booleanOperations 0.6.1

Boolean operations on paths.

[](https://travis-ci.org/typemytype/booleanOperations) [](https://pypi.org/project/booleanOperations/) 

BooleanOperations

Boolean operations on paths based on a super fast [polygon clipper library by Angus Johnson](http://www.angusj.com/delphi/clipper.php).

You can download the latest version from PyPI:

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

Install

[Pip](https://pip.pypa.io/en/stable/) is the recommended tool to install booleanOperations.

To install the latest version:

` pip install booleanOperations `

BooleanOperations depends on the following packages: - [pyclipper](https://pypi.org/project/pyclipper/): Cython wrapper for the C++ Clipper library - [fonttools](github.com/behdad/fonttools) - [ufoLib](https://github.com/unified-font-object/ufoLib)

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 clipContours`and draw it in the `pointPen.

#### manager.xor(contours, clipContours, pointPen)

Draw only the parts that not overlaps from the contours with the clipContours`and 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()
