In scripts
The PictureMaskColor property takes a long value (-2 to 16,777,215)
that specifies the numerical value of the mask color. The PictureMaskColor
value is a combination of values for the red, green, and blue components
of the color. If you do not know the long value for a particular
color, choose Design>Custom Colors to determine the red,
green, and blue values and then call the RGB function
to specify the color in a script. In scripts, this property is used
when each picture is added and, therefore, can be changed between AddPicture calls.
The following example sets yellow as the mask color for pictures
in a DropDownPictureListBox:
