InvertImage Method (MedicalViewerCell)

Summary

Inverts all the images in the cell.

Syntax

C++

public void InvertImage()

Public Sub InvertImage()

public: 
void InvertImage();

Remarks

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