Although the ratio of scanned pixels to output halftone dots is traditionally
2:1, ratios as low as 1:1 can be acceptable in certain applications. We recommend
1.5:1 for most medium to high resolution four color offset reproduction. The final
image size and resolution are specified through a combination of selecting a crop
in the preview area and typing scan parameters into the editable text items. The
plugin will constantly check what you are typing and limit it based on the
maximum crop size and scan resolution.
The behavior of the controls can be changed by checking the Proportions or
File Size checkboxes. If the File Size checkbox is checked, the Proportions
checkbox will automatically be checked.

There are different approaches that can be taken when defining the final image.
By Crop Area: To scan an image that includes specific elements of the image,
select a crop in the preview area and check the Proportions checkbox. This will
allow you to change the width, height, resolution and pitch in any way without
modifying your selection.
