Explanation
The IKRasterToVector function converts a raster image to
a vector image. Supports black and white (1 bit) images.
If during processing, the time exceeds the TimeOutSeconds, the
process will be concelled.
When Caption, Message, and ButtonName are blank, the progress
dialog will not be displayed. When the progress dialog is
displayed, the percentage that the processing has completed will be
shown in the dialog.
