2009-04-07mesa: add another special/optimized case in _mesa_unpack_depth_span()Brian Paul
2009-04-03mesa: remove the noClamp parameter to _mesa_pack_rgba_span_float()Brian Paul
It was only set to GL_TRUE in one place where it isn't really needed (glGetTexImage(sRGB format)).
2009-03-28mesa: add new signed rgba texture formatRoland Scheidegger
This is a (partial) backport of the signed texture format support in OGL 3.1. Since it wasn't promoted from an existing extension roll our own.
2009-03-18mesa: use the IROUND() macro in pixel packing codeBrian Paul
It turns out some tests are sensitive to rounding vs. truncating when converting float color values to integers in glReadPixels(). In particular, this matters when the destination format is 5/6/5 or 4/4/4/4, etc.
2009-03-12mesa: added GL_DU8DV8_ATI case in _mesa_components_in_format()Brian Paul
This gets hit when glTexSubImage2D() is called with format==GL_DU8DV8_ATI.
2009-03-12mesa: move declarations before codeBrian Paul
2009-03-12mesa: add support for ATI_envmap_bumpmapRoland Scheidegger
add new entrypoints, new texture format, etc translate in texenvprogram.c for drivers using the mesa-generated tex env fragment program also handled in swrast, but not tested (cannot work due to negative texel results not handled correctly)
2009-01-06mesa: Fix the size per pixel for packed pixel format data type.Xiang, Haihao
2008-12-18mesa: Clip copytexsubimage to read framebuffer bounds, not scissor region.Eric Anholt
2008-12-18mesa: Correct _mesa_clip_to_region() off-by-one.Eric Anholt
Note how if: x + width == xmax + 0: width -= 0 x + width == xmax + 1: width -= 0 x + width == xmax + 2: width -= 1 So, the function was clipping to [xmin, xmax+1), not [xmin, xmax) like it was supposed to. Same for ymax.
2008-11-19mesa: clamp luminance if needed.Xiang, Haihao
This fixes glReadPixels(GL_LUMINANCE, GL_FLOAT)/glGetTexImage(GL_LUMINANCE, GL_FLOAT) issue on fixed-point color buffers.
2008-09-23mesa: Apply MSVC portability fixes from Alan Hourihane.José Fonseca
2008-09-23Added new _mesa_clip_copytexsubimage() function to do avoid clipping down in ↵Brian
the drivers. This should probably be pulled into main-line Mesa... (cherry picked from commit 324ecadbfdf9b944e059832f146451e4151dcb21)
2008-09-21mesa: refactor: move _mesa_update_minmax/histogram() into image.cBrian Paul
(cherry picked from commit eded7f010d344a909cf9c403eb3bdad91804d174)
2008-09-21mesa: refactor: move pixel map/scale/bias code into image.cBrian Paul
pixel.c is just the API-related code now.
2008-06-17mesa: fix inconsistent use of GL_UNSIGNED_INT vs. GL_UNSIGNED_INT_24_8_EXT ↵Brian Paul
for Z unpacking

2007-07-08Change float depthScale param to _mesa_unpack_depth_span() to GLuint depthMax.Brian
2007-07-08check depthScale value for optimized ushort->uint case (fixes bug 11474)Brian
2007-07-05stencil pixel map didn't work in _mesa_unpack_stencil_span(), bug 11475Brian

2007-05-10more indentation fixes, remove 'register' keywordsBrian
2007-05-10re-indent some codeBrian
2007-04-21fix SkipPixels bugs in _mesa_pack_bitmap(), bug 10690Brian
2007-04-19In _mesa_unpack_depth_span() look for special cases of GLuint->GLushort and ↵Brian
GLushort->GLuint conversion. This improves performance and avoids int/float/int conversion problems that can introduce errors during glCopyTexImage(). Another fix for the depth peeling algorithm.
2007-03-21mesa: revert f9f79c8d770e696249bd98c68b563f887562c974Xiang, Haihao
to fix #10232 Table6.1(in gl2.1) has been applied for glGetTexImage before calling into _mesa_pack_rgba_span_float.
2007-03-18mesa: SWAP_BUFF support when calling DrawPixels(DEPTH_COMPONENT)Xiang, Haihao
or TexImage(DEPTH_COMPONENT)
2007-03-16Colortable re-org.Brian
The pixel transfer path has three color table lookups. Use an array [3] to store that info, rather than separate variables.
2007-03-15implement byteswapping for all multi-byte types in ↵Brian
_mesa_pack_rgba_span_float(), bug 10298
2007-03-14Re-org of gl_pixel_attrib struct.Brian
Reorder fields according to the order in which the pixel transfer operations take place. Improve comments. Move the pixel maps out of gl_pixel_attrib since they're not supposed to be pushed/popped by glPush/PopAttrib. New gl_pixelmap and gl_pixelmaps structs to contain the pixelmaps.
2007-03-13mesa: _mesa_unpack_imageXiang, Haihao
1. take packed pixel data as a component 2. fix for GL_BITMAP when compiling glTexImage, etc into a display list: a. flip byte if lsbFirst is true since DefaultPacking->lsbFirst is false. b. handle SkipPixels
2007-03-12clean-up, simplify _mesa_image_row_stride()Brian
2007-03-12take GL_UNPACK_ALIGNMENT into account in _mesa_image_row_stride() for ↵Brian
GL_BITMAP type (bug 10261)
2007-03-09New IMAGE_RED_TO_LUMINANCE flag passed to _mesa_pack_rgba_span_float() to ↵Brian
fix glGetTexImage(GL_LUMINANCE) bug #10232.

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.

2006-10-13removed obsolete _mesa_pack_rgba_span_chan()Brian Paul
2006-10-12don't use temp storage in _mesa_convert_colors() when possibleBrian Paul
2006-10-11Added _mesa_convert_colors().Brian Paul
_mesa_clip_drawpixels() now handles Pixel.ZoomY==-1.
2006-09-11undo some accidental changes in _mesa_is_legal_format_and_type()Brian Paul
2006-09-10Redefine the BYTE_TO_FLOAT() and SHORT_TO_FLOAT() macros to avoid problemsBrian Paul
converting 0 to exactly 0.0 This goes against the OpenGL spec (see table 2.6) but solves problems when doing byte -> float -> ubyte conversion for particular texture formats.
