In article <617@adobe.UUCP>, greid@adobe (Glenn Reid) writes: I still believe that it is related to numeric round-off, `but perhaps the roundoff is happening in the interpreter rather than `being inherent in the source program. ` Maybe this helps: The errors disappear if an extra translate of .5 pixel is specified in the program. It looks like the pixel painting software is not rounding but truncating pixel coordinates. -- Piet van Oostrum, Dept of Computer Science, University of Utrecht Padualaan 14, P.O.
