Go Tool to convert svg to png/jpg

[will]

Hi Gophers,

Is there a Golang based tool (or library) tool to convert svg to png or jpg?

regards,

Will

I'm looking for one too but can't find anything online either..

There is no cross-platform graphics library included in Go.

Most likely you’ll need a C binding to Qt or similar to perform the rasterization.

You might be able to put one together using something like https://github.com/hajimehoshi/ebiten

Just to be clear: PNG is a description of pixel values comprising an image (RGBa, RGBa, RGBa, ...), SVG is a program for creating an image (set color to blue, draw a circle, change to red, draw a line, ...). Going from SVG (scalable vector graphics) to pixels is to render an image by executing the simple program of graphical operation codes. (As said above)

Solutions depending on situation: most every browser has code to rasterize SVG. Can you invoke one to produce your image? There are numerous free tools to do the same--can you bundle one of those and invoke it as an external program? Cairo can do it. (these are in addition to what you really seem to want, which is a fully Go SVG -> PNG renderer.)

Good luck in your project,

michael

Here’s some partial SVG renderers in Go:

* https://github.com/srwiley/oksvg
* https://github.com/goki/gi (uses srwiley’s rasterx rasteriser, has separate SVG parsing / painting impl).

Cheers,

That rasterx is pretty sweet. Should be pretty easy to create an SVG to PNG module using that.
