Chroma key is a visual effects technique used to replace backgrounds in images. Entré has chroma key capabilities which are used for processing personnel identification images.

Go to Configuration > System Configuration > Image Processing.

Select the appropriate chroma-key checkboxes and complete the related fields. If using chroma-key for signature images, select a Signature Background Color that corresponds to the screen color being used.

Note: Color fields use the hexadecimal color system. For example, white (R 255, G 255, Bb 255) is represented as #ffffff.
