介绍：

一个安卓的图片压缩库。

运行效果：

使用说明：

Gradle

dependencies {
    compile 'id.zelory:compressor:1.0.4'
}

Let's compress the image size!

压缩图片文件

compressedImageFile = Compressor.getDefault(this).compressToFile(actualImageFile);

把图片文件压缩成Bitmap

compressedImageBitmap = Compressor.getDefault(this).compressToBitmap(actualImageFile);

自定义压缩

compressedImage = new Compressor.Builder(this)
            .setMaxWidth(640)
            .setMaxHeight(480)
            .setQuality(75)
            .setCompressFormat(Bitmap.CompressFormat.WEBP)
            .setDestinationDirectoryPath(Environment.getExternalStoragePublicDirectory(
              Environment.DIRECTORY_PICTURES).getAbsolutePath())
            .build()
            .compressToFile(actualImage);

使用RxJava异步压缩

Compressor.getDefault(this)
        .compressToFileAsObservable(actualImage)
        .subscribeOn(Schedulers.io())
        .observeOn(AndroidSchedulers.mainThread())
        .subscribe(new Action1<File>() {
            @Override
            public void call(File file) {
                compressedImage = file;
            }
        }, new Action1<Throwable>() {
            @Override
            public void call(Throwable throwable) {
                showError(throwable.getMessage());
            }
        });
