Mirror effect

Mirror effect makes the viewer to see the image as it would look like through a mirror. You can do it by turning 2 checkboxes on and off, making the pictures being swapped by X and Y axis. You also have the option to check both checkboxes at the same time creating an image mirrored horizontally and verticaly. By using OZEKI Camera SDK you can create an application which is capable mirroring a video image in real time.

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


MirrorX: With this option we can manipulate the image by swapping it horizontally.

MirrorY: By using this method we can manipulate the image by swapping it vertically.
