I’ve been adding example code to PDF::Cairo. Here’s the output from what I’ve got so far:
Box-slicing test, not actually useful for anything.
Image-loading test, ditto. (new! improved! fixed translate/rotate/scale order to get rid of skew)
Inkle drafting grid, planning tool for Inkle weaving. Reimplemented from here, using my Box library and polygons rather than my hand-tuned, impossible-to-debug component method. About 12x larger output, but Cairo isn’t a PDF library, it’s a library that can output PDF, so you don’t get as close to the metal.
Isometric drawing pad, mixes my Box library with a bit of trig to clean up the grid layout.
Kanji practice sheet, currently blank; I plan to add a second example that fills it in with selected characters in a pen font, grayed-out so you can draw on top of them. It’ll be much cleaner than the version I wrote ~14 years ago.
Sample Pango layout, showing the use of its markup. Now includes glyph outline support.
NEW! Glyph outlines, including manually processing the drawing operators.
New! Traveller hex grid. Unlike my 15-year-old sec2pdf script, which I threw together over a weekend when I discovered how terrible the existing Traveller mapping tools were, this one actually centers the grid correctly on the page. (seriously, before sec2pdf, the way to create a PDF Traveller map was to run a DOS program that spat out an import script for an obscure 2D free CAD program, then let it run for 10-20 minutes; these days it’s a lot better, although the border definition method I came up with is still in use)
