BooleanOperations

Boolean operations on paths which uses a super fast polygon clipper library by Angus Johnson.

You can download the latest version from PyPI:

https://pypi.org/project/booleanOperations.

Install

Pip is the recommended tool to install booleanOperations.

To install the latest version:

pip install booleanOperations

BooleanOperations depends on the following packages:

• pyclipper: Cython wrapper for the C++ Clipper library
• fonttools

All dependencies are available on PyPI, so they will be resolved automatically upon installing booleanOperations.

BooleanOperationManager

Containing a BooleanOperationManager handling all boolean operations on paths. Paths must be similar to defcon, robofab contours. A manager draws the result in a pointPen.

from booleanOperations import BooleanOperationManager

manager = BooleanOperationManager()

BooleanOperationManager()

Create a BooleanOperationManager.

manager.union(contours, pointPen)

Performs a union on all contours and draw it in the pointPen. (this is a what a remove overlaps does)

manager.difference(contours, clipContours, pointPen)

Knock out the clipContours from the contours and draw it in the pointPen.

manager.intersection(contours, clipContours, pointPen)

Draw only the overlaps from the contours with the clipContoursand draw it in the pointPen.

manager.xor(contours, clipContours, pointPen)

Draw only the parts that not overlaps from the contours with the clipContoursand draw it in the pointPen.

manager.getIntersections(contours)

Returning all intersection for the given contours

BooleanGlyph

A glyph like object with boolean powers.

from booleanOperations.booleanGlyph import BooleanGlyph

booleanGlyph = BooleanGlyph(sourceGlyph)

BooleanGlyph(sourceGlyph)

Create a BooleanGlyph object from sourceGlyph. This is a very shallow glyph object with basic support.

booleanGlyph.union(other)

Perform a union with the other. Other must be a glyph or BooleanGlyph object.

result = BooleanGlyph(glyph).union(BooleanGlyph(glyph2))
result = BooleanGlyph(glyph) | BooleanGlyph(glyph2)

booleanGlyph.difference(other)

Perform a difference with the other. Other must be a glyph or BooleanGlyph object.

result = BooleanGlyph(glyph).difference(BooleanGlyph(glyph2))
result = BooleanGlyph(glyph) % BooleanGlyph(glyph2)

booleanGlyph.intersection(other)

Perform a intersection with the other. Other must be a glyph or BooleanGlyph object.

result = BooleanGlyph(glyph).intersection(BooleanGlyph(glyph2))
result = BooleanGlyph(glyph) & BooleanGlyph(glyph2)

booleanGlyph.xor(other)

Perform a xor with the other. Other must be a glyph or BooleanGlyph object.

result = BooleanGlyph(glyph).xor(BooleanGlyph(glyph2))
result = BooleanGlyph(glyph) ^ BooleanGlyph(glyph2)

booleanGlyph.removeOverlap()

Perform a union on it self. This will remove all overlapping contours and self intersecting contours.

result = BooleanGlyph(glyph).removeOverlap()
