Operation Example

In the above example, scanline width was exaggerated for example purposes. Scanline adds alernating black lines to the image, allowing you to add a TV scanline effect to animations or stills.

Warning:

Careful!!!
When resizing an image, be sure that scanline is not applied to the image until it is scaled the the final output size. If scanline is applied to an image and then that image is resized, irregular samplings will produce erratic samplings of the scanlines, leaving some sections without scanlines and some sections totally black.
