From 657436da7ee7a7005e25d90092cd5bda2b7d43bd Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 28 Feb 2014 10:53:59 -0700 Subject: [PATCH] mesa: update packed format layout comments Update the comments for the packed formats to accurately reflect the layout of the bits in the pixel. For example, for the packed format MESA_FORMAT_R8G8B8A8, R is in the least significant position while A is in the most-significant position of the 32-bit word. v2: also fix MESA_FORMAT_A1B5G5R5_UNORM, per Roland. --- src/mesa/main/formats.h | 100 ++++++++++++++++++++-------------------- 1 file changed, 50 insertions(+), 50 deletions(-) diff --git a/src/mesa/main/formats.h b/src/mesa/main/formats.h index 3f44de905b7..3102584b6a0 100644 --- a/src/mesa/main/formats.h +++ b/src/mesa/main/formats.h @@ -339,33 +339,33 @@ typedef enum /* Type P formats */ /* msb <------ TEXEL BITS -----------> lsb */ /* ---- ---- ---- ---- ---- ---- ---- ---- */ -
