Scaling

Scaling is the process of creating larger or smaller images in your scanning software so
that you need not resize the images later when they are delivered to your image-editing
program.
In the scanning software, scaling has an inverse relation to resolution: The lower the
resolution, the larger the image can be scaled. At the highest resolution, images can only
be scaled smaller.
To illustrate the use of scaling: Assume that your input dimensions are 4" x 5":
• If scaling is at 100%, output dimensions will also be 4" x 5".
• If scaling is at 50%, output dimensions will be halved — to 2" x 2.5"
• If scaling is at 200%, output dimensions will be doubled — to 8" x 10".
The above assumes that your resolution is held constant throughout the changes. When you
change resolution and specify a value that has no exact equivalent for scaling, the scaling
may be affected and adjusts itself to the nearest allowed value. For instance, if your resolution
is 100, your scaling becomes 99 (instead of a full 100), because that is the closest scaling
equivalent, given the resolution value.
