From 7554b83a21bd62b20df5a7327b69f08108ac9ab6 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 13 May 2010 14:48:13 -0700 Subject: [PATCH] intel: Handle arbitrary compressed formats in intel_compressed_num_bytes. Note that we don't support arbitrary block size for compressed quite yet -- block height of 4 is hard-coded all over the place. Bug #27098 (srgb dxt1 producing a bytes per pixel of 0). --- src/mesa/drivers/dri/intel/intel_tex_format.c | 27 ++++++------------- 1 file changed, 8 insertions(+), 19 deletions(-) diff --git a/src/mesa/drivers/dri/intel/intel_tex_format.c b/src/mesa/drivers/dri/intel/intel_tex_format.c index 7be5231eaef..610a169beb2 100644 --- a/src/mesa/drivers/dri/intel/intel_tex_format.c +++ b/src/mesa/drivers/dri/intel/intel_tex_format.c @@ -1,7 +1,7 @@ #include "intel_context.h" #include "intel_tex.h" #include "main/enums.h" - +#include "main/formats.h" /** * Choose hardware texture format given the user's glTexImage parameters. @@ -208,22 +208,11 @@ intelChooseTextureFormat(GLcontext * ctx, GLint internalFormat, int intel_compressed_num_bytes(GLuint mesaFormat) { - int bytes = 0; - switch(mesaFormat) { - - case MESA_FORMAT_RGB_FXT1: - case MESA_FORMAT_RGBA_FXT1: - case MESA_FORMAT_RGB_DXT1: - case MESA_FORMAT_RGBA_DXT1: - bytes = 2; - break; - - case MESA_FORMAT_RGBA_DXT3: - case MESA_FORMAT_RGBA_DXT5: - bytes = 4; - default: - break; - } - - return bytes; + GLuint bw, bh; + GLuint block_size; + + block_size = _mesa_get_format_bytes(mesaFormat); + _mesa_get_format_block_size(mesaFormat, &bw, &bh); + + return block_size / bh; } -- 2.30.2
