Date: Mon, 31 Oct 2005 14:23:34 +0100 From: Thomas Omilian <paccy@arcor.de> To: sdl@libsdl.org 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
