# FastImageSize
[  ](https://bintray.com/qstumn/maven/FastImageSize/_latestVersion)
FastImageSize是一个快速获得网络图片尺寸信息和图片类型的android libary
FastImageSize通过读取图片文件头解析图片信息不需要完全下载图片，内部建有三级缓存，可以快速轻松的实现设置占位图尺寸、图片流式布局、动态调整View尺寸等功能。
## how to use:
### 1.gradle
```groovy
compile 'q.rorbin:FastImageSize:1.0.3'
```
VERSION_CODE : [here](https://github.com/qstumn/FastImageSize/releases)
### 2.code
```java
int[] imageSize;
//sync
imageSize = FastImageSize.with(url).get();
//async
FastImageSize.with(url).get(new ImageSizeCallback() {
@Override
public void onSizeReady(int[] size) {
imageSize = size;
}
});
int imageWidth = imageSize[0];
int imageHeight = imageSize[1];
int imageType = imageSize[2];
```
或者你需要FastImageSize根据图片尺寸帮你设置View宽高 ：
```java
FastImageSize.with(url).into(imageView);
FastImageSize.with(url).override(500).into(imageView);
```
override方法可以根据你提供的限制值对宽高结果进行等比例缩放
FastImageSize默认使用UrlConnection获取InputStream读取图片的文件头，可以替换成你自己使用的第三方库，按以下方法调用即可
```java
FastImageSize.with(url).customProvider(yourProvider).get();
```
FastImageSize默认使用LruCache和DiskLruCache实现内存缓存和磁盘缓存，如果你不需要缓存每次都要重新读取，按以下方法调用即可
```java
FastImageSize.with(url).setUseCache(false).into(imageView);
```
### 3.permission
```xml
```
### 4.support
