Detailed Description

This class enables the user to choose between different zooming options.

The 3 possible values determine a global scale factor used for the end result: (i) preserve sum (locally) (ii) preserve values (like interpolation) (iii) preserve projections: using a STIR forward projector on the zoomed image will give (approximately) the same projections.
