This is a very inefficient implementation: Every time a type 3 font glyph is drawn, we parse its operator stream and execute all the operators therein. We'll want to instead cache the glyphs in bitmaps (at least in most cases), like we do for other fonts. But it's a good first step, and all the coordinate math seems to work in the files I've tested. Good test files from pdfa dataset 0000.zip: - 0000559.pdf page 1 (and 2): Has a non-default font matrix; text appears mirrored if the font matrix isn't handled correctly - 0000425.pdf, page 1: Draws several glyphs in a single run; glyphs overlap if Renderer::render_type3_glyph() ignores the passed-in point - 0000211.pdf, any page: Uses type 3 glyphs for all text. Good perf test (already "reasonably fast") - 0000521.pdf, page 5 (or 7 or or 16): The little red flag in the purple box is a type 3 font glyph, and it's colored (which in part means the first operator is `d0`, while all the other documents above use `d1`) |
