I hadn't checked until you asked but had assumed that the difference was the due to the underlying jpeg library called by readimg having changed from WinXP to Win7. The following check is pretty rough and ready but seems to bear out my assumption: == Ubuntu 9.04 +/+/ rgbmat_pplatimg_ jpg1 _3.16861e12 +/+/ jpg2 _3.16861e12 == Windows7 +/+/ rgbmat_pplatimg_ jpg1 _3.16861e12 +/+/ jpg2 _3.16853e12 ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
