chasesan When using SDL_RenderCopyEx, I get a problem on some platforms where the output is offset by +/-1 on other platforms and not on others. I tried it with a center of both 0,0 (and offsetting by width/height) and NULL (for centered). The rotation involved is 90, and/or -90 rotation. The rotation was a constant, no arithmetic was involved when inputting it into SDL_RenderCopyEx. This occurred with 32x32, 24x24, and 16x16 texture sizes. I apologize that I don't have more precise information, as I received the information as a bug report myself. But I have tracked the problem down to here. My program requires pixel perfect alignment on several different platforms, so this is something of a showstopper for me. -- Sylvain It appears the RenderCopyEx is done as expected, this is the red rectangle which is not correctly positionned ! So, here's patch with a 0.5 float increment, like for opengles2, for DrawLines, and also Draw Points. |
