From 25c8a112abf4bbf271c6972f7539ca2a1c7683bd Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Mon, 28 Nov 2011 11:08:01 -0700 Subject: [PATCH] mesa: access pixels as GLushort in unpack_SL8() Per the format comments and the texstore code, use a GLushort to access the pixel. The code was OK as-is on little endian machines. --- src/mesa/main/format_unpack.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/mesa/main/format_unpack.c b/src/mesa/main/format_unpack.c index 0ab6940144b..0411f5fb740 100644 --- a/src/mesa/main/format_unpack.c +++ b/src/mesa/main/format_unpack.c @@ -749,13 +749,13 @@ unpack_SL8(const void *src, GLfloat dst[][4], GLuint n) static void unpack_SLA8(const void *src, GLfloat dst[][4], GLuint n) { - const GLubyte *s = (const GLubyte *) src; + const GLushort *s = (const GLushort *) src; GLuint i; for (i = 0; i < n; i++) { dst[i][RCOMP] = dst[i][GCOMP] = - dst[i][BCOMP] = nonlinear_to_linear(s[i*2+0]); - dst[i][ACOMP] = UBYTE_TO_FLOAT(s[i*2+1]); /* linear! */ + dst[i][BCOMP] = nonlinear_to_linear(s[i] & 0xff); + dst[i][ACOMP] = UBYTE_TO_FLOAT(s[i] >> 8); /* linear! */ } } -- 2.30.2
