If you have established the image data with Check
resolution/Set dot size
, then this field shows the current
vertical resolution of the graphic in dpi or points cicero (pc). You
can also click on the numerical field, clear the existing entry with
[Esc] and type in a different resolution, terminating input with
[Return]. Note that while the vertical resolution need not be the same
as the horizontal resolution, better results will be achieved if they
are equal.
