I have made the MPR application based on the fourpaneviewer and I can manage the window level and width using the left mouse. For example when I changing the window level and width over the axial viewer by using the mouse and when I turns into negative the width(or both window level and width as negative), and clicking the reset window level and width button it turns into binary format… even the window level and width value shows as positive.
Here I attaching those images:
Normal Window level and width
After adjusting into negative values
After resetting the value
How can I resolve this issue. I’m currently using VTK 8.2.
