> which version the change was effective?
Not exactly. We have a change-log entry for HDRI at 6.3.4-0 so we suspect somewhere around that time. You can always check subversion, module magick/signature.c for change dates. _______________________________________________ Magick-developers mailing list Magick-developers@imagemagick.org http://studio.imagemagick.org/mailman/listinfo/magick-developers
