ClippingBezier

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;
}

Screenshots

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.
