Inkscape¶
- Inkscape commandline: https://inkscape.org/sk/doc/inkscape-man.html
- inkscape kann mit --shell gestartet werden - dann ist es evtl. noch schneller. Aktuell hat ein A4 svg skaliert nach 200px 3 Sekunden gebraucht
inkscape %%x -z --export-dpi=500 --export-area-drawing --export-png="%%~nx.png"
Other¶
- IM soll langsam sein (darum in T3 IM 4.2.9) und laut oberen SO Posting Probleme mit SVG haben.
- http://phpthumb.sourceforge.net/ und basiert auf ImageMagick. Besser waere GraphicsMagick.
