RoboFont makes it possible to perform common boolean path operations (difference, union, intersection and exclusive or) with glyph objects directly, using special characters as operators.

Example

Here are the four boolean path operations in action. Note that, for the difference operation, the order of the operands matters.

f = CurrentFont()
g1 = f['A']
g2 = f['B']

# difference 1
r = g1 % g2
g = f.newGlyph('difference_1')
g.appendGlyph(r)

# difference 2
r = g2 % g1
g = f.newGlyph('difference_2')
g.appendGlyph(r)

# union
r = g2 | g1
g = f.newGlyph('union')
g.appendGlyph(r)

# intersection
r = g2 & g1
g = f.newGlyph('intersection')
g.appendGlyph(r)

# xor
r = g2 ^ g1
g = f.newGlyph('xor')
g.appendGlyph(r)
