Fixed bug #89 Date: Sun, 23 Oct 2005 16:39:03 +0200 From: "A. Schmid" <sahib@phreaker.net> Subject: [SDL] no software surfaces with svgalib driver? Hi, I noticed that the SDL (1.2.9) svgalib driver only makes use of linear addressable (framebuffer) video modes. On older systems (like one of mine), linear addressable modes are often not available. Especially for cards with VESA VBE < 2.0 the svgalib vesa driver is unusable, since VESA only supports framebuffering for VBE 2.0 and later. The changes necessary to add support for software surfaces seem to be relatively small. I only had to hack src/video/svga/SDL_svgavideo.c (see attached patch). The code worked fine for me, but it is no more than a proof of concept and should be reviewed (probably has a memory leak when switching modes). It also uses the vgagl library (included in the svgalib package) and needs to be linked against it. -Alex

.SH "NAME"
SDL_SetClipRect\- Sets the clipping rectangle for a surface\&.
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBvoid \fBSDL_SetClipRect\fP\fR(\fBSDL_Surface *surface, SDL_Rect *rect\fR);
.SH "DESCRIPTION"
.PP
Sets the clipping rectangle for a surface\&. When this surface is the destination of a blit, only the area within the clip rectangle will be drawn into\&.
.PP
The rectangle pointed to by \fBrect\fR will be clipped to the edges of the surface so that the clip rectangle for a surface can never fall outside the edges of the surface\&.
.PP
If \fBrect\fR is \fBNULL\fP the clipping rectangle will be set to the full size of the surface\&.
