| ---------------------------------- | ----------------------------- |
| BlurTransformation | 模糊处理 |
| BrightnessTransformation | 亮度滤波器 |
| CropCircleTransformation | 圆形剪裁显示 |
| CropCircleWithBorderTransformation | 圆环展示 |
| CropSquareTransformation | 正方形剪裁 |
| CropTransformation | 自定义矩形剪裁 |
| GrayScaleTransformation | 灰度级滤波器 |
| InvertTransformation | 反转滤波器 |
| KuwaharaTransformation | 桑原滤波器（使用GPUIImage） |
| MaskTransformation | 遮罩 |
| PixelationTransformation | 像素化滤波器（使用GPUIImage） |
| SepiaTransformation | 乌墨色滤波器（使用GPUIImage） |
| SketchTransformation | 素描滤波器（使用GPUIImage） |
| SwirlTransformation | 扭曲滤波器（使用GPUIImage） |
| ToonTransformation | 动画滤波器（使用GPUIImage） |
| VignetterTransformation | 装饰滤波器（使用GPUIImage） |
## 下载安装GPUImage依赖
方法一：在Terminal窗口中，执行如下命令安装三方包，DevEco Studio会自动在工程的oh-package.json5中自动添加三方包依赖。
```
ohpm install @ohos/gpu_transform
```
方法二： 在工程的oh-package.json5中设置三方包依赖，配置示例如下：
```
"dependencies": {
"@ohos/gpu_transform": "^1.0.2"
}
```
