Add a GPU processing feature to the framework.

Images should be scaled on rotation.

This library should support the latest version of the Swift programming language (which is 3.0).

Tasks

• Swift 3 support
• Swift 2.3 support

For some reason filters do not work anymore. They can't be applied to photos nor can they be applied for previews.

Tasks

• Update CoreImage functionality to the latest SDK updates
• Fix filtering issues

Filtering operations are being performed very slow. This is a huge problem for general app performance.

Approach

Wrappers around CIFilter hierarchy are nice. But the Processor is not well optimized which makes processing a set of images kinda problematic and time consuming. This, basically, is happening because of using a default CIContext which mainly uses the CPU. Instead we'd rather use a context using GPU for the same purpose.

Tasks

• Optimize Processor implementation
• Use GPU for processing operations (also see #1)
• Update the Demo project
• Update the Pod

// TODO:

There are some issues with image scaling. Sometimes image doesn't fill all the space, especially when being rotated. It should be intuitive and smooth.

Approach

CropView should be resized appropriately to the image provided, thus given it an image NxK, the cropView.bounds.size is exactly NxK. This behavior is not the same as in the ImagePickerKit – there we only get an image and Cropable conformable object must use the provided size as a default one for both cropView and image.

Following this way, we'll get rid of any scaling issues happening while rotating the image.

Tasks

• Extend Cropable protocol to support described behavior
• Update the Demo project
• Update the Pod
