Currently it support [\nAlpha Compositing](https://developer.apple.com/library/content/documentation/Performance/Conceptual/vImage/AlphaCompositingOperations/AlphaCompositingOperations.html#//apple_ref/doc/uid/TP30001001-CH208-SW1) and [Geometry](https://developer.apple.com/library/content/documentation/Performance/Conceptual/vImage/GeometricOperations/GeometricOperations.html) including thesse:\n\n+ Alpha Compositing for image and color\n+ Alpha Compositing for image and image\n+ Image Scale\n+ Image Cropping\n+ Image Flipping\n+ Image Rotation\n+ Image Shearing\n+ Image Affine Transform\n\nAll these methods use vImage API but not Core Graphics to do image processing, which is more performant.\n\nThis project is more like a demo to show how vImage can be used to benefit some hign-efficient image processing on Apple platform. You can also use these methods in your own image framework.\n\n## Example\n\nTo run the example project, clone the repo, and run `pod install` from the Example directory first.\n\nThere are 8 demo cases to show the feature about vImage. Currently it do not have some powerful feature like [Convolution](https://en.wikipedia.org/wiki/Kernel_\\(image_processing\\)) or [vDSP](https://developer.apple.com/library/content/documentation/Performance/Conceptual/vDSP_Programming_Guide/Introduction/Introduction.html), because it need more knowledge about [DSP](https://en.wikipedia.org/wiki/Digital_signal_processing). Through Accelerate and vImage support these feature, [GPUImage](https://github.com/BradLarson/GPUImage) may be a better place to get start.\n\n## Requirements\n\n+ iOS 7+\n+ macOS 10.8+\n+ tvOS 9+\n+ watchOS 2+\n\n## Installation\n\nvImageProcessor is available through [CocoaPods](http://cocoapods.org). To install\nit, simply add the following line to your Podfile:\n\n```ruby\npod 'vImageProcessor'\n```\n\n## Screenshot\n\nAlpha Compositing | Cropping | Affine Transform\n:-: | :-: | :-:\n![](https://raw.githubusercontent.com/dreampiggy/vImageProcessor/master/Example/Screenshot/Screenshot1.png) | ![](https://raw.githubusercontent.com/dreampiggy/vImageProcessor/master/Example/Screenshot/Screenshot2.png) | ![](https://raw.githubusercontent.com/dreampiggy/vImageProcessor/master/Example/Screenshot/Screenshot3.png)\n\n## Author\n\nDreamPiggy\n\n## License\n\nvImageProcessor is available under the MIT license.
