Description: This article is about a CStatic derived class that supports multiple bitmap layers. The CLayeredBitmapCtrl class allows you to add/remove/show/hide bitmap layers on a static control. Each bitmap layer can have a user defined transparent color or retrieve the transparent color from a specified location in the bitmap. This allows the background bitmap to be visible through the transparent color of another bitmap layer. Tool tips are also used so that each layer can display its own description. Each layer can also have a non-transparent region that allows the tool tip to be displayed only when the mouse is over the non-transparent portion of the layer. The first layer is not usually set to transparent because it is used as the background. All of the other layers should have the transparent flag set, otherwise the first layer will not be visible, unless the layer is smaller and rectangular.
