FourPatchFrameBuilder

@objc(IMGLYFourPatchFrameBuilder) open class FourPatchFrameBuilder: NSObject, FrameBuilder

Builds a four patch frame, by spiltting the frame asset in four pieces and paint it onto the UIImage. The pieces are cropped at the insides to match the image ratio. The input image must have a ratio of 1:1. The algorithm to place and crop, each piece, leaves the sides of the asset uncropped that touch the longer side of the image. The other sides get cropped, starting from the middle, so that the corners of the asset, is touching the corners of the composet image. One could say the asset that is used as base, for the composition is pushed together along the x or y axis, depending on the ratio of, the given size.
