Stained Glass

The Stained Glass effect creates an image that appears to be a piece of stained glass, lit from behind. The strength of the light shining through the glass can be varied from a soft, even glow to a focused brilliance.

Opacity	Sets the opacity of the effect over the input image. A value of 0 makes the effect completely transparent, while a value of 100 makes it completely opaque.

Light Intensity	Set higher values to increase the intensity of the light source, or set lower values to decrease the intensity.
Background Color	Sets the color for background regions of the effect. Set a color using the sliders.
