pictureMask

Type: Binary

Availability: Read or write at any time

The pictureMask property of the JadeMask class contains the picture that defines the mask for the control and specifies the logical area of the control.

Any pixel with the color of the activeColor property in the mask picture defines a pixel within the logical control. A pixel of any other color in the mask is considered not to be on the control and the control will not respond while the mouse is over that pixel.

The picture for the mask can be a bitmap, PNG, GIF, JPEG, or TIFF image only.

The masking ability is disabled if the value of the rotation property is non-zero or the value of the style property is Style_Mask_Color (3).

The mask picture is never shown. (See also the JadeMask class createRegionFromMask property.)

If the value of the pictureMask property is null (""), the roll over and roll under effects (controlled by the pictureRollOver and pictureRollUnder properties) occur when the mouse is over any part of the control.
