Syntax short SetRgnColor (OLE_COLOR crMatch, short iCombineMode);

Overview:  Refer to Creating and Using a Bitmap Region.

Remarks

Adds a region that consists of all pixels of a specified color.

You specify the color using a COLORREF value, which is a Windows-defined data type. You can also specify a palette index as explained in Using Palette Indexes As Color Values.

With this method, you can either replace the current region or create a complex region by setting a flag that determines how the added region interacts with the existing region. For possible values, specified in the iCombineMode parameter, refer to Flags for Setting a Region.

You can use this method to simulate the use of a transparent color as follows:
