d3 export demo
This is a proof-of-concept demo for saving d3js graphics as PDF/PNG/SVG files.
Objective
CGI takes incoming SVG serialization. Use graphics toolkit to open SVG serialization as input, output PNG or PDF as output.
This perl implementation just performs a system call on rsvg-convert, nothing
specific to perl.
Options
- librsvg
- imagemagick http://stackoverflow.com/questions/15119679/converting-an-svg-with-imagemagick
- batik
See http://stackoverflow.com/questions/4809194/convert-svg-image-to-png-with-php
for another nice overview.
We just run rsvg-convert man rsvg
