ClippingBezier calculates intersection points, paths, and shapes between two UIBezierPaths

ClippingBezier in Loose Leaf

The ClippingBezier.framework powers the scissors tool in Loose Leaf, and it allows for drawing to be clipped to any imported image scraps.

Available as a Swift Package!

Install ClippingBezier in your project through Swift Package Manager as of v1.2.0!

Building the framework

This library will generate a proper static framework bundle that can be used in any iOS7+ project.

Including in your project

  1. Link against the built framework and the included PerformanceBezier framework
  2. Add "-ObjC++ -lstdc++" to the Other Linker Flags in the project's Settings
  3. #import <PerformanceBezier/PerformanceBezier.h>
  4. #import <ClippingBezier/ClippingBezier.h>

Dependencies

This library depends on the UIBezierPath performance improvements in the PerformanceBezier library.

Example

UIBezierPath* aClosedPath = /* some path */;
UIBezierPath* scissorPath = /* some other path */;

NSArray* subshapes = [aClosedPath uniqueShapesCreatedFromSlicingWithUnclosedPath:scissorPath];
for(DKUIBezierPathShape* shape in subshapes){
    UIBezierPath* aClosedPathSlice = shape.fullPath;
}

Sample Application

The Xcode workspace includes a ClippingExampleApp project that shows a fully functional integration of the ClippingBezier framework. You can refer to this example for any questions about how to integrate into your app.
