# CVPixelBufferCreate使用的坑

```
CVReturn status = CVPixelBufferCreate(kCFAllocatorDefault, imageSize.width,
                                      imageSize.height, kCVPixelFormatType_32ARGB, (__bridge CFDictionaryRef) options,
                                      &pxbuffer);
```

这个方法在使用的时候 一定要保存图片数据的宽度是16的整倍数,否则显示出的图片会变形
