From the ARB_internalformat_query2 specification:
"- IMAGE_TEXEL_SIZE: The size of a texel when the resource when used as
an image texture is returned in <params>. This is the value from the
/Size/ column in Table 3.22. If the resource is not supported for image
textures, or if image textures are not supported, zero is returned.
- IMAGE_COMPATIBILITY_CLASS: The compatibility class of the resource when
used as an image texture is returned in <params>. This corresponds to
the value from the /Class/ column in Table 3.22. The possible values
returned are IMAGE_CLASS_4_X_32, IMAGE_CLASS_2_X_32, IMAGE_CLASS_1_X_32,
IMAGE_CLASS_4_X_16, IMAGE_CLASS_2_X_16, IMAGE_CLASS_1_X_16,
IMAGE_CLASS_4_X_8, IMAGE_CLASS_2_X_8, IMAGE_CLASS_1_X_8,
IMAGE_CLASS_11_11_10, and IMAGE_CLASS_10_10_10_2, which correspond to
the 4x32, 2x32, 1x32, 4x16, 2x16, 1x16, 4x8, 2x8, 1x8, the class
(a) 11/11/10 packed floating-point format, and the class (b)
10/10/10/2 packed formats, respectively.
If the resource is not supported for image textures, or if image
textures are not supported, NONE is returned.
- IMAGE_PIXEL_FORMAT: The pixel format of the resource when used as an
image texture is returned in <params>. This is the value
from the /Pixel format/ column in Table 3.22. If the resource is not
supported for image textures, or if image textures are not supported,
NONE is returned.
- IMAGE_PIXEL_TYPE: The pixel type of the resource when used as an
image texture is returned in <params>. This is the value from
the /Pixel type/ column in Table 3.22. If the resource is not supported
for image textures, or if image textures are not supported, NONE is
returned."

File: docs/README.WIN32 Last updated: 21 June 2013 Quick Start ----- ----- Windows drivers are build with SCons. Makefiles or Visual Studio projects are no longer shipped or supported. Run scons libgl-gdi to build gallium based GDI driver. This will work both with MSVS or Mingw. Windows Drivers ------- ------- At this time, only the gallium GDI driver is known to work. Source code also exists in the tree for other drivers in src/mesa/drivers/windows, but the status of this code is unknown. Recipe ------ Building on windows requires several open-source packages. These are steps that work as of this writing. - install python 2.7 - install scons (latest) - install mingw, flex, and bison - install pywin32 from here: http://www.lfd.uci.edu/~gohlke/pythonlibs get pywin32-218.4.win-amd64-py2.7.exe - install git - download mesa from git see http://www.mesa3d.org/repository.html - run scons General ------- After building, you can copy the above DLL files to a place in your PATH such as $SystemRoot/SYSTEM32. If you don't like putting things in a system directory, place them in the same directory as the executable(s). Be careful about accidentially overwriting files of the same name in the SYSTEM32 directory. The DLL files are built so that the external entry points use the stdcall calling convention. Static LIB files are not built. The LIB files that are built with are the linker import files associated with the DLL files. The si-glu sources are used to build the GLU libs. This was done mainly to get the better tessellator code. If you have a Windows-related build problem or question, please post to the mesa-dev or mesa-users list.
