Subject: [SDL] SDL_SoftStretch() fixed!
Ok, after debugging the night I found the error:
in video/SDL_stretch.c in Line 81
/* See if we need to regenerate the copy buffer */
if ( (src_w == last.src_w) &&
(dst_w == last.src_w) && (bpp == last.bpp) ) {
return(0);
}
the second comparison should be (dst_w == last dst_w).
Perhaps someone could apply it to the source...
Regards,
Thomas Omilian
