Swift Library For Performing Many Common Image Processing Tasks


Some time ago I mentioned the Swift based Toucan for image editing tasks such as resizing, cropping, and adding borders to images.

Here’s an open source Swift library called SwiftImageProcessing from Sungcheol Kim for easily performing an extensive number of common image processing tasks.

These tasks include:

Convert UIImage to an RGBA image for easy pixel access
Image adding, subtraction, multiplication and division
Brightness adjustment
Contrast adjustment
Grabbing and images color space (red, green, blue)

and more.

Here’s an image from the readme showing an image with contrast adjusted:


You can find SwiftImageProcessing on Github here.
