Date: Fri, 20 Aug 2004 08:31:20 +0200 From: "Markus F.X.J. Oberhumer" Subject: [SDL-CVS][patch] add missing SDLCALL to headers the small patch attached below (against current CVS) adds some missing SDLCALL decorations to callback types and arguments. Unfortunately one of these changes breaks your gen{def,exp}.pl scripts which should be changed to use non-greedy regular expression matching...

><P
>Get RGBA component values from a pixel stored in the specified pixel format.</P
><P
>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]).</P
><P
>If the surface has no alpha component, the alpha will be returned as 0xff
(100% opaque).</P
