IntersectGlyphWithLine(glyph, line, canHaveComponent=False, addSideBearings=False)

Intersect a glyph with a line. Returns a list of intersections.

IntersectGlyphWithLine(myGlyph, ((100, 50), (800, 50)), canHaveComponent=True, addSideBearings=True)

union(glyph, subjectContours, clipContours, roundCoordinates=None)

Draw the union between subjectContours and clipContours into the destination glyph.

union(glyph, subjectContours, clipContours, roundCoordinates=None)

Both subjectContours and clipContours can be a list of contour objects or a glyph object.

If roundCoordinates is None, the default rounding value in the Preferences will be used.

difference(glyph, subjectContours, clipContours, roundCoordinates=None)

Draw the difference between subjectContours and clipContours into the destination glyph.

difference(glyph, subjectContours, clipContours, roundCoordinates=None)

Both subjectContours and clipContours can be a list of contour objects or a glyph object.

If roundCoordinates is None, the default rounding value in the Preferences will be used.

intersection(glyph, subjectContours, clipContours, roundCoordinates=None)

Draw the intersection between subjectContours and clipContours into the destination glyph.

intersection(glyph, subjectContours, clipContours, roundCoordinates=None)

Both subjectContours and clipContours can be a list of contour objects or a glyph object.

If roundCoordinates is None, the default rounding value in the Preferences will be used.

xor(glyph, subjectContours, clipContours, roundCoordinates=None)

Draw the exclusive or (XOR) between subjectContours and clipContours into the destination glyph.

xor(glyph, subjectContours, clipContours, roundCoordinates=None)

Both subjectContours and clipContours can be a list of contour objects or a glyph object.

If roundCoordinates is None, the default rounding value in the Preferences will be used.

def myFunc(foo, bar):
    for f in range(foo):
        for b in range(bar):
            f * b

profile(myFunc, foo=10, bar=20)

profileDecorator(func)

Decorating a method with a profiler.

ScriptRunner(text=None, path=None, stdout=None, stderr=None, namespace=None, checkSyntaxOnly=False, threaded=False)

difference

result = BooleanGlyph(glyph) - BooleanGlyph(glyph2)

intersection

result = BooleanGlyph(glyph) & BooleanGlyph(glyph2)

xor

result = BooleanGlyph(glyph) ^ BooleanGlyph(glyph2)
