Alternatives to Batik for scaling images #9
Description
#6 tries to replace the batik svg to pdf converter with electron's printToPDF. At first glance, things are looking good on that front (ref #6 (comment)),
But, the old image server also uses batik to scale images (from a plotly svg to a scaled png). This gist compares the batik converter with two other node.js libraries (sharp and gm) and a browser-side solution.
The browser-side solution is looking good. It uses context.drawImage's width/height options for png/jpeg/webp formats and viewBox for SVGs.
Can anyone think of possible limitations for the browser-side solution?

I can't think of any problems, and if anything I think browser-side should allow us to do better with the
crispEdgesissues #6 (comment) as it can apply crisp rendering after the image is already scaled up.etpinard commentedon Sep 1, 2017
