Date: Thu, 19 Apr 2001 08:36:54 +0300 From: "Mike Gorchak" <mike@malva.com.ua> Subject: Patches for QNX RtP Here my patch for QNX RtP/Photon for SDL-1.2. Detailed description of my changes: SDL/configure.in: If Photon detected declare define ENABLE_PHOTON. SDL/src/video/SDL_sysvideo.h: Added extern to ph_bootstrap. SDL/src/video/SDL_video.c: Added ph_bootstrap to bootstrap array. SDL/src/video/photon/SDL_ph_events.c: Declare DISABLE_X11 if compiled for Photon. SDL/src/video/photon/SDL_ph_image.c: Fixed segment violation on exit. Please update BUGS file. SDL/src/video/photon/SDL_ph_video.c: 1. Enabling window manager. 2. Added to device capabilities Photon Window Manager functions: SetCaption and IconifyWindow. 3. Renamed X11_bootstrap to ph_bootstrap. 4. Removed SEGFAULT termination of programs if Photon not available. SDL/src/video/photon/SDL_ph_wm.c: 1. Declare DISABLE_X11 if compiled for Photon. 2. Added ph_SetCaption and ph_IconifyWindow code. (Thanks to 'phearbear' for iconify window source). 3. Some stubers for other wm functions. Thanks ! ---------------------------- Mike Gorchak CJSC Malva System Programmer

.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)\&.
