From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225 Description of problem: Ghostscript using devices psgray and psmono assumes -r72 and scales down the final picture if its larger. psrgb appears to scale correctly. Version-Release number of selected component (if applicable): ghostscript-7.05-32.1 How reproducible: Always Steps to Reproduce: 1. gs -sDEVICE=psgray -sPAPERSIZE=letter -r300 \ -sOutputFile=tiger-gray-300.ps \ /usr/share/ghostscript/*/examples/tiger.ps 2. gs -sDEVICE=psrgb -sPAPERSIZE=letter -r300 \ -sOutputFile=tiger-rgb-300.ps \ /usr/share/ghostscript/*/examples/tiger.ps 3. gv tiger-gray-300.ps 4. gv tiger-rgb-300.ps Actual Results: tiger-rgb-300.ps looks correctly -- I have included it for reference only. tiger-gray-300.ps is scaled down, it occupies lower-right corner of the paper. Expected Results: Both pictures should be similar (save the obvious lack of colors in psgray). Additional info: There is an easy way to correct it. The driver incorrectly adds a "scale" command in each %%PageSetup. I have known this problem for years and always postprocess it through: perl -pe 's/^(.*) scale/% removed $1 scale/' A bug lies in /.ImageRead procedure, in psmono_setup[] in BUILD/ghostscript-7*/src/gdevpsim.c:107 the procedure accepts a resolution from the stack but then it hard-codes 72dpi.
