Changing the Size of the Scanned Image Scaling changes the actual output size; zooming changes only the view on your screen. 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): the size relationship (width and height) between the original and the scanned image the width and height of the framed original the image file size the proportional scaling lock bracket locks the width-to-height ratio click this button to switch units of measurement between inches and centimeters the output size lock locks the final output size Basic Scanning Page 30
