# pebble-misc # pebble-misc
This repo will be my dumping ground for misc. Pebble stuff. This repo is my dumping ground for miscellaneous Pebble stuff. Please see the `.md` files in each folder for explanations on what everything is for.
Currently, it houses a printable template for hand-drawing Pebble watchfaces. The only watch from the template that I physically own right now is Chalk, so please verify the sizes are correct for the other models before trusting them.

# Fonts
## BDF Font Scaling
BDF fonts do not scale traditionally. In order to scale the fonts in this folder, use the `scale_bdf.py` script in the `tools` folder within this repo. It will output integer-scaled versions of these bitmap fonts.
## BDF Font Editing
The `.toml` files in this folder are for use in the [bited](https://github.com/molarmanful/bited) font editor. Open the corresponding `.bdf` and the resources in the `.toml` will be loaded automatically.
