InvertImage Method

Summary
Inverts the image in the specific sub-cell.
Syntax
C#
C++/CLI
public void InvertImage( 
   int subCellIndex 
) 
            public: 
void InvertImage(  
   int subCellIndex 
)  

Parameters

subCellIndex
The zero-based index of the sub-cell that has the image being inverted.

Remarks
  • It is strongly recommended to use this function to invert the image. Using any external command for inversion could result in loss of the inversion if the user manipulates the window level values using the window level action.
