Source And Target Image Sizes - Epson PERFECTION 1240U Reference Manual

Source and Target Image Sizes

The Source fields indicate the size of the image that is displayed
or selected in the Preview window.
The Target fields indicate what size the image will be when it is
output.
Note:
The image size setting is closely related to the Resolution. If you change
either setting arbitrarily, the resulting image may not be what you
expect.
Width and Height menu:
The width and height of an image are indicated in the selected
unit of measure. You can type new values directly in the indicator
fields, or you can change the image area in the Preview window
by creating a marquee, or frame. Do this by dragging the mouse
over the desired area. See "Previewing Images" on page 3-3 for
more information on marquees.
