quentinfasquel/cafilterbuiltins

`CAFilterBuiltins` is a Swift package that provides a convenient wrapper around Apple’s private `CAFilter` class through `_CAFilter`.

✨ Features

Swift wrapper _CAFilter around CAFilter
API style inspired by CoreImage.CIFilterBuiltins
Cleaner, more expressive syntax for working with Core Animation filters
Planned support for an exhaustive list of CAFilters

📦 Installation

Swift Package Manager

Add the following to your Package.swift:

dependencies: [
    .package(url: "https://github.com/<your-username>/CAFilterBuiltins.git", from: "0.1.0")
]

🚀 Usage

import CAFilterBuiltins

// Example: Create a blur filter
let blur = _CAFilter.gaussianBlur()
blur.inputRadius = 10

// Given a `layer: CALayer`
layer.setFilters([blur])

🔮 Roadmap

[x] Transparent wrapper around CAFilter (_CAFilter)
[x] Expose protocols for all known filters
[ ] Add typed properties to protocols (currently supported: gaussianBlur, variableBlur)
[ ] SwiftUI integration examples
