Fixed bug #831 Andrey 2009-10-09 08:08:04 PDT gapi_hires_fix I made a mistake with the conclusions. And last time I as was mistaken with conclusions. Now I thought about in more detail the algorithm works. I have made it that the project fheroes2 well worked. The result of my work in attachment. I have a possibility to check up it on different models pocketpc. I checked various modes screen of 320x320, 320x240, 640x480, 800x400.

.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)\&.
