They in turn call 34 * device driver functions which actually copy/convert/store the user's 35 * texture image data. 36 * 37 * However, most device drivers will be able to use the fallback functions 38 * in this file. That is, most drivers will have the following bit of 39 * code: 40 * ctx->Driver.TexImage1D = _mesa_store_teximage1d; 41 * ctx->Driver.TexImage2D = _mesa_store_teximage2d; 42 * ctx->Driver.TexImage3D = _mesa_store_teximage3d; 43 * etc... 44 * 45 * Texture image processing is actually kind of complicated. We have to do: 46 * Format/type conversions 47 * pixel unpacking 48 * pixel transfer (scale, bais, lookup, etc) 49 * 50 * These functions can handle most everything, including processing full 51 * images and sub-images. 52 */ 53 54 55#include "glheader.h" 56#include "bufferobj.h" 57#include "colormac.h" 58#include "image.h" 59#include "macros.h" 60#include "mipmap.h" 61#include "mfeatures.h" 62#include "mtypes.h" 63#include "pack.h" 64#include "pbo.h" 65#include "imports.h" 66#include "texcompress.h" 67#include "texcompress_fxt1.h" 68#include "texcompress_rgtc.h" 69#include "texcompress_s3tc.h" 70#include "teximage.h" 71#include "texstore.h" 72#include "enums.h" 73#include "../../gallium/auxiliary/util/u_format_rgb9e5.h" 74#include "../../gallium/auxiliary/util/u_format_r11g11b10f.h" 75 76 77enum { 78 ZERO = 4, 79 ONE = 5 80};
