# YYImage  显示指定区域的图片

YYImage 显示区域与图片大小不一致时,默认显示的是居中部分 如果想指定显示区域 需要重写YYImage

以下代码为显示从1/8位置开始的图片

```
#import "PLImage.h"

@implementation PLImage

- (CGRect)animatedImageContentsRectAtIndex:(NSUInteger)index
{
return CGRectMake(0, self.size.height *  1./8., self.size.width, self.size.height);;

}

@end
```
