## gpu_transform
该module通过获取图片的buffer数据，使用openGL、着色器（Shader），操作GPU，达到图片滤波器的效果。
本项目基于开源库 [android-gpuimage](https://github.com/cats-oss/android-gpuimage) 进行OpenHarmony的自研版本：
## 下载安装
```
npm install @ohos/gpu_transform --save
```
## 例子说明
```
//获取像素点数据
let bufferData = new ArrayBuffer(bitmap.getPixelBytesNumber());
await bitmap.readPixelsToBuffer(bufferData);
// 使用GPUImageVignetterFilter过滤器
let filter = new GPUImageVignetterFilter();
filter.setImageData(bufferData, targetWidth, targetHeight);
filter.setVignetteCenter(this.centerPoint);
filter.setVignetteColor(this.vignetteColor);
filter.setVignetteStart(this.vignetteSpace[0]);
filter.setVignetteEnd(this.vignetteSpace[1]);
//获取经过gpu处理的像素点数据
let buf = await filter.getPixelMapBuf(0, 0, targetWidth, targetHeight)
//像素点数据写入
bitmap.writeBufferToPixels(buf);
```
## 滤波器类型说明
| 滤波器类型 | 描述 |
| ---------------------------- | ---------------------------|
| GPUImageBlurFilter | 模糊滤波器 |
| GPUImageBrightnessFilter | 亮度滤波器 |
| GPUImageColorInvertFilter | 颜色反转滤波器 |
| GPUImageContrastFilter | 对比度滤波器 |
| GPUImageGrayscaleFilter | 灰色滤波器 |
| GPUImageKuwaharaFilter | 桑原滤波器 |
| GPUImagePixelationFilter | 马赛克滤波器 |
| GPUImageSepiaToneFilter | 乌墨色滤波器 |
| GPUImageSketchFilter | 素描滤波器 |
| GPUImageSwirlFilter | 扭曲滤波器 |
| GPUImageToonFilter | 动画滤波器 |
| GPUImageVignetterFilter | 装饰滤波器 |
