migrate to diagrams-raster from diagrams-svg

[cartazio]

even aside from the rendering issue i'm having with svg, having a 10mb-100mb svg is a bit nasty!

i may have a go at this task if you'd be open to it

What is diagrams-raster?

[cartazio]

i mean https://github.com/diagrams/diagrams-rasterific its a diagrams backend that uses rasterific, and thence juicy-pixels to emit a png/jpeg/gif etc.

i may just try doing the migration speculatively, the motivation being that for high complexity visuals, a raster image tends to have MUCH better space complexity than a vector format

Only reason I was just using SVG is that the gtk libraries are often a pain to install on OSX so I wanted to avoid that. What's the situation with rasterific on that?

[edsko]

Could we make it conditional? This is an executable after all, should be okay?

[cartazio]

rasterific has no system deps, pure haskell al the way. from vector raster rendering to generating the final file https://hackage.haskell.org/package/Rasterific

sure, making it conditional would be ok by me,

[edsko]

If it's pure haskell, go for it :)

Closing this as it's not strictly speaking an issue. If you ever get round to implementing this, feel free to open a pull request :)

sounds good
