Re: [go-nuts] Go Tool to convert svg to png/jpg

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

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,

Re: [go-nuts] Go Tool to convert svg to png/jpg

2020-01-31 Thread Michael Jones 
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

Re: [go-nuts] Go Tool to convert svg to png/jpg

2020-01-31 Thread robert engels 
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
