TIFFTAG_ROWSPERSTRIP is still limited to 32-bits. However, tags which return file offsets or object sizes are necessarily 64-bits. These tags are 64-bits: TIFFTAG_STRIPOFFSETS TIFFTAG_STRIPBYTECOUNTS TIFFTAG_FREEOFFSETS TIFFTAG_FREEBYTECOUNTS TIFFTAG_TILEOFFSETS TIFFTAG_TILEBYTECOUNTS Bob -- Bob Friesenhahn bfriesen@simple.dallas.tx.us, http://www.simplesystems.org/users/bfriesen/ GraphicsMagick Maintainer, http://www.GraphicsMagick.org/
