问题
I would like to render an SVG I've created to a hi-res (600 DPI) PNG. This SVG has filter effects, specifically gaussian blur.
Ideally rendering could be done via the command line.
I know the SVG is renderable because you can open it in Chrome/Chromium and the output I'd like to see is there.
Things I've tried:
Importing to Adobe Illustrator
svg2png
Imagemagick
Inkscape
Other command-line tools and programs I'm forgetting right now. Basically anything you could find with Google.
Current path I'm pursuing but stuck on:
Knowing that Chromium can render the SVG just fine and that it's open-source, I figured I'd download the library Chromium depends on to render SVGs (Skia, https://sites.google.com/site/skiadocs/) and use it to output a PNG. So far I've succeeded in installing Skia and running the very first example. I've found an example that renders an SVG (https://code.google.com/p/skia/source/browse/trunk/samplecode/SampleSVG.cpp?r=875) but haven't successfully run it on my OSX machine with the latest updates to XCode and command-line tools. A modified version of that example (with gyp file) that outputs a PNG would be amazing.
Other ideas that might work:
Getting pixel data from Chrome (how would I do that? A simple screenshot isn't enough because of the resolution of the image. I also want a scriptable, repeatable process.)
Using other graphics library that can render SVG. Maybe this comes from other web browsers, maybe not.
回答1:
This seems to work nicely:
webkit2png -F blue.svg -o rendered
The -F says to generate the Full resolution PNG and no thumbnails, and the -o specified that the output filename will be rendered-full.png.
I have reduced the size so it fits on Stack Overflow, but the command shown actually gives the full-resolution 2880x2880 image.
