Property Value
The filename for the background image
Explanation
The PictureFile property sets the filename for the background image displayed on the thumbnail image frame when the thumbnail has not been clicked. This property could be used to create the effect of window blinds being opened to reveal a thumbnail image when the mouse is clicked on that thumbnail image frame.
This property is enabled when the Style property is vikCustom. The black RGB(0,0,0) portions of the background image is set as a transparent color. The thumbnail image will be displayed through this portion of the background image.
Note: The PictureDown and Picture properties also set a background image on the display area of the thumbnail image. However, when setting the background image during execution, it is recommended that you use the PictureFile and PictureDownFile properties.
