# Skrivañ
|
|
|
|
This is:
|
|
* a CLI tool to render a subset of a TTF/OTF/AAT font to PNG, and produce a custom-format character-to-positions map;
|
|
* a lightweight crate to load such a map and render text to textures (or just iterate on glyphs and let you do the rendering).
|
|
|
|
Ideal for making a lightweight 2D game. All the hard work and big dependencies are done before compiling the game. No TTF to include, only an image and a small binary file. Rendering text is simply associating characters to positions on the font texture, like a tilemap. Glyphs can be fed to a vertex shader easily.
|
|
|
|
Not yet features:
|
|
* alignment (currently only left alignment is supported)
|
|
* wordwrap
|
|
|
|
Not planned:
|
|
* Smart kerning algorithms, hyphenation, and other LaTeX-grade stuff.
|
|
* Subpixel antialiasing (antialiasing is computed only for the base texture, not when rendering text)
|
|
|
|
Similar tools already exist, but:
|
|
* the best ones, like harfbuzz, are quite heavy (we use harfbuzz for rendering).
|
|
* the lightest ones are made for embedded or Gameboy.
|
|
* other ones need the TTF at runtime.
