TTF字体表

Matplotlib支持FreeType字体。下面是一个使用‘table’命令构建字体表的小示例，该表按字符代码显示字形。

用法python font_table_ttf.py somefile.ttf

  1. import sys
  2. import os
  4. import matplotlib
  5. from matplotlib.ft2font import FT2Font
  6. from matplotlib.font_manager import FontProperties
  7. import matplotlib.pyplot as plt
  9. # the font table grid
  11. labelc = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9',
  12.           'A', 'B', 'C', 'D', 'E', 'F']
  13. labelr = ['00', '10', '20', '30', '40', '50', '60', '70', '80', '90',
  14.           'A0', 'B0', 'C0', 'D0', 'E0', 'F0']
  16. if len(sys.argv) > 1:
  17.     fontname = sys.argv[1]
  18. else:
  19.     fontname = os.path.join(matplotlib.get_data_path(),
  20.                             'fonts', 'ttf', 'DejaVuSans.ttf')
  22. font = FT2Font(fontname)
  23. codes = sorted(font.get_charmap().items())
  25. # a 16,16 array of character strings
  26. chars = [['' for c in range(16)] for r in range(16)]
  27. colors = [[(0.95, 0.95, 0.95) for c in range(16)] for r in range(16)]
  29. plt.figure(figsize=(8, 4), dpi=120)
  30. for ccode, glyphind in codes:
  31.     if ccode >= 256:
  32.         continue
  33.     r, c = divmod(ccode, 16)
  34.     s = chr(ccode)
  35.     chars[r][c] = s
  37. lightgrn = (0.5, 0.8, 0.5)
  38. plt.title(fontname)
  39. tab = plt.table(cellText=chars,
  40.                 rowLabels=labelr,
  41.                 colLabels=labelc,
  42.                 rowColours=[lightgrn] * 16,
  43.                 colColours=[lightgrn] * 16,
  44.                 cellColours=colors,
  45.                 cellLoc='center',
  46.                 loc='upper left')
  48. for key, cell in tab.get_celld().items():
  49.     row, col = key
  50.     if row > 0 and col > 0:
  51.         cell.set_text_props(fontproperties=FontProperties(fname=fontname))
  52. plt.axis('off')
  53. plt.show()
