Syntax

C#
VB
C++
public void FlipLabels() 
  
Public Sub FlipLabels()  
             
            public: 
void FlipLabels();  
             

Remarks

The labels (overlay tags) are the text that are docked to the top-center, bottom-center, left-center and right-center of the cell. To set those labels, use the method SetTag.

To flip the image, use the method MedicalViewerCell.FlipImage.
