Fresco按照宽高压缩图片的方法

如题，如下

public static void load(Uri uri,SimpleDraweeView draweeView,int width,int height,
                 	){
        ImageRequest request =
                ImageRequestBuilder.newBuilderWithSource(uri)
                        .setResizeOptions(new ResizeOptions(width,height))
                        //缩放,在解码前修改内存中的图片大小, 配合Downsampling可以处理所有图片,否则只能处理jpg,
                        // 开启Downsampling:在初始化时设置.setDownsampleEnabled(true)
                        .setProgressiveRenderingEnabled(true)//支持图片渐进式加载
                        .setAutoRotateEnabled(true) //如果图片是侧着,可以自动旋转
                        .build();

        PipelineDraweeController controller =
                (PipelineDraweeController) Fresco.newDraweeControllerBuilder()
                        .setImageRequest(request)
                        .setOldController(draweeView.getController())
                        .setAutoPlayAnimations(true) //自动播放gif动画
                        .build();

        draweeView.setController(controller);
    }
