Changing the Size of the Scanned Image
When you scan an image using the default settings, the output image is
scanned at the same size and proportion as the original image. However,
SilverFast Lite lets you change the size of the output image, either by
changing the scale of the original or by setting the size of the final image.
The relationship between the size of the framed original, the scale, and
the output size is:
Frame size × Scale = Output size
For example, a 2 × 3-inch frame with a scale of 200% makes your
scanned output size 4 × 6 inches. It also increases your scan resolution
by 200% to retain image quality; see Changing the Resolution
for details.
The Output box displays the size of the framed original (input size), the
scale percentage, and the size of the scanned image (output size):
Scaling changes the
actual output size;
zooming changes
only the view on your
screen.
