Glass
 
 
 

The Glass effect distorts an image. The final result appears to be viewed through a refracting glass surface.

Name

Specifies the operator's name.

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.

Use Alpha As Mask

Uses the input image's alpha channel as a mask for applying the effect. The effect is fully applied to areas of the image where the alpha channel is white, and not at all to areas where it is black.

Run Effect On

Enable the RGB and/or Alpha options to specify whether the effect is applied to the RGB channels, the Alpha channel, or both.

Distortion

Set higher values to increase the amount of distortion caused by the selected glass surface, or set lower values to decrease the amount of distortion.

Smoothness

Set higher values to make the resulting image smoother, or set lower values to make it sharper.
