Water wave

Using water wave you can create water-like effect on images. By moving the trackbars, you can adjust the measure of horizontal waves count and amplitude and also the measure of vertical ones.

Important: you should study this article in order to find out how to setup your Windows Forms Application correctly.

Properties

HorizontalWavesCount: With this option you can set the number of horizontal distortions.

VerticalWavesCount: With this option you can set the number of vertical distortions.

VerticalWavesAmplitude: With this option you can set the size of a vertical distortion.

HorizontalWavesAmplitude: With this option you can set the size of a horizontal distortion.
