| * mesa: allow GL_BITMAP type in _mesa_image_image_stride()Brian Paul2009-05-221-13/+23
| | | | | | | | | | | | | | It's possible to hand a GL_COLOR_INDEX/GL_BITMAP image to glTexImage3D() which gets converted to RGBA via the glPixelMap tables. This fixes a failure with piglit/fdo10370 with Gallium.

* mesa: add another special/optimized case in _mesa_unpack_depth_span()Brian Paul2009-04-071-0/+11
|
* mesa: remove the noClamp parameter to _mesa_pack_rgba_span_float()Brian Paul2009-04-031-3/+6
| | | | | It was only set to GL_TRUE in one place where it isn't really needed (glGetTexImage(sRGB format)).
* mesa: add new signed rgba texture formatRoland Scheidegger2009-03-281-14/+3
| | | | | 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.
* mesa: use the IROUND() macro in pixel packing codeBrian Paul2009-03-181-108/+108
| | | | | | 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.
* mesa: added GL_DU8DV8_ATI case in _mesa_components_in_format()Brian Paul2009-03-121-0/+1
| | | | This gets hit when glTexSubImage2D() is called with format==GL_DU8DV8_ATI.
* mesa: move declarations before codeBrian Paul2009-03-121-2/+2
|
* mesa: add support for ATI_envmap_bumpmapRoland Scheidegger2009-03-121-3/+150
| | | | | | | | 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)
* mesa: Fix the size per pixel for packed pixel format data type.Xiang, Haihao2009-01-061-1/+1

* mesa: Clip copytexsubimage to read framebuffer bounds, not scissor region.Eric Anholt2008-12-181-1/+1
|
* mesa: Correct _mesa_clip_to_region() off-by-one.Eric Anholt2008-12-181-2/+2
| | | | | | | | | | 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.
* mesa: clamp luminance if needed.Xiang, Haihao2008-11-191-1/+1
| | | | | This fixes glReadPixels(GL_LUMINANCE, GL_FLOAT)/glGetTexImage(GL_LUMINANCE, GL_FLOAT) issue on fixed-point color buffers.

| | | | | | | | 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.
* mesa: revert f9f79c8d770e696249bd98c68b563f887562c974Xiang, Haihao2007-03-211-14/+5

| | | | | | | | 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.
