UIImageColorRatio

A tool to calculate the color ratio of UIImage in iOS.

How to use UIImageColorRatio

Get the color ratio of UIImage.

let image = ...  // your UIImage.
let result = image.calculateColorRatio(deviation: 10) // "deviation": The deviation on pixels, It's from 0 to 255. Bigger deviation means less kind of colors.

Get the effected image.

let image = ...  // your UIImage.
let result = image.calculateColorRatio(deviation: 10)
let effectedImage = image.effectedImage(colorRatioResult: result)

How to integrate UIImageColorRatio?

UIImageColorRatio can be integrated by cocoapods.

pod 'UIImageColorRatio'

Or use Swift Package Manager. SPM is supported from 1.2.0.

Performance

You can see the duration of the calculation from calculateColorRatio API's result.

You MUST use Release build configuration to see the performance. Because swfit is very slow on Debug build configuration.
