Color Gel

Quick Reference to Scripting Command
a=GEL(RED, GREEN, BLUE)
Items in CAPS are 0/1 switches or switches with more options than 0/1.

This operation will convert the specified area to a solid Red, Green, or Blue color palette.

You also have the option of combining the RGB components to produce cyan, yellow, or magenta color gels.

The color channels that are applied by this operation are controlled by selecting the desired components check box. If a RGB component is selected, it will then be applied to the specified area in the image. The overall effect of the operation is similar to color filter effects accomplished through transparent lighting gels or color camera filtration.

You should be aware that there is a loss of brightness just as there is with real color gels due to the fact that this is a limited-transmission process. You can compensate for this if you wish with the brightness or the force dynamic option of the Balance operation.

These three check box controls allow you to alter the coloration of the color gel that is applied to the image. Selecting one of the check boxes will cause that color component to be used as part of the color gel calculation. If more than one box is selected, then the color will be a combination of the two color components. It is not allowed to select all three color components, since this will result in an all black image.
