Font InspectionΒΆ
Ziafont provides some methods for inspecting a font and its glyphs. The following classes use Jupyter representers to show the output in Jupyter cells, but the output may also be obtained using the methods of the class, such as table().
To see a table of all glyphs in a font, use ziafont.inspect.ShowGlyphs.
Here, only the first 105 glyphs are shown of the default DejaVu Sans font:
font = ziafont.Font()
ziafont.inspect.ShowGlyphs(font, nmax=105)
0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 |
15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 |
30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 |
45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 | 54 | 55 | 56 | 57 | 58 | 59 |
60 | 61 | 62 | 63 | 64 | 65 | 66 | 67 | 68 | 69 | 70 | 71 | 72 | 73 | 74 |
75 | 76 | 77 | 78 | 79 | 80 | 81 | 82 | 83 | 84 | 85 | 86 | 87 | 88 | 89 |
90 | 91 | 92 | 93 | 94 | 95 | 96 | 97 | 98 | 99 | 100 | 101 | 102 | 103 | 104 |
To see the glyph substitutions made by a font feature, use ziafont.inspect.ShowFeature.
This example shows the substitutions made by the DejaVu Sans salt (Stylistic Alternatives) feature.
ziafont.inspect.ShowFeature('salt', font)
salt
Single Substitution (1 → 1)
| Glyph In | Glyph Out | ID In | ID Out | ||
|---|---|---|---|---|---|
| → | 44 | → | 6015 | ||
| → | 45 | → | 5995 | ||
| → | 68 | → | 531 | ||
| → | 79 | → | 6005 | ||
| → | 268 | → | 5970 |
Glyph info is shown with ziafont.inspect.DescribeGlyph:
ziafont.inspect.DescribeGlyph(font.glyph('B'))
| Index | 37 |
| Unicode | 0042 |
| Character | B |
| xmin | 201 |
| xmax | 1260 |
| ymin | 0 |
| ymax | 1493 |
| Advance | 1405 |
And a detail rendering of the glyph and its control points:
ziafont.inspect.InspectGlyph(font.glyph('B'))
Finally, ziafont.inspect.DescribeFont provides metadata about the font.
ziafont.inspect.DescribeFont(font)
