  The last thing will be to provide for the case where the points are in a continuous chain, like the <o>. I'm pretty sure I know what to do, and it shouldn't be that hard, but I have some other problems with the Crouwel code to fix first (all to do with graphing and finding valid paths—this whole project is forcing me to teach myself the basics of computer science as I go). I'll post the revised and extended code here when it's done.

  not directly... you can load the image as an ImageObject and use it as a context to draw something, a pixel at a specific place. im = ImageObject("http://f.cl.ly/items/1T3x1y372J371p0v1F2Z/drawBot.jpg") with im: fill(1, 0, 1) rect(0, 0, 10, 10) image(im, (10, 10))

  @frederik @justvanrossum Here's the final code with a fully working test. The code defines a design space with 45 shapes (some of which are subsets of larger shapes). The code draws each shape, then draws each unique pair of shapes whose members don't 'touch' and don't overlap. from itertools import combinations canvasX = 750 canvasY = canvasX * 1.25 u = (canvasX/50) def c1(): c = BezierPath() c.oval(-8 * u -

  @justvanrossum thanks so much! For anyone else trying this, for some reason I was getting an error when I had from fontTools.pens.recordingPen import RecordingPen error was ImportError: No module named recordingPen Perhaps because recordingPen.py isn't in the version of fontTools packaged with RoboFont? Anyway, I just copy/pasted the whole RecordingPen code from fontTools into my script: from fontTools.pens.basePen import AbstractPen class RecordingPen(AbstractPen): """Pen recording operations that can be accessed or replayed. The recording can be accessed as pen.value; or replayed using pen.replay(otherPen). Usage example: ============== 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) """ def __init__(self): self.value = [] def moveTo(self, p0): self.value.append(('moveTo', (p0,))) def lineTo(self, p1): self.value.append(('lineTo', (p1,))) def qCurveTo(self, *points): self.value.append(('qCurveTo', points)) def curveTo(self, *points): self.value.append(('curveTo', points)) def closePath(self): self.value.append(('closePath', ())) def endPath(self): self.value.append(('endPath', ())) def addComponent(self, glyphName, transformation): self.value.append(('addComponent', (glyphName, transformation))) def replay(self, pen): replayRecording(self.value, pen) and now I can run the script that Just wrote above. Thanks again!

  for DrawBot it is easy: install it as a module and you can use DrawBot as a package and write code anywhere.
