Image Dimension controls
These controls allow you to adjust the various factors that affect the image,
including the width and height of your image when it is first scanned (Scan
Frame), the scaling factor, and the dimensions of the image in final output.
1. Scan Frame (input) x Scaling = output: This mathematical formula
indicates the relation of the input dimensions to scaling and how these
factors affect image dimensions when the image is scanned.
To use the Image Dimension Controls:
• Select the unit of measurement.
• Enter a value in the applicable edit boxes (width input, height input,
scaling, width output, height output).
• Scan Frame width and Scan Frame height refer to the dimensions of
the scan frame that you draw. For example, if the image on your
scanner is 5" x 7" and you draw a scan frame that is 3" x 4", then your
Scan Frame width will show 3.000 and your Scan Frame height will
show 4.000.
The Scan Frame width, Scan Frame height, output width, and output
height are affected by your scaling and whether you have checked the Keep
Proportion option or not.
2. The Keep Proportion option allows you to keep the ratio of the image
width and height constant.
3. The Scaling control lets you create large or small images so that the images
don't have to be resized subsequently, which is usually done in your image-
editing software. For more details, see the Basic Concepts chapter and the
Scaling section in the following pages.
