Fixed bug #611 Comment #22 From Tim Angus 2009-04-02 08:45:52 (-) [reply] ------- First of all, thanks for committing this. Unfortunately it seems the patch has only partially applied to wincommon/SDL_sysevents.c and currently a clean SDL 1.2 checkout doesn't build. The new patch here (http://bugzilla.libsdl.org/attachment.cgi?id=316) fixes this.

.SH "NAME"
SDL_GetRGB \- Get RGB values from a pixel in the specified pixel format\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBvoid \fBSDL_GetRGB\fP\fR(\fBUint32 pixel, SDL_PixelFormat *fmt, Uint8 *r, Uint8 *g, Uint8 *b\fR);
.SH "DESCRIPTION"
.PP
Get RGB component values from a pixel stored in the specified pixel format\&.
.PP
This function uses the entire 8-bit [0\&.\&.255] range when converting color components from pixel formats with less than 8-bits per RGB component (e\&.g\&., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8])\&.
