…Device It should - insure exact position and dimension of paper (plots,[0,0,1,1,0],[0,1,1,0,0],/norm) on a postscript file whatever the size ratio and landscape/portrait - a better THICKness of lines for PostScript output - no more 'stretching' of Hershey fonts and Symbols as described in commit gnudatalanguage@d6a8e4e - a better default size for landscape PostScript outputs. However: the Hershey fonts and Symbols, while maintaining their shape, may differ from size depending on the paper size (should be harmless for most uses)

…t whatever the PS page size. (compensate defect of the plplot ps driver, most aovious now that the size and position are OK) modified symbols so they appear OK whith THICK lines (butt cap for PS problems). Apparently the Hershey with/heigh character is 1/1.3 in IDL, not 1.2 as I thought. Modofied. AFAIK this makes the PS output identical with IDL.
…e with plplot) now that PS outputs use the -a option.
… - simple C code, and it's almost impossible to get the real PS trandfrmation from plplot anyways as this is hidden in the ps.c driver.
…ow compressed with Ascii85 encoding as IDL does. Many tricks used to externally "insert" postscript code in a file opened by the (modified) plplot ps.c driver. The dirver has been modified to produce a more modern and exact ps file, without rewriting it from scratch.

The failure of test_tic_toc on OSX is due to the difficulty to estimate what should be the Systime() passed. With the new tictoc, more accurate and faster, the current test procedure is bound to fail sometimes. |
