TRANSPARENT attribute

Makes the background color of the image transparent. The background color is determined by the color of the pixel in the lower-left corner of the image.
Data type: LOGICAL
Access: Readable/Writeable
Applies to: IMAGE widget
The TRANSPARENT attribute overrides the CONVERT-3D-COLORS attribute; if both TRANSPARENT and CONVERT-3D-COLORS are set to TRUE, CONVERT-3D-COLORS is ignored.
This attribute has no effect if an icon is displayed on the image widget.
