# UIImageColorRatio
A tool to calculate the color ratio of UIImage in iOS.
# How to use UIImageColorRatio
Get the color ratio of UIImage.
```swift
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](https://cocoapods.org/).
```
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.
