recordingPen¶
Pen recording operations that can be accessed or replayed.
-
fontTools.pens.recordingPen.
replayRecording
(recording, pen)[source]¶ Replay a recording, as produced by RecordingPen or DecomposingRecordingPen, to a pen.
Note that recording does not have to be produced by those pens. It can be any iterable of tuples of method name and tuple-of-arguments. Likewise, pen can be any objects receiving those method calls.

class
fontTools.pens.recordingPen.
RecordingPen
[source]¶ Pen recording operations that can be accessed or replayed.
The recording can be accessed as pen.value; or replayed using pen.replay(otherPen).
from fontTools.ttLib import TTFont from fontTools.pens.recordingPen import RecordingPen
glyph_name = ‘dollar’ font_path = ‘MyFont.otf’
font = TTFont(font_path) glyphset = font.getGlyphSet() glyph = glyphset[glyph_name]
pen = RecordingPen() glyph.draw(pen) print(pen.value)
-
class
fontTools.pens.recordingPen.
DecomposingRecordingPen
(glyphSet)[source]¶ Same as RecordingPen, except that it doesn’t keep components as references, but draws them decomposed as regular contours.
The constructor takes a single ‘glyphSet’ positional argument, a dictionary of glyph objects (i.e. with a ‘draw’ method) keyed by thir name.
>>> class SimpleGlyph(object): ... def draw(self, pen): ... pen.moveTo((0, 0)) ... pen.curveTo((1, 1), (2, 2), (3, 3)) ... pen.closePath() >>> class CompositeGlyph(object): ... def draw(self, pen): ... pen.addComponent('a', (1, 0, 0, 1, -1, 1)) >>> glyphSet = {'a': SimpleGlyph(), 'b': CompositeGlyph()} >>> for name, glyph in sorted(glyphSet.items()): ... pen = DecomposingRecordingPen(glyphSet) ... glyph.draw(pen) ... print("{}: {}".format(name, pen.value)) a: [('moveTo', ((0, 0),)), ('curveTo', ((1, 1), (2, 2), (3, 3))), ('closePath', ())] b: [('moveTo', ((-1, 1),)), ('curveTo', ((0, 2), (1, 3), (2, 4))), ('closePath', ())]
