4.4 Resolution Control
A good control of the resolution results a satisfactory detail of
an image that scans. The resolution is measured by dots per
inch(dpi). Normally, the greater the dpi number, the higher
the resolution and the image file size. Be aware that the
greater resolution takes more time, memory and disk space,
therefore, up to a certain degree of dpi, the resolution will not
visually be improved, on the contrary, it makes your files
more unmanageable.
