Saves ART marks into DICOM dataset as overlay planes. Each ART group is saved into a separate overlay plane.
Since overlay planes do not support any types of graphic objects other than bitonal bitmaps, all ART marks from a group are converted into a bitmap before saving into an overlay.
Overlay planes do not support specifying the colors (even black or white). An overlay pixel can only be visible or invisible. All visible overlay pixels are displayed with the same color, which is specified by the application and not stored in the DICOM DataSet.
This function requires ART component to be attached to ImageGear.
