2011-02-28mesa: move PBO-related functions into a new fileBrian Paul
2010-12-03swrast: restructure some glReadPixels() codeBrian Paul
2010-12-03swrast: accept GL_RG in glReadPixels()Brian Paul
Fixes http://bugs.freedesktop.org/show_bug.cgi?id=32088
2010-10-27swrast: Print out format on unexpected failure in _swrast_ReadPixels.Vinson Lee
2010-10-23mesa: split up the image.c fileBrian Paul
New files: pack.c - image/row packing/unpacking functions pixeltransfer.c - pixel scale/bias/lookup functions
2010-10-13Drop GLcontext typedef and use struct gl_context insteadKristian Høgsberg
2010-09-23mesa: Remove EXT_convolution.Eric Anholt
More optional code.
2010-09-07mesa: Set the base format of GL_ALPHA FBOs and teach swrast about it.Eric Anholt
Fixes assertion failures in fbo-alpha with a debug build of Mesa. Bug #29781.
2010-07-30mesa: Remove unnecessary headers.Vinson Lee
2010-06-10swrast: When reading from a 0-bits r,g,b channel, return 0 not 1.Eric Anholt
It looks like we were reading a fractional value, multiplying by an enormous negative value, then stuffing that value into a bitfield assuming it was already clamped. This becomes relevant for GL_ALPHA or R/RG FBOs.
2010-03-05swrast: Adjust colors based on ReadBuffer visual, not context visualIan Romanick
In the presence of FBOs, the visual of the context may not match the, possibly fake, visual of the current ReadBuffer. Note that the caller of adjust_colors correctly uses the visual of the ReadBuffer. Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>
2010-03-03swrast: Remove support for ReadPixels from a color-index bufferIan Romanick
Signed-off-by: Ian Romanick <ian.d.romanick@intel.com>
2010-02-19Replace _mesa_malloc, _mesa_calloc and _mesa_free with plain libc versionsKristian Høgsberg
2010-01-12swrast: Remove unnecessary header from s_readpix.c.Vinson Lee
2009-11-11swrast: handle additional Z24 formats in read_depth_pixels()Brian Paul
2009-11-10swrast: update renderbuffer format assertionsbrian
2009-10-03swrast: Move up state validation in _swrast_ReadPixels.Michel Dänzer
This ensures the driver won't map the wrong set of textures.
2009-09-03mesa: consolidate PBO map/unmap helpersBrian Paul
Instead of _mesa_map_readpix_pbo() use _mesa_map_pbo_source(). Instead of _mesa_map_drawpix_pbo() and _mesa_map_bitmap_pbo() use _mesa_map_pbo_dest().
2009-01-30swrast: replace RENDER_START/FINISH macros with inline functionsBrian Paul
2008-09-18mesa: prefix a bunch of #include lines with "main/".Brian Paul
This is another step toward removing a whole bunch of -I flags from the cc commands. Still need to address driver code...
2008-03-21Refactor PBO validate/map code.Brian
We always need to do PBO validation, so do that in core Mesa before calling driver routine.
2008-03-21add a number of PBO validate/map/unmap functionsBrian
Helper functions for (some) drivers, including swrast.
2007-12-18Fix mismatched map/unmap of buffers in swrast read/drawpixels error paths.Eric Anholt

2007-02-01New SWspanarrays attribs[] array.Brian
Replace texcoord[], varying[], etc. arrays with single attribs[] array, indexed by FRAG_ATTRIB_* values. Eliminates need to copy data into fragment program machine input registers. Will lead to future clean-ups.
2007-01-23fixes for C++ warnings/errorsBrian
2006-11-14Make sure RENDER_FINISH is called on the zero pixel case. Reported byKeith Whitwell
Haihao Xiang.
2006-10-22Color clamping fixes.Brian Paul
2006-10-13Consolidate, move, fix code related to color index and stencil image transferBrian Paul
operations (shift, offset, table lookup, etc).
2006-10-13In _mesa_pack_rgba_span_float() we don't need to make a temporary copy ofBrian Paul
incoming colors when applying pixel transfer ops. In all cases, the caller either indicates there's no pixel transfer ops, or the incoming colors are coming from temporary storage already and can be safely modified.

2006-10-12adjust_colors() function replaces old _mesa_chan_to_float_span() function.Brian Paul
2006-10-12Lots of changes to support runtime renderbuffer depths.Brian Paul
_swrast_read_rgba_span() now takes a datatype parameter. New optimization for glReadPixels(format=GL_RGB). New glCopyPixels optimization for the simple, common cases.

2006-05-07minor clean-ups around DepthScale/BiasBrian Paul
2006-03-22Need to check for new state and do readpixels/drawpixels clipping afterBrian Paul
we call RENDER_START since that may involve validating the drawable and updating its dimensions.

Attachment[BUFFER_DEPTH/STENCIL].Renderbuffer. The former may be wrappers around combined depth/stencil renderbuffers attached at the later points.

Zoomed DrawPixels of packed depth/stencil works now.
