示例1: blurMax

import android.renderscript.RenderScript; //導入依賴的package包/類
public static Bitmap blurMax(Context context, Bitmap image) {
    // 計算圖片縮小後的長寬
    int width = Math.round(image.getWidth() * BITMAP_SCALE);
    int height = Math.round(image.getHeight() * BITMAP_SCALE);
    // 將縮小後的圖片做為預渲染的圖片。
    Bitmap inputBitmap = Bitmap.createScaledBitmap(image, width, height, false);
    // 創建一張渲染後的輸出圖片。
    Bitmap outputBitmap = Bitmap.createBitmap(inputBitmap);
    // 創建RenderScript內核對象
    RenderScript rs = RenderScript.create(context);
    // 創建一個模糊效果的RenderScript的工具對象
    ScriptIntrinsicBlur blurScript = ScriptIntrinsicBlur.create(rs, Element.U8_4(rs));
    // 由於RenderScript並沒有使用VM來分配內存,所以需要使用Allocation類來創建和分配內存空間。
    // 創建Allocation對象的時候其實內存是空的,需要使用copyTo()將數據填充進去。
    Allocation tmpIn = Allocation.createFromBitmap(rs, inputBitmap);
    Allocation tmpOut = Allocation.createFromBitmap(rs, outputBitmap);
    // 設置渲染的模糊程度, 25f是最大模糊度
    blurScript.setRadius(25f);
    // 設置blurScript對象的輸入內存
    blurScript.setInput(tmpIn);
    // 將輸出數據保存到輸出內存中
    blurScript.forEach(tmpOut);
    // 將數據填充到Allocation中
    tmpOut.copyTo(outputBitmap);
    return outputBitmap;
}
