booleanOperations 0.6.0

Boolean operations on paths.

[](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)

As of September 2016, only pyclipper is available on PyPI and therefore installed automatically with booleanOperations. The fonttools version 3.0 available from PyPI is too old, whereas ufoLib simply is not on PyPI yet, hence you need to install them separately.

You can use pip to install them from the respective git repositories:

` pip install git+https://github.com/behdad/fonttools.git pip install git+https://github.com/unified-font-object/ufoLib.git `

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()

---

#### booleanGlyph.name

The name of the sourceGlyph.

#### booleanGlyph.unicodes

#### booleanGlyph.width

The width of the sourceGlyph.

#### booleanGlyph.lib

The lib of the sourceGlyph.

#### booleanGlyph.note

The note of the sourceGlyph.

#### booleanGlyph.contours

List the contours of the glyph.

#### booleanGlyph.components

List the components of the glyph.

#### booleanGlyph.anchors

List the anchors of the glyph.
