GlyphMorf is an experimental way for making parametric adjustments for a font.
GlyphMorf analyses the glyph drawing and extract parameters out of it. By redrawing the glyph with different parameters you get different new glyphs / fonts.
Drawing conventions for GlyphMorf
The drawing should be so that every point on the contour can be paired with an other point in the same contour on the other side of the stem/stroke. This means that all contours must have an even number of points. The starting point marks the beginning of the inner or outer part of the contour, depends a bit on the design.
Recipes are the way to store different transformations in the font and glyphs. The font known the names of recipes and the default values of the parameters. A glyph can have a own set of parameters for a recipe but this is optional.
