 Peter Bartok <pbartok@novell.com>
* general.c (ucs2_to_utf8): Added argument to allow specifying the
string length (to allow converting substrings)
* graphics.c (MeasureOrDrawString, MeasureString): Fixed handling

- Removed TabWidth from GpStringDetailStruct, was obsoleted by
tab-redo
- Changed prototype of ucs2_to_utf8(), added length argument
2005-06-21 Geoff Norton <gnorton@customerdna.com>
* graphics.c (GdipCreateFromQuartz_macosx): Set the size of the
context in the bounds structure. Fixes #75326
2005-06-13 Peter Bartok <pbartok@novell.com>
* bitmap.c, image.c, gdip.h, bmpcodec.c, jpegcodec.c, tiffcodec.c,
gifcodec.c, gifcodec.h, pngcodec.c, pngcodec.h: Re-applied two
previous changes, since #75254 is now fixed
2005-06-13 Peter Bartok <pbartok@novell.com>
* Rolled back last two checkins, to r45601, pre palette patch, due
to the regression caused with Icons (bug #75254)
2005-06-07 Geoff Norton <gnorton@customerdna.com>
* bmpcodec.c:
* image.c: Fix some (un)signed mismatch issues so that gdiplus
will compile on gcc 4.0 again with -Werror
2005-05-30 Jonathan Gilbert <logic@deltaq.org>
* bitmap.c: Added indexed pixel formats to
gdip_is_a_supported_pixelformat().
* bitmap.c: Added gdip_is_an_indexed_pixelformat(). Added its
prototype to gdip.h; not sure if this is the correct place.
* bitmap.c: Added support for PixelFormat.Format4bppIndexed to
GdipCreateBitmapFromScan0 (maps to CAIRO_FORMAT_A8, like
PixelFormat.Format8bppIndexed). Palettes will be created
as needed. Bitmaps with a 4bpp indexed pixel format will be
given 256-entry ColorPalette structures, as the cairo_format
indicates 8-bit data.
* bitmap.c: GdipCreateBitmapFromScan0 now computes stride for
indexed pixel formats differently, and does not convert
indexed pixel formats to 32-bit RGB. It also makes images with
32-bit pixel formats initially black instead of initially
transparent and fills the palette with the default values for
1-, 4- and 8-bpp indexed images.
* bitmap.c: Added support for indexed images to
gdip_bitmap_clone_data_rect().
* bitmap.c: Rewrote GdipBitmapLockBits () to be maintainable
while supporting indexed pixel formats. Added
gdip_can_window_without_copy (), gdip_is_a_32bit_pixelformat (),
gdip_make_alpha_opaque () and gdip_is_an_alpha_pixelformat ().
* bitmap.c: Moved gdip_from_ARGB_to_RGB () and
gdip_from_RGB_to_ARGB () above gdip_bitmap_change_rect_pixel_format (),
so that gdip_bitmap_change_rect_pixel_format () can call them.
* bitmap.c: Added struct StreamingState and methods
gdip_init_pixel_stream (), gdip_pixel_stream_has_next (),
gdip_pixel_stream_get_next () and gdip_pixel_stream_set_next () to
work with Bitmaps of various formats in an abstract way.
gdip_pixel_stream_get_next () returns and
gdip_pixel_stream_set_next () accepts 32-bit ARGB values for 15,
16, 24, 32, 48 and 64 bit formats and palette indices for 1, 4 and
8 bit formats. gdip_pixel_stream_get_next () and
gdip_pixel_stream_set_next () cannot be mixed; call either one or
the other on a given stream, but never both.
* bitmap.c: Rewrote gdip_bitmap_change_rect_pixel_format to use
pixel streams, which adds support for indexed pixel formats and
increases maintainability.
* bitmap.c: Added check to GdipBitmapSetPixel ensuring that
the bitmap is not indexed (despite what MSDN says, in
practice Microsoft's implementation rejects SetPixel on
indexed Bitmaps).
* bitmap.c: Added gdip_convert_indexed_to_rgb (), which will
be used by the functions implementing DrawImage, since
gdip_bitmap_ensure_surface () is not compatible with indexed
image data.
* image.c: Added support for indexed pixel formats in
GdipDrawImageRect and GdipDrawImageRectRect. The support is
for the image being drawn to be indexed, not the image
being drawn on. :-)
* image.c: Implemented GdipGetImagePalette (),
GdipSetImagePalette () and GdipGetImagePaletteSize ().
