SVG generation gem?
in [Ruby]
|
From: Rick DeNatale on 30 Jul 2010 11:59 I've recently started playing with an Epilog laser cutter, and I find myself wanting to programmatically generate SVG files. I googled for ruby and svg this morning and although there seem to be a few old stagnant efforts, there's nothing too useful I could find. I suppose it wouldn't be too hard to start cooking something up using Jim Wierich's xml builder gem, but before I got started I wanted to see if there was anything I missed. -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Github: http://github.com/rubyredrick Twitter: @RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale

I was looking specifically to generate graphs from log data and found a passable library but I don't think it's still active and it is a bit of a pain. It is working for my very specific and not too important needs, but I'd probably go from scratch if it were important or needed to be flexible. -- "Hey brother Christian with your high and mighty errand, Your actions speak so loud, I cant hear a word youre saying." -Greg Graffin (Bad Religion)

Topher Cyll's book, "Practical Ruby Projects; Ideas for the Eclectic Programmer", has a chapter that generates animations with SVG. SVG is wrapped in an SVGObject class but it is only developed to the extent needed for the example project. It may give you a start. See http://www.cyll.org/

SVGPath was a fun try to go further, allowing to build step-by-step a path. I wanted to add animations which could be rendered using either <animate> tags or JS. I would enjoy to improve it and/or collaborate. Please say me if this could be a start for what you are looking for. Regards, B.D.

The graphics models for pdf and svg seem to be quite similar, not surprising given Adobe's major input to SVG. I tend to see both as a declarative expression of the Postscript drawing model, or at least starting there. I notice that there's at least one Prawn svg 'renderer' out there, but it goes in the opposite direction I'm pursuing in that it renders svg into prawn calls, rather than generating SVG from the prawn document model. I haven't investigated any of this really deeply, but it may be possible to write something which extends and reuses most of Prawn but with a different class of Document and some associated classes which render SVG rather than PDF. Perhaps Gregory Brown or one of the other core Prawn contributors will see this and comment? -- Rick DeNatale Blog: http://talklikeaduck.denhaven2.com/ Github: http://github.com/rubyredrick Twitter: @RickDeNatale WWR: http://www.workingwithrails.com/person/9021-rick-denatale LinkedIn: http://www.linkedin.com/in/rickdenatale |
