Use cases? #2

Could you list one or more use cases for this tool? What can we do with such a Canvas object in Node?

Good Question! I want to use it to render small clippings from a giant svg (build from polygons, -lines and text stored in a database) to multiple raster image formats in a batch job. GraphicsMagick or Cairo doesn't feel right to me because i want to get the same results as I would get in browser. A Browser in contrasr makes perfect SVG to PNG conversation with perfect text support. And with nodejs I am more flexible to put logic into the creation process than with Illustrator or Inkscape (no need to say that its hard to connect Illustrator to a database)

Do you have some ideas?

Ah yes, I see. That's a great use case. PNG fallback of SVG for IE8 will be needed for a few more years. Grunticon is a popular Node tool that provides automated SVG-to-PNG conversations. From what I see, it uses the "svg-to-png" package which in turn uses "phantomjs". Not sure how your tool stacks up against Grunticon in terms of conversion quality. Might be worth checking out.
