| * 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 GL_DOUBLE case in _mesa_sizeof_type()Brian Paul2009-05-071-0/+2

* 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.

* mesa: refactor: move pixel map/scale/bias code into image.cBrian Paul2008-09-211-1/+421
| | | | pixel.c is just the API-related code now.

| | | | | | | | 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

* Colortable re-org.Brian2007-03-161-3/+3

* Re-org of gl_pixel_attrib struct.Brian2007-03-141-6/+6
| | | | | | | | 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.

* In _mesa_pack_rgba_span_float() we don't need to make a temporary copy ofBrian Paul2006-10-131-17/+9
| | | | | | | 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.
