From Point to Line to Letter

Font Representation

Fonts can be represented as

Raster Graphics or Pixel Graphics
Vector-Graphics
- Outlines or Midlines
- Curves or Line Segments
- Circular Arcs or Bezier-Curves

What are the pros and cons of the various representations?

Parametric Letters

Letter J example

This is an example of a parametric `J` for Processing 3.0.
It uses midlines rather than the outlines to represent the letter
`tweak` the sketch to play with the parameters.

Source Code

Here is the source for our little "J" example.
