Document

Tries to make a new bitmap based on the dimensions of this bitmap, setting the new bitmap's config to the one specified, and then copying this bitmap's pixels into the new bitmap.

Usage

From source file:Main.java

public static Bitmap setShadow(Bitmap bitmap, int radius) {
    BlurMaskFilter blurFilter = new BlurMaskFilter(radius, BlurMaskFilter.Blur.OUTER);
    Paint shadowPaint = new Paint();
    shadowPaint.setAlpha(50);//ww w  .  j a v a  2 s  .co  m
    shadowPaint.setColor(0xff424242);
    shadowPaint.setMaskFilter(blurFilter);
    int[] offsetXY = new int[2];
    Bitmap shadowBitmap = bitmap.extractAlpha(shadowPaint, offsetXY);
    Bitmap shadowImage32 = shadowBitmap.copy(Bitmap.Config.ARGB_8888, true);
    Canvas c = new Canvas(shadowImage32);
    c.drawBitmap(bitmap, -offsetXY[0], -offsetXY[1], null);
    return shadowImage32;
