//----------------------------------------------
// Inputs:

// QString filename - location of original image on disk

// Outputs:
// --------
// QImage* returned - constructed image

// Description:
// ------------
// This method constructs an inverted version of
// the image using Qt's invertPixels method. If we were
// to do this on our own special care to correctly handle the color
// depth would be necessary.
