Date: Thu, 11 May 2006 19:08:05 -0400 From: Mike Frysinger Subject: [SDL] [patch] remove limits.h hack from linux joystick code there is a small hack in the current linux joystick code to work around broken cross-compilers by including more than one limits.h ... at the very least, this is not arm-specific by any means i'm of the opinion that libsdl should not contain such things ... people should be fixing their cross-compilers, not bloating other's source trees patch attached to clean the cruft -mike

.SH "NAME"
SDL_GetRGBA\- Get RGBA values from a pixel in the specified pixel format\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBvoid \fBSDL_GetRGBA\fP\fR(\fBUint32 pixel, SDL_PixelFormat *fmt, Uint8 *r, Uint8 *g, Uint8 *b, Uint8 *a\fR);
.SH "DESCRIPTION"
.PP
Get RGBA 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])\&.
.PP
If the surface has no alpha component, the alpha will be returned as 0xff (100% opaque)\&.
