Cmg is inspired by Filterpedia.

Usage

Basics

Example for GaussianBlur filter

Default filter

let filteredImage = GaussianBlur().processing(image)

Edit for filter parameter

var filter = GaussianBlur()
filter.radius = 15.0
let filteredImage = filter.processing(image)

Edit for filter parameter (using closure)

let filteredImage = GaussianBlur()
      .configuration(){ filter in filter.inputRadius.setValue(15) }
      .processing(image)

Filter Group

let filterGroup = FilterGroup(name: "FilterGroupExample", [
    BoxBlur().configuration({ filter in filter.inputRadius.setValue(15) }),
    Vignette(),
    PhotoEffectMono(),
    ])

let filteredImage = filterGroup.processing(image)

Filter Chaining

let filteredImage = image.cmg_chain([
    ComicEffect(),
    GaussianBlur().configuration({ filter in
        filter.inputRadius.setValue(15)
    }),
    PerspectiveTile(imageSize: image.size).configuration({ filter in
        filter.inputTopLeft.setVector(Vector2(x: 118.0, y: 490.0).ciVector)
    }),
    ])

Demo

Please see Demo project. (Support Filter ShowCase) Please try on iOS Devices. Simulator is very slow...
