Whether you're applying a circular crop to user avatars or just resizing a photo downloaded from a web service, processing images can be a bit of a chore. Toucan is a Swift image processing library from Gavin Bunney that makes working with images a breeze.
import Toucan and take a look at what it can do:
// userAvatar is a UIImage downloaded from the network let resizedAvatar = Toucan.Resize.resizeImage( myImage, size: CGSize(width: 100, height: 100) )
Apply a Circular Mask
let circularAvatar = Toucan.maskWithEllipse(resizedAvatar)
Apply a Rounded Rectangle Mask
let roundedAvatar = Toucan.maskWithRoundedRect(height: 5)
Image Borders & Method Chaining
Toucan provides another syntax for chaining different processing steps together. Just call
.image at the end to get a final processed
UIImage. Here we can also see how to apply a 1 point wide border to the final image.
Toucan(image: userAvatar) .resize(CGSize(width: 100, height: 100)) .maskWithEllipse( borderWidth: 1, borderColor: UIColor.lightGrayColor() ) .image
