Fonts
Stipple Effect uses the underlying Delta Time
 library to load and display fonts. Thus, the program’s native system fonts, as well as user-defined fonts uploaded for use by the text tool at runtime, must comply with Delta Time’s font standard.
Font files
Format
Stipple Effect font files must have the following dimensions:
- Width: multiple of 319px
 - Height: multiple of 303px
 
Parsed pixel colors
- Red (
#ff0000) - parsed as part of the glyph
 associated with its bounding box - Green (
#00ff00) - parsed as left- or right pixel boundary of the glyph associated with its bounding box at that particular pixel height

Boundary enforcement
Explicitly defining boundaries using the color green can a few applications, including:
- defining monospaced
 fonts 

- enforcing spacing for sequences of characters that would otherwise overlap or interlock
 

Character sets
Fonts support following character sets:

- Latin Extended
 

Future updates will aim to extend the characters supported by fonts, which will eventually mean additional character sets.
The ASCII character set is must be provided by user-defined fonts. Additional character sets are optional.
Uploading fonts
Fonts can be uploaded while using the text tool with Shift + T, or by clicking on 
 in the tool options bar.
