Image Dimension Controls - Microtek ScanMaker IIG User Manual

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 (input), the scaling factor, and
the dimensions of the image when it is finally output.

1 This is a mathematical formula expressing the relation of the input dimensions to
scaling and how these factors affect image dimensions when the image is scanned.
• Input width and input 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 input width will show 3.000 and your input height
will show 4.000.
• Output width and output height refer to the dimensions of the image when output
to an output device (such as a monitor or printer).
The input width, input height, output width, and output height are affected by your
scaling and whether or not the Aspect Lock is on. For more details, see the sections
How to use Input-Output dimensions and How to use the Aspect Lock.
2 The Aspect Lock allows you to keep the ratio of the image width and height constant.
(For more details, see the section How to use the Aspect Lock in the following pages.)
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.
4 The Unit of Measurement allows you to select your unit of measure. The options
include inch, centimeter (cm), millimeter (mm), point, and pixel.
5 The Size indicates how big the file will be when you accept the dimensions shown in
the edit boxes, together with the resolution setting that you selected. Size is calculated
automatically.
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).
