InvertImage(Int32) Method

Summary

Inverts the image in the specific sub-cell.

Syntax

C++

public void InvertImage(  
   int subCellIndex 
)

Public Overloads Sub InvertImage( _ 
   ByVal subCellIndex As Integer _ 
)

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.