* bmpcodec.c: Corrected gdip_bitmap_fill_info_header ()'s
interpretation of pixel bit widths.
* bmpcodec.c: Added include directive for gdipImage.h, for
utility function gdip_get_pixel_format_bpp ().
* bmpcodec.c: Updated gdip_bitmap_save_bmp () to save the
palette for indexed bitmaps. Also modified the save function
to not swap bytes for indexed pixel formats on big-endian
architectures.
* bmpcodec.c: Updated gdip_read_bmp_image_from_file_stream ()
to maintain 1, 4 and 8 bpp indexed data instead of converting
it on-the-fly to 32 bpp RGB data.
* bmpcodec.c: Updated gdip_get_pixelformat () to translate
a bit width of 1 into Format1bppIndexed.
* bmpcodec.c: Added support for decoding 4- and 8-bit RLE
bitmaps.
* gifcodec.c: Updated gdip_save_gif_image () to support saving
indexed images. Also, an off-by-one error in the 32-bit ARGB
side of the encoder was corrected (the image was translated
left one pixel).
* jpegcodec.c: Updated gdip_save_jpeg_image_internal () to
reject 8bpp indexed images that are not grayscale (the
previous behaviour was to assume all 8bpp indexed images
are grayscale).
* tiffcodec.c: Updated gdip_save_tiff_image () to reject
indexed images as NotImplemented, for now at least.
* pngcodec.c: Updated gdip_load_png_image_from_file_or_stream ()
to handle 1-, 4- and 8-bit PNG files separately, without
upsampling the data to 32-bit RBG.
* gdip.h: Fixed the set_pixel_bgra () macro; a lack of
parentheses and no cast down to 'unsigned char' was making
expressions like set_pixel_bgra (&array[i], ...) fail to
compile, and it wasn't a proper statement; it could not be used
in a construct like "if (...) set_pixel_bgra(...); else ...;".
2005-05-25 Peter Bartok <pbartok@novell.com>
* graphics.c, font.c, image.c, general.c, gdip.h: Replaced UTF8/UTF16
conversion with UCS2/UTF8 conversion (The MS APIs do not use UTF16)
2005-05-24 Duncan Mak <duncan@novell.com>
* graphics-path.c (append_arc): Append PathPointTypeLine instead
of PathPointTypeStart, so that arcs will be joint properly. This
fixes bug #75015. Thanks to Elliot Paquette for reporting and
fixing this bug.
2005-05-24 Duncan Mak <duncan@novell.com>
* graphics.c (make_pie, GdipDrawArc):
* graphics-path.cs (GdipAddPathArc, GdipAddPathPie): Rewrote the
code for calculating arcs: instead of drawing two arcs via a
mid-point, draw multiple arcs at intervals of 90 degrees. This
results in prettier arcs/pies and a better match to the output
produced by MS.
2005-05-20 Duncan Mak <duncan@novell.com>
* graphics-path.c (GdipAddPathArc): Added a special case for
drawing ellipses, and remember to use abs() with 'sweepAngle' to
ensure correctness when the angle is negative.
This is basically a port of the previous commit.
2005-05-09 Duncan Mak <duncan@novell.com>
* graphics.c (make_pie, GdipDrawArc): when evaluating angles,
always use abs(). This fixes the drawing of arcs and pies when the
sweep angle is negative.
Bug #63360 has also been fixed. This was a bug reported by
Ravindra in August '04 about a hang when "the difference between
width and height of rectangle is 1 and angles sum is close to
360". My change doesn't affect this bug. #63360 didn't hang in
libgdiplus 1.1.7 as is, so it was actually fixed by the Cairo
guys.

2005-01-04 Peter Bartok <pbartok@novell.com>
* graphics.c (MeasureOrDrawString): Return 0 instead of

- Streamlined CalculateStringSize, combined with gdip_utf8_to_glyphs
- Removed unused parts of gdip_utf8_to_glyphs() and
CalculateStringSize
- Dropped unneeded allocation of glyph memory
* gdip.h:
- Removed gdip_utf8_to_glyphs prototype
2004-11-09 Peter Bartok <pbartok@novell.com>
* graphics.c
(MeasureOrDrawString): Added check to prevent crash if bogus data is
returned from freetype.
(MeasureOrDrawString): Instead of calling GdipFillRectangle we call
cairo directly to draw underlines and strikeouts
