* mesa: use F_TO_I() instead of IROUND()Brian Paul2012-05-191-110/+110
| | | | | | | | Use it where performance matters more and the exact method of float->int conversion/rounding isn't terribly important. There should no net change here since F_TO_I() is the new name of the old IROUND() function. Reviewed-by: José Fonseca <[email protected]>
* mesa: add _mesa_rebase_rgba_float/uint() functionsBrian Paul2012-03-081-0/+91
| | | | | | | | | These will be used by glReadPixels() and glGetTexImage() to fix issues with reading GL_LUMINANCE and other formats. NOTE: This is a candidate for the 8.0 branch. Reviewed-by: José Fonseca <[email protected]>
* mesa: Fix copy-and-paste error in _mesa_pack_rgba_span_floatIan Romanick2012-02-021-3/+2
| | | | | | | | | | | GL_RG_INTEGER only has two components, not three. I'll be surprised if anyone ever tries to glReadPixels(..., GL_SHORT, GL_RG_INTEGER, ...). This was found by inspection. NOTE: This is a candidate for the 8.0 branch. Signed-off-by: Ian Romanick <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

* mesa: When unpacking signed integer pixel data, don't clamp to 0.Eric Anholt2012-01-271-33/+12
| | | | | | | | | | | | In the core, we always treat spans of int/uint data as uint, so this extract function was truncating storage of integer pixel data to a n int texture to (0, max_int) instead of (min_int, max_int). There is probably missing code for handling truncation on conversion between pixel formats, still, but this does improve things. NOTE: This is a candidate for the 8.0 branch.

* mesa: Add clamping for packing of integer data.Eric Anholt2012-01-271-4/+4
| | | | | | | | | | Mostly fixes piglit EXT_texture_integer/getteximage-clamping. The remaining failure involves precision loss on storing of int32 texture data (something I knew was an issue, but wasn't trying to test). NOTE: This is a candidate for the 8.0 branch.

* mesa: Add the remaining from/to types for GL_EXT_texture_integer (and R/RG).Eric Anholt2012-01-241-51/+61
| | | | | | | | | | | This aborts and crashes in intel oglconform's int-textures into being just rendering failures. Clamping isn't handled yet. v2: Add missing "break". v3: Drop the int/uint distinction, since they don't need different clamping. NOTE: This is a candidate for the 8.0 branch.

* mesa: Add missing GL_RG_INTEGER casesIan Romanick2012-01-041-0/+39
| | | | | | | | Adds two missing '|| srcFormat == GL_RG_INTEGER' in assertions and a bunch of missing pixel converions cases. Signed-off-by: Ian Romanick <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
* mesa: add missing RG_INTEGER and some RED_INTEGER_EXT checks.Dave Airlie2011-12-101-0/+4
| | | | | | | | | | | This just adds the correct checks and asserts in the right places. This doesn't fix all the tests that I've sent to piglit, need to add int paths to go alongside the uint paths that don't go via float to fix it up properly. I'm not sure how much of that could be templated/shared will have a look once I write it the long way. Reviewed-by: Brian Paul <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

| | | | | | | | | | | | | | | | | The EXT_texture_integer issues says: Should pixel transfer operations be defined for the integer pixel path? RESOLVED: No. Fragment shaders can achieve similar results with more flexibility.
