示例1: blurMax

import android.renderscript.Allocation; //导入依赖的package包/类
public static Bitmap blurMax(Context context, Bitmap image) {
    // 计算图片缩小后的长宽
    int width = Math.round(image.getWidth() * BITMAP_SCALE);
    int height = Math.round(image.getHeight() * BITMAP_SCALE);
    // 将缩小后的图片做为预渲染的图片。
    Bitmap inputBitmap = Bitmap.createScaledBitmap(image, width, height, false);
    // 创建一张渲染后的输出图片。
    Bitmap outputBitmap = Bitmap.createBitmap(inputBitmap);
    // 创建RenderScript内核对象
    RenderScript rs = RenderScript.create(context);
    // 创建一个模糊效果的RenderScript的工具对象
    ScriptIntrinsicBlur blurScript = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));
    // 由于RenderScript并没有使用VM来分配内存,所以需要使用Allocation类来创建和分配内存空间。
    // 创建Allocation对象的时候其实内存是空的,需要使用copyTo()将数据填充进去。
    Allocation tmpIn = Allocation.createFromBitmap(rs, inputBitmap);
    Allocation tmpOut = Allocation.createFromBitmap(rs, outputBitmap);
    // 设置渲染的模糊程度, 25f是最大模糊度
    blurScript.setRadius(25f);
    // 设置blurScript对象的输入内存
    blurScript.setInput(tmpIn);
    // 将输出数据保存到输出内存中
    blurScript.forEach(tmpOut);
    // 将数据填充到Allocation中
    tmpOut.copyTo(outputBitmap);
    return outputBitmap;
