Fontsy

With the release of Bitsy 5 came a brand-new font system. The new system is far more customizable than the old one: among other features, it includes a spec for a .bitsyfont format which can be used to make custom fonts.

Since the format is plaintext, it's relatively easy to make custom fonts by typing them out in a text editor, but from a creative perspective, it's a bit hard to draw characters that way. To help with this, Fontsy provides a way to convert back-and-forth between .bitsyfont and .bitsyfont.png files, which can be used to draw fonts in a more traditional image editor.

Notes:

• The default bitsy font is imported by default
• Fontsy doesn't save anything; make sure to export your work!
• Font data is 1-bit (i.e. black and white)
• The images used for the old custom font hack are not compatible with Fontsy
• If you're using the built-in editor, keep the export section closed to improve performance
• Hover over characters in built-in editor to see code points

Recommended workflow:

1. Pick an existing font to use as a base (e.g. the default bitsy font, or one of the others included in the bitsy editor)
2. Import .bitsyfont file
3. If needed, make minor edits using the built-in editor (e.g. changing size, name, or adding characters)
4. Export .bitsyfont.png image
5. Open image in external editor and customize font (note: make sure not to edit the borders, and to export in a mode which doesn't affect colours)
6. Import edited .bitsyfont.png image
7. Export .bitsyfont file
