Snow Image Effect for android



Please use below class and pass the bitmap to this function and get return bitmap with Snow effect.




public class NewSnowFilter {

      public static final int COLOR_MIN = 0x00;
      public static final int COLOR_MAX = 0xFF;

      public static Bitmap applySnowEffect(Bitmap bitmap) {
            // get image size
            int width = bitmap.getWidth();
            int height = bitmap.getHeight();
            int[] pixels = new int[width * height];
            // get pixel array from source
            bitmap.getPixels(pixels, 0, width, 0, 0, width, height);
            // random object
            Random random = new Random();

            int R, G, B, index = 0, thresHold = 50;
            // iteration through pixels
            for (int y = 0; y < height; ++y) {
                  for (int x = 0; x < width; ++x) {
                        // get current index in 2D-matrix
                        index = y * width + x;
                        // get color
                        R = Color.red(pixels[index]);
                        G = Color.green(pixels[index]);
                        B = Color.blue(pixels[index]);
                        // generate threshold
                        thresHold = random.nextInt(COLOR_MAX);
                        if (R > thresHold && G > thresHold && B > thresHold) {
                              pixels[index] = Color.rgb(COLOR_MAX, COLOR_MAX, COLOR_MAX);
                        }
                  }
            }
            // output bitmap
            Bitmap bmOut = Bitmap
                        .createBitmap(width, height, Bitmap.Config.RGB_565);
            bmOut.setPixels(pixels, 0, width, 0, 0, width, height);
            return bmOut;
      }
