LEAD Technologies, Inc

ReverseLabels Method

Example 





Reverses the label tags of an image in the cell with the specified subCellIndex.
Syntax
public void ReverseLabels()
'Declaration
 
Public Sub ReverseLabels() 
'Usage
 
Dim instance As MedicalViewerBaseCell
 
instance.ReverseLabels()
public void ReverseLabels()
 function Leadtools.MedicalViewer.MedicalViewerBaseCell.ReverseLabels()
public:
void ReverseLabels(); 
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(Int32,MedicalViewerTagAlignment,MedicalViewerTagType).

To reverse the image, use the method MedicalViewerCell.ReverseImage.
