In version 10342, 'scourage' added the CMP_scale.c using IMB_scaleImBuf(), while in the same version 'scourage' added the scalefast_compbuf() in CMP_util.c. What's the difference between them? And should there be a unique way to scale the CompBuf? This question is probably prepared for 'scourage'. Thanks, -- James Ruan
