How to adjust the resolution and dimension of an image
Now you have chosen an image with appropriate image size and
aspect ratio according to our discussion above, the next step is
to adjust the resolution and dimension of the source image.
The easiest way to adjust image resolution and dimension is to
use the Adjust function provided by your application software.
For example, now you have an image with resolution at 120dpi
and dimension of 8” x 10”, and you want to make a full-size (4”
x 5”) print on the paper in portrait mode at 300x300 dpi:
1. On the Command Panel, click “Edit”, then “Adjust”.
2. Click “Size” on the Tool Bar.
3. On the Options Panel, click User Defined and Keep
aspect ratio and then key in the dimension you want the
image to be resized into. Since we want to make a full-size
print on the paper with FotoPrisa Printer, in this case, enter
Width=4, and Height will be set to “5” automatically
(because the aspect ratio is kept fixed) and set the Unit to
“Inch”.
4. Set the Resolution. In this case, enter 300 and set the unit
to Pixels/In.
5. Click Apply to finish.
