PDF frontend

[pcwalton]

It would be nice to use Pathfinder as the backend for a PDF renderer.

[s3bk]

I might look into that. I have created PDFs in Rust before, so not the worst precondition.

[s3bk]

Oh. I just realize "Pathfinder as a backend for a PDF renderer", not a PDF as a backend for Pathfinder.
Well, now there is one at https://github.com/s3bk/pathfinder/tree/pdf_export

[s3bk]

Okay. I can now convert the Tiger from SVG to PDF and PDF to SVG. PDF Fonts though are a nightmare.
The code lives here.

EDIT: now here

Some PDFs work. I have not figured out how symbol fonts work though.

[asajeffrey]

The symbol fonts might be caused by some fonts (e.g. cmsy) being bitmaps rather than type 1. There are ttf versions, e.g. https://ctan.org/tex-archive/fonts/cm/ps-type1/bakoma/ttf/ I don't know if your TeX installation can be persuaded to use them.

[s3bk]

This is an example. It is a Type1C font (Compact Font Format). Glyph 3 is very much defined and has a valid outline. However I can't get the glyph out of font-kit's Font
font_F3.zip

[s3bk]

I managed to implement Type1 (PostScript, OpenType and CFF), Type2 (CFF) and TrueType (via stb-rusttype) in Rust. Stll has a lot of missing parts, but it can render a few PDFs so far.

Code lives back in the pdf repository

Progress report for those not on matrix:

• PDF integration in demo
• merge my fork back
• fix text transformation

[pcwalton]

We have a PDF frontend now.
