Use Nearest Neighbor Sampling on Zoom (no Interpolation)

By default (if this menu entry is unchecked), SM_GUI uses linear interpolation to calculate the pixel values for zoom stages greater than one. This ensures a smooth look of the image.

If you check this menu entry, nearest neighbor sampling will be used instead. This can be useful for diagnostics, because (1) you can clearly see the scan pixels and (2) the data values will be the same as in the scan (no interpolation).

Note that you can set the startup value of this setting in the config file (see Sec. 5.20).
