Hi, Updated patches for SVG stringwidth (using AFM files) and support for EPS output.
3 patches, #3 depends on #1 as EPS uses AFM for stringwidth too. 1) http://www.vitality.dk/rrdtool/patches/2002-04-06-svg2.diff src/rrd_afm.[ch], src/rrd_afm_data.[ch] and changes to rrd_gfx.[ch] to use AFM for stringwidth in SVG output. 2) http://www.vitality.dk/rrdtool/patches/2002-04-06-libafm.diff Creates libraries/afm with .afm files for the standard 14 postscript fonts and perl script to create src/rrd_afm_data.c Includes small test program to show examples of calculated stringwidth and actual stringwidth. 3) http://www.vitality.dk/rrdtool/patches/2002-04-06-eps.diff Adds EPS output support. Modifies rrd_tool.c as rrd_graph() changes the argv pointer, and rrd_tool then always wrote the 200x100 output line to the file (which probably doesn't do anything for png images, but eps files fail having it after the %%EOF marker). I've started looking at PDF, but it will take some time as spring has started and we have a "Night Film Festival" currently. Old text: To reduce runtime overhead for using AFM files I have chosen to encode them as constant C globals instead of parsing the files at runtime. This is done by the perl script compile_afm.pl which parses the afm files and generates src/rrd_afm_data.c The format is documented in rrd_afm_data.h All the font data and the perl script are stored in a new directory: libraries/afm. Adobe allows distribution and modification of the *.afm files as long as the copyright message is not changed. The files have the generic afm names: rrd_afm.h/c and rrd_afm_data.h/c as the afm font info will be useful for implementing EPS/PDF formats as they use the same font metrics. Users can add their own fonts, run the perl script and recompile rrdtool. The included set of fonts are required by all postscript (like) devices so users can count on having them in their printer/viewer. I use "Helvetica" as default, so that one should stay, all others can be removed to save space. The perl script uses all the .afm files in the directory. ---- - Peter Speck When the going gets weird, the weird turn pro.
