## 介绍

Android图片压缩结合多种压缩方式，常用的有尺寸压缩、质量压缩以及通过JNI调用libjpeg库来进行压缩，三种方式结合使用实现指定图片内存大小，清晰度达到最优。

## 使用

* 导入lib-bither-compress

```java

	NativeUtil.compressBitmap(bitmap, savePath);

	NativeUtil.compressBitmap(bitmap, savePath, maxByte, quality);

```

* 图像建议尺寸

```Java

    public final static int QUALITY_320P = 320;//480, 320

    public final static int QUALITY_360P = 360;//640, 360

    public final static int QUALITY_480P = 480;//640, 480

    public final static int QUALITY_720P = 720;//1280, 720

    public final static int QUALITY_1080P = 1080;//1920, 1080

    public final static int QUALITY_2K = 1440;//2560, 1440

    public final static int QUALITY_4K = 2160;//3840, 2160

```

* 图像默认品质

```Java

    //见 NativeUtil 中 compressBitmap(bitmap, savePath, maxByte, quality) 方法

    int options = 80;//100不压缩品质

```

> 注意：默认将图像压缩到 1280*720 的尺寸，品质为 80 ，图像大小为 1 MB。其他配置可在 lib-bither-compress 中 NativeUtil 下自己配置。

## 对比
