ofxFontSampler is a TrueType Font (TTF) glyph path extractor and renderer designed to finely sample glyphes from a font.
It was somewhat inspired by Ken Perlin's blog post "Unfont Design".
The project consist of two parts :
- FontSampler, a TrueType Font (TTF) file parser and a glyph path extractor designed to handle type 4 CMAP format and working as a standalone c++ library.
- ofxFontSampler, an openframework addons interfacing with FontSampler.
The example consists of two demos you can switch using the mouse left-click. It relies on the ofxTriangleMesh addon to triangulate meshes.
Display iteratively the 26 uppercase letters of the latin charset (A to Z) with different animated contour sampling.
Display a 3d text with dynamic extrusion on the z-axis using the ofxRenderFont utility class.
- FontSampler is intended to be used at the glyph (ie. character) level, you can certainly write text with it but no support is given.
- It was designed to handle TTF using type 4 CMAP (cf. TrueType Reference). Most TrueType fonts support it, but some don't.
- Composites glyphes, like letters with accent (eg. "é"), are not supported.
- It is more of a working prototype which would need work on the memory management side to be production ready.
