LargePictureMaskColor property for PowerScript controls


ListView controls


The mask color is the color in the picture that is transparent
when the picture is displayed.

Select the color to mask newly added user-defined bitmaps.
In scripts, you can change the mask color before adding each picture.
Each image uses the mask color that was in effect when it was added.


In a painter

proc.png To specify a picture mask color:

  1. Select a color from the Picture Mask Color
    drop-down list on the Large Picture tab page of the control’s
    Properties view.

To add your own colors to the color drop-down list, select
Design>Custom Colors before displaying the Properties view.

In scripts

The LargePictureMaskColor property takes a long (-2 to 16,777,215)
that specifies the numerical value of the background color. This
property is used when each bitmap is added and, therefore, can be
changed between AddLargePicture calls.

The LargePictureMaskColor 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.

The following example sets yellow as the mask color for user-defined
bitmaps in a ListView:
