PostScript backend #200

Open pcwalton opened 5 years ago

pcwalton commented 5 years ago

It would be nice to have a PostScript backend, so that you can construct Pathfinder scenes and then print them. (This has potential Firefox applications.)

Why PostScript as opposed to PDF?

pcwalton commented 5 years ago

Because as I understand it printers take PostScript.

I wrote a small PS exporter. I wonder if the exporters should be moved into their own crate and be added via SceneExt traits?

pcwalton commented 5 years ago

I think that would be a good idea, yeah.

SceneProxy depends on SVG export (and ideally it should also allow PDF and PS). This causes a cyclic crate dependency between renderer and export (the new crate with SVG, PDF and PS export).

pcwalton commented 5 years ago

Yeah, we can just get rid of the SceneProxy Debug implementation.
