Klipper is supplied via JitPack.
To add it to your Android/Gradle project complete the following steps:
- Add the JitPack to your .gradle file:
repositories {
maven { url 'https://jitpack.io' }
}- Add the Klipper to your dependencies:
compile 'com.github.alexanderpp:klipper:1.0'Clipping allows you to perform boolean operations (AND, OR, NOT & XOR) on poligons.
- AND (Intersection) - create regions where both subject and clip polygons are filled;
- OR (Union) - create regions where either subject or clip polygons (or both) are filled;
- NOT (Difference) - create regions where subject polygons are filled except where clip polygons are filled;
- XOR (Exclusive or) - create regions where either subject or clip polygons are filled but not where both are filled.

Offsetting is the process of inflating/deflating both open and closed paths using a number of different join types and end types.
