Turn font glyphs into numpy arrays

Project description

Tensorfont is a library to help those performing numerical analysis of font data, particular with reference to letterfitting and spacing.

Here is an example session:

>>> from tensorfont import Font
>>> f = Font("../atospace/kern-dump/normal/MrsEavesOT-Bold.otf")

>>> f.m_width
828.0
>>> f.baseline_ratio
0.28835063437139563

>>> f.pair_distance("A","V")
-149
>>> f.pair_kerning("A","V")
-73

>>> f.glyph("G").lsb
71

>>> m = f.glyph("G").as_matrix()
    .with_sidebearings()
    .crop_descender()
    .scale_to_height(50)
>>> m.left_contour()
array([25, 22, 20, 18, 16, 15, 14, 13, 12, 11, 10, 10,  9,  9,  8,  8,  7,
        7,  7,  6,  6,  6,  6,  6,  6,  6,  6,  6,  6,  6,  6,  6,  7,  7,
        7,  7,  8,  8,  9, 10, 10, 11, 12, 13, 13, 15, 16, 17, 19, 21])
>>> plt.imgshow(m) ; plt.show()
# The letter "G" is shown
