Some weeks ago Deri James sent me a first implementation of a gropdf driver; I've uploaded it temporarily to http://groff.ffii.org/groff/gropdf/ Deri writes: [...] Its drawback is its written in perl and has a dependancy on perl module Compress::Zlib (to do the Flate compression). However, despite this, you may consider it useful to have a 'native' PDF driver for groff (rather than the PS -> ghostscript route). It is slower than grops but faster than grops+gs. The archive contains bin/gropdf (which should be installed in the same directory as 'grops'), /devpdf which should be installed in your groff font directory, two files for the /tmac directory, and an /examples directory. NOTE: Lines 13-15 of 'gropdf' must be "hand edited" to configure for your particular 'groff' setup. Of course these paths would normally be inserted by an install script. The /devpdf directory includes the .pfa fonts required to supplement the 14 PDF type 1 base fonts up to the standard 35 fonts which PostScript uses. Gropdf supports the following run switches:- -p <papersize> (same as grops) -l (landscape mode - NOT WORKING yet!!) -d (debug mode - uncompressed PDF and troff output included as comments) -F <path to 'font' directory (same as grops TO DO Fix landscape. Support PSPIC (and new PDFPIC). Support some of the more common 'x ps:' commands (particularly page rotation and pdf bookmarks). There are a few troff commands not handled yet (most notably 'Da' (Draw Arc) since I have not yet figured out a good way to convert to Bezier Curves for PDF!). Improve some of the algorithms used in PDF generation (unnecessary context switches between GFX and text modes). Possibly implement Type 1c font subsetting to reduce file sizes (also, current implementation restricted to first 256 glyphs per font). Fix bugs!! Hope you enjoy it. Please test this! I haven't found time yet to evaluate it. Werner
