4.3 Resolution Control
Resolution: A good control of the resolution results a
satisfactory detail of an image. The resolution is measured by
dots per inch(dpi). Normally the greater the dpi number, the
higher the resolution and the image file size. Yet 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.
