This is only relevant to file plug-ins. It didn't occur to me that they would ever be written in anything except C, but if that is a reasonable possibility, then I accept the argument.

The orientation is *always* supposed to be set to "top-left" when an image is saved, on the principle that after the user has edited the image in GIMP, the orientation is the way the user wants it. Only a camera should ever set it to anything other than "top-left". -- Bill ______________ ______________ ______________ ______________ Sent via the CNPRC Email system at primate.ucdavis.edu
