Make sure "print '-SX,Y' ..." doesn't round down a pixel. Bug # 35307. The eps output from gnuplot and gl2ps each specify whole numbrer bboxs. Modify ghostscript's resolution to ensure output size is correct. Also adjust fontisize to compenstate for resolution change. * __print_parse_opts__.m: Set ghostscript resolution to 72 to ensure all bboxs have whole numbers. Add a scalefontsize variable to enable fontsize to be compensated for change in resolution. * print.m: Modify fontsize property value to compensate for change in ghostscript resolution. * __gnuplot_drawnow__.m: Increase precision for specified canvas size.
