I know there are shifting versions of various transformations, but surely they're all slower than what a simple shifting would be? Or am I missing something? <BR /><BR />I can also fake it with a copy &amp; 3 compositing operations, but it's pretty slow too.</P> Fri, 22 Aug 2008 19:20:22 GMT gol 2008-08-22T19:20:22Z https://community.intel.com/t5/Intel-Integrated-Performance/Shifting-images-CopySubpix/m-p/899237#M12549 <P>Is there something to just shift/copy an image with subpixel accuracy?</P> <P>At first I thought that CopySubpix was what I needed, but it only exists for a limited set of single-plane bitmaps.
