# octofont

```ttf-to-textfont``` will convert a TrueType font into a 'textfont' file, which is a simple text file describing a bitmapped font.

```textfont-to-octo``` will convert the textfont file into [Octo](http://johnearnest.github.io/Octo/) assembly code.

An intermediate file is used so that the font can be hand edited before the final conversion.

This is a hacked-up work in progress. To get full functionality, you will need to edit the source code. ```textfont-to-octo``` is

especially rough. Currently limited to 8x8px or smaller glyphs.

Many improvements could be made:

 - Handling of larger glyphs, using multiple sprite ops and/or 16-bit SuperChip sprites

 - A sparse mode with a glyph location lookup table to avoid lots of 0s

 - A fixed width mode without a width table

 - Variable height glyphs

 - Optional output of sample test code

 - Additional functions, such as drawing a string

 - Advanced kerning rules

 - Optional guards for out-of-bounds inputs

 - Better handling of vertical alignment and the font baseline. Clipping the glyphs with a bounding box is not helping with this.

 - Use of register aliases
