How to specify image resolution in pixels?

Questions
1

With Typst is possible to create images for a certain resolution specified in pixels?
(as I noticed the lengths do not include pixels), what I have been doing is specifying the page size in mm then using the png export function with a specific ppi to target that resolution.

I mainly want to do this so my fonts are pixel perfect, and with this is it possible to use a bitmap font or similar (a .bdf font) - which are designed to be at certain pt sizes?

Maybe the easiest math is available if you specify the page size in pt. There is a fixed conversion of 1in = 72pt so then it’s easy to export with the correct ppi setting.

For example:

  • 144 ppi => 1 pt == 2 pixels
  • 288 ppi => 1 pt == 4 pixels

Any unit would work, you just have to figure out the integer valued conversion factors, but points is probably the easiest one because output resolution is measured in ppi.

Typst only supports OTF and TTF fonts, so I don’t think that will be possible. At least it’s not implemented yet, unless you can convert the fonts to a format Typst supports.
