8 | 9 | ## 二、前言 10 | GPUImage 是一个开源的图像渲染的库，使用它可以轻松实现很多滤镜效果，也可以很轻松的定义和实现自己特有的滤镜效果。 11 | 12 | 地址：[https://github.com/cats-oss/android-gpuimage](https://github.com/cats-oss/android-gpuimage) 13 | 14 | ## 三、依赖工程 15 | 要想使用 GPUImage，使用 Android Studio 只需要在 build.gradle 里面添加相关的依赖即可。 16 | ``` 17 | implementation 'jp.co.cyberagent.android:gpuimage:2.0.3' 18 | ``` 19 | 20 | ## 四、GPUImage 类介绍 21 | ### 1. 目录结构 22 | 23 | |--- filter ： 这个包下面是各种滤镜效果类。 24 | |--- util ： 这个包下面是一些工具类。 25 | |--- GLTextureView ： 继承自 TextureView，和 GLSurfaceView 功能类似。 26 | |--- GPUImage ： 核心实现类，配合 GLSurfaceView/GLTextureView 和 GPUImageFilter 实现渲染。 27 | |--- GPUImageNativeLibrary ： 包含一些图片转码的 native 方法。 28 | |--- GPUImageRenderer ： 实际的渲染者。 29 | |--- GPUImageView ： 继承自 FrameLayout，封装了一个 GPUImage 和 GPUImageFilter，使用起来更方便。 30 |
