2ea856a21d When width/height are 0, copy the src to the dest, don't just return. (#3017) 2005-08-22 12:15:28 +00:00

16ce285251 Remove warning about fbCompositeTrans_0888xnx0888 not being tested on big-endian, it's not helpful at this point. 
Only define _cairo_pixman_have_mmx for fbHaveMMX when the symbol will actually exist.

d809e82980 Special case alpha values of 0 and 0xff. (fbCompositeSrc_8888x8888mmx): Add an MMX implementation for a common operation when using pixman. 
Prototype for the new function.
Call the new function where appropriate.

f5afeec18a Special case projective transforms so we can avoid doing the expensive 64-bit math. Unroll the bilinear interpolation loops for an extra boost. 2005-08-18 18:46:30 +00:00

24ba58e7f5 For the source operator, the output should be cleared if the mask is zero. This fixes the MMX code to match the fbcompose code. 
Fix a logic mistake that caused the MMX functions not to be used in many cases.

0398085a6f Split the MMX code into a separate libtool library to avoid applying the MMX CFLAGS to all of the pixman code. Idea and code from Owen Taylor. 
Update the mangling header file to include the MMX symbols.

9ae7d8a13b Port MMX code from xserver to pixman. 
Add an fbpict.c ported from the latest in xserver/fb, including hooks to the MMX code where appropriate. This replaces the old ic.c file.
Replaced by fbpict.c.
Move some X server macros from fbpict.c up into icint.h to keep the diff small.
Add fbmmx and fbpict.c, remove ic.c.
Add a check for the MMX intrinsics. gcc >= 3.4 is required.

910d824b3d Port fbcompose.c from xserver into pixman. Add #defines for gradients, convolution filters, and indexed colour formats to keep the patch small. Use pixman regions instead of X server regions as appropriate. 
Remove iccompose.c, replaced by fbcompose.c.
Add a slightly-trimmed version of fbpict.h from xserver/fb to make the port smaller and cleaner.
Use the redundant fbpict.h defines and add in the struct for indexed colour support.
Remove defines now in fbpict.h.
Add some constants and types required by fbcompose.c
Add fbcompose.c and fbpict.h, remove iccompose.c.

0fc4192104 From Keith Packard <keithp@keithp.com>, 
Build pixman internally as a private part of cairo, with suitable name changes to avoid any visible pixman symbols in the cairo library:
Descend into pixman.
Drop libpixman from Requires.
Don't check for libpixman. Check version of pkg-config and use Requires.private instead of Requires in cairo.pc if possible. Generate pixman Makefiles.
Rip out release-publish target and installation of libpixman.pc.
Add pixman-remap.h. Drop libpixman.la target.
Fix to include config.h rather than ../config.h
This is the cpp magic to rename all pixman functions from the various fb, Fb, INT_pixman, pixman, Render, _Render, or no prefix to _cairo_pixman_ prefixes.
Include pixman-remap.h to get all the cairo-internalized names.
Add -Ipixman/src to get at pixman-remap.h.

de87ebcc1c Fix problems in render fb implementation found by rendercheck: 
- fbCombineSaturate was pointed at fbCombineDisjointOver, instead of fbCombineDisjointOverReverse as it should. Instead, point fbCombineDisjointOverReverse at fbCombineSaturate (which is likely to be faster).
- fix previously-unused fbCombineSaturate implementation.
- fbCombineMaskAlphaC was just a copy of fbCombineMaskValueC. Make it do what it's supposed to (return a cs.alpha).
- fbCombineAtopC didn't invert the source alpha value.
- fix copy'n'paste errors in fbCombine(Dis/Con)jointGeneralC, also source alpha wasn't treated in a component fashion.

71e560a8fa Temporarily disable the 24bpp WORKING_UNALIGNED_INT because of a crash when using electric-fence when accessing hte last pixel of a drawable (last pixel is 3 bytes, read it as a 4 byte word, and you're reading one extra pixel, which doesn't normally matter, but does in a few rare cases). Should be easy to work around, but that will come later.

2b20b7a230 Fix up the fast-path compositing operators; those are useful for sources without alpha, but can't be used for sources with alpha. Also, replaced fbCompositeSrcSrc_nxn with call to fbBlt as this function must handle 1, 4, 8, 16, 24, 32 bpp objects. Would be nice to optimize fbBlt for common cases involving 8, 16, 24 and 32bpp.

ba87f1324f Optimize spans where the same value is being added to multiple pixels. This improves the speed of rasterizing wide trapezoids. 
Add an INLINE macro that matches the one from fbpict.h in xserver/fb.

171b053347 Whitespace fix. (pixman_image_destroy): Fix leak of the clip region associated with an image. (NOTE: xserver/render doesn't have the same bug since it has FreePicture that calls into both DestroyPicture and DestroyPictureClip separately). 2005-07-14 11:41:00 +00:00

2ff04df852 Begin merging in newer fb code. 
The code comes from keithp: Initial import of Composite extension along with name change from Apportion. Added some accelerated code to fbpict to make this initial hack a bit faster. "real" extension bits to follow.

ae96f5db6c Split clipping into separate source and destination operand clips. By default, source operands are not affected by any client clipping. This matches the desired semantics for cairo. When this code is ported back to the X server, that will have to select the clipping option which clip source operands to the client clip. 2005-05-26 13:02:31 +00:00

949daa1bc9 libpixman creates an A8 format object and sometimes forgets to destroy (when the bounds of the trapezoids are empty). Avoids creating the format object in that case.
