## The `maskcolor' property

Not implemented under MacOS

Integer scalar or 3-element vector

Valid for: Tree

When you specify an image in an ImageList object using the `imagenames` property or `Addimages` method, you can provide a mask which indicates that certain portions of the image should be transparent. The `maskcolor` property provides an alternative way of achieving a similar effect. As new images are added, and provided no explicit mask is specified for a given image, any pixel in the bitmap which matches the color specified in `maskcolor` will be set to be transparent.

You can specify `maskcolor` as a three-element vector of Red, Green and Blue color values, each in the range 0 to 255, or as a single integer encoding the color as 256 ƒ Blue Green Red.
