commit b95de4e9e1bfa27c0f6dbf794da0a38896b2ef8b Author: Eric Anholt Date: Wed Dec 9 10:08:07 2009 -0800 mesa: Move OES_read_format support from drivers into the core. The assertion is that the correct read type to be using is the native read type of the underlying read renderbuffer. For some fallback paths, this may be worse than GL_RGBA/GL_UNSIGNED_BYTE for reads today, but it gets all drivers the expected GL_BGRA/GL_UNSIGNED_BYTE for ARGB8888 or GL_BGR//GL_UNSIGNED_SHORT_5_6_5_REV for rgb565 with no work. diff --git a/src/mesa/main/context.c b/src/mesa/main/context.c index 03fc57e..5c20ce0 100644 --- a/src/mesa/main/context.c +++ b/src/mesa/main/context.c @@ -564,10 +564,6 @@ _mesa_init_constants(GLcontext *ctx) /* GL_ARB_draw_buffers */ ctx->Const.MaxDrawBuffers = MAX_DRAW_BUFFERS; - /* GL_OES_read_format */ - ctx->Const.ColorReadFormat = GL_RGBA; - ctx->Const.ColorReadType = GL_UNSIGNED_BYTE; - #if FEATURE_EXT_framebuffer_object ctx->Const.MaxColorAttachments = MAX_COLOR_ATTACHMENTS; ctx->Const.MaxRenderbufferSize = MAX_WIDTH; diff --git a/src/mesa/main/framebuffer.c b/src/mesa/main/framebuffer.c index 154deda..d958dbf 100644 --- a/src/mesa/main/framebuffer.c +++ b/src/mesa/main/framebuffer.c @@ -969,3 +969,29 @@ _mesa_dest_buffer_exists(GLcontext *ctx, GLenum format) /* OK */ return GL_TRUE; } + +GLenum +_mesa_get_color_read_format(GLcontext *ctx) +{ + switch (ctx->ReadBuffer->_ColorReadBuffer->Format) { + case MESA_FORMAT_ARGB8888: + return GL_BGRA; + case MESA_FORMAT_RGB565: + return GL_BGR; + default: + return GL_RGBA; + } +} + +GLenum +_mesa_get_color_read_type(GLcontext *ctx) +{ + switch (ctx->ReadBuffer->_ColorReadBuffer->Format) { + case MESA_FORMAT_ARGB8888: + return GL_UNSIGNED_BYTE; + case MESA_FORMAT_RGB565: + return GL_UNSIGNED_SHORT_5_6_5_REV; + default: + return GL_UNSIGNED_BYTE; + } +} diff --git a/src/mesa/main/framebuffer.h b/src/mesa/main/framebuffer.h index 45a4703..ef21dd9 100644 --- a/src/mesa/main/framebuffer.h +++ b/src/mesa/main/framebuffer.h @@ -81,5 +81,10 @@ _mesa_source_buffer_exists(GLcontext *ctx, GLenum format); extern GLboolean _mesa_dest_buffer_exists(GLcontext *ctx, GLenum format); +extern GLenum +_mesa_get_color_read_type(GLcontext *ctx); + +extern GLenum +_mesa_get_color_read_format(GLcontext *ctx); #endif /* FRAMEBUFFER_H */ diff --git a/src/mesa/main/get.c b/src/mesa/main/get.c index e8932f8..3d32649 100644 --- a/src/mesa/main/get.c +++ b/src/mesa/main/get.c @@ -13,6 +13,7 @@ #include "mtypes.h" #include "state.h" #include "texcompress.h" +#include "framebuffer.h" #define FLOAT_TO_BOOLEAN(X) ( (X) ?
