Proportional scaling
applies to changes
made to either the
input frame size or
the output size.
Basic Scanning
These sections give various ways to change your image size:
Resizing with the Mouse
Maintaining Size Ratio (Proportional Scaling)
Maintaining Output Size
Resizing by Manually Entering Output Dimensions
Resizing by Manually Entering a Scale Percentage
Resizing with the Mouse
To resize an image using the mouse:
1 Click on a frame if there's more than one displayed.
2 Click and drag the corner or edge of the frame until the output size is
what you want.
Maintaining Size Ratio (Proportional Scaling)
If you were to scale the width on an image differently from the height, the
scanned image would look stretched or distorted. Proportional scaling
keeps the proportions of an image (width and height) the same when
enlarging or shrinking the image.
When you use proportional scaling and you change the width or height of
an image, SilverFast Lite automatically adjusts the other dimension to
maintain the same width-to-height ratio.
