Reflection Photo Effect for android

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

public class NewReflection {

      public static final Bitmap applyReflection(Bitmap bitmap) {

            // gap space between original and reflected

            final int reflectionGap = 4;

            // get image size

            int width = bitmap.getWidth();

            int height = bitmap.getHeight();

            // this will not scale but will flip on the Y axis

            Matrix matrix = new Matrix();

            matrix.preScale(1, -1);

            // create a Bitmap with the flip matrix applied to it.

            // we only want the bottom half of the image

            Bitmap reflectionImage = Bitmap.createBitmap(bitmap, 0, height / 2,

                        width, height / 2, matrix, false);

            // create a new bitmap with same width but taller to fit reflection

            Bitmap bitmapWithReflection = Bitmap.createBitmap(width,

                        (height + height / 2), Config.ARGB_8888);

            // create a new Canvas with the bitmap that's big enough for

            // the image plus gap plus reflection

            Canvas canvas = new Canvas(bitmapWithReflection);

            // draw in the original image

            canvas.drawBitmap(bitmap, 0, 0, null);

            // draw in the gap

            Paint defaultPaint = new Paint();

            canvas.drawRect(0, height, width, height + reflectionGap, defaultPaint);

            // draw in the reflection

            canvas.drawBitmap(reflectionImage, 0, height + reflectionGap, null);

            // create a shader that is a linear gradient that covers the reflection

            Paint paint = new Paint();

            LinearGradient shader = new LinearGradient(0, bitmap.getHeight(), 0,

                        bitmapWithReflection.getHeight() + reflectionGap, 0x70ffffff,

                        0x00ffffff, TileMode.CLAMP);

            // set the paint to use this shader (linear gradient)

            paint.setShader(shader);

            // set the Transfer mode to be porter duff and destination in

            paint.setXfermode(new PorterDuffXfermode(Mode.DST_IN));

            // draw a rectangle using the paint with our linear gradient

            canvas.drawRect(0, height, width, bitmapWithReflection.getHeight()

                        + reflectionGap, paint);

            return bitmapWithReflection;

      }
