Detailed Description

This class represents the MILX Qt Image Display object using VTK.

Author: Shekhar S. Chandra, 2013

The class displays image values using OpenGL via the VTK library. itk::Image or vtkImageData can be passed to this class and a number of processes generated from the data.

The rendering is encapsulated within a QVTK widget.

Controls:

Left Mouse (hold): adjust the colour level.
Wheel: zoom the camera.
Middle Mouse (hold): translate image.
Right Mouse: context menu and zoom toggle.
Keypress f: fly to the picked point.
Keypress Shift+r: reset the camera view along the current view direction. Centers the actors and moves the camera so that all actors are visible.
Keypress r: reset the colour level to defaults.

Usage Example:

milxQtImage *image = new milxQtImage;
image->setName(imgName);
    image->setData(newImg);
    image->generateImage();
    image->show();
