* undo some accidental changes in _mesa_is_legal_format_and_type()Brian Paul2006-09-111-4/+7
|
* Redefine the BYTE_TO_FLOAT() and SHORT_TO_FLOAT() macros to avoid problemsBrian Paul2006-09-101-4/+20
| | | | | | 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.
* misc clean-upsBrian Paul2006-05-071-35/+38

* check for float->uint overflow in _mesa_unpack_depth_span()Brian Paul2006-05-051-3/+16

|
* Bug 4996.Brian Paul2005-11-091-27/+28
| | | | | Replace use of FLOAT_TO_USHORT with either CLAMPED_FLOAT_TO_USHORT or UNCLAMPED_FLOAT_TO_USHORT. Same should be done for UBYTE, UINT, etc.
* added _mesa_pack_depth_stencil_span()Brian Paul2005-10-011-0/+47
|
* Initial work for GL_EXT_packed_depth_stencil extension.Brian Paul2005-09-281-34/+114
| | | | glReadPixels done, glDrawPixels mostly done.
* remove DEFARRAY, CHECKARRAY stuffBrian Paul2005-09-061-21/+6
|
* silence a variety of warnings found with g++ 3.4.2Brian Paul2004-12-031-2/+2
|
* GL_(UN)PACK_SKIP_IMAGES should only be applied to 3D texture pack/unpackingBrian Paul2004-11-101-24/+67
| | | | | | | and ignored for 1D and 2D images. Need to pass in image dimensions (1,2,3) to the _mesa_image_address() function. This change gets propogated to some other routines. Also added new _mesa_image_address[123]d() convenience functions.
* added a comment and assertion in _mesa_clip_drawpixels() for PixelZoomBrian Paul2004-11-091-0/+3
|
* added _mesa_clip_drawpixels() and _mesa_clip_readpixels()Brian Paul2004-11-091-1/+97
|
* Use the _mesa_scale_and_bias_rgba() function in the convolution functions.Brian Paul2004-10-311-5/+5
| | | | Minor clean-ups.
* fix a commentBrian Paul2004-10-021-2/+2

* Silence gcc 3.4 warnings on ReactOS. Mostly unused var warnings. (patch ↵Brian Paul2004-08-251-0/+2

* GL_BGR can't be used with the packed types, according to the GL spec. ↵Brian Paul2004-05-121-1/+15
| | | | Enforce such.
* some component ordering bugs in extract_float_rgba()Brian Paul2004-05-121-24/+32
|
* New glTexImage code.Brian Paul2004-04-221-41/+46
| | | | | | | | The gl_texture_format struct now has a StoreTexImageFunc that's called by glTex[Sub]Image[123]D to convert the user's texture data into the specific texture format layout. Now it's much easier to add new texture formats (like the 16/32-bit floating point formats). The texutil.[ch] and texutil_tmp.h files are obsolete.
* Implementation of GL_EXT_pixel_buffer_object extension.Brian Paul2004-03-131-26/+8
| | | | | Note: extension may not be finalized yet - subject to change! Note: implementation not fully suitable for h/w implementation yet.
* Remove clamp parameter from _mesa_unpack_color_span_float(). Pass theBrian Paul2004-02-281-19/+13
| | | | | | IMAGE_CLAMP_BIT if needed. Added ClampVertexColors and ClampFragmentColors to GLcontext in anticipation of upcoming extensions (not fully used yet).

* Header file clean-up:Brian Paul2002-10-241-8/+2
| | | | | | | | 1. Remove all.h and PC_HEADER junk. 2. Rolled mem.c and mem.h into imports.c and imports.h 3. Include imports.h instead of mem.h Restore _mesa_create/initialize_context() to be like they were in 4.0.4 New wrappers for a few std C functions: _mesa_atoi(), _mesa_strstr(), etc.
