Blending

In this demo there are a few couples of pictures (press arrows to see them). Any couple has the top and the bottom picture located at the same position (using absolute position). Initially you see the top picture in the main display area. You can see also two thumbnails showing the top and the bottom pictures.

Select on of the blending modes in the select area on the left. The chosen mode is applied to the top picture. The result in the display is the composition of the top and the bottom pictures.

Try different modes on different couples. Use full-screen mode for better viewing.

Try multiple colors image and apply hue or multiply mode.
