CONTENTS GLOSSARY INDEX Chapter 3 Scanning 34 When you click the Keep Proportions button, the image size is maintained in the same proportion whenever you change either the width or the height. Keep Proportions active For example, if you set the width to 4 inches and the height to 6 inches, and then you change the width to 5 inches, the height stays at 6 inches if the constraint is turned off, so the proportion of the image width and height changes. If you click the Keep Proportions button and then change the width, the height automatically changes to 7.50 inches. When the Keep Proportions button is selected, the image maintains the same ratio indicated in the Width and Height text boxes. To change size proportionally: 1. Click the Keep Proportions button. A chain appears between the Width and Height text boxes. 2. Click the Crop button on the toolbar and select part of the image in the preview area. When you enlarge or reduce the selection, notice that the image width and height stay in the same proportion. Setting Scale The Scale setting lets you specify an output size for the selected image as a percentage of the original width and height. The scale amount is preset to 100 percent. If you reduce the scale of an image that has a width of 7 inches and a height of 9 inches by 50 percent, the selection in the preview area and the values in the Width and Height text boxes remain the same, but the Output size changes to indicate the size of the image when it is acquired by the application. For example, if your preview image is 7 inches wide by 9 inches high, and you select a scale of 50 percent, the output image will be 3.5 inches wide by 4.5 inches high. 34

When you click the Keep Proportions button, the image size is maintained in
the same proportion whenever you change either the width or the height.
For example, if you set the width to 4 inches and the height to 6 inches, and
then you change the width to 5 inches, the height stays at 6 inches if the
constraint is turned off, so the proportion of the image width and height
changes. If you click the Keep Proportions button and then change the width,
the height automatically changes to 7.50 inches.
When the Keep Proportions button is selected, the image maintains the same
ratio indicated in the Width and Height text boxes.
To change size proportionally:
1.
Click the Keep Proportions button.
A chain appears between the Width and Height text boxes.
2.
Click the Crop button on the toolbar and select part of the image in the
preview area.
When you enlarge or reduce the selection, notice that the image width
and height stay in the same proportion.
Setting Scale
The Scale setting lets you specify an output size for the selected image as a
percentage of the original width and height. The scale amount is preset to
100 percent.
If you reduce the scale of an image that has a width of 7 inches and a height
of 9 inches by 50 percent, the selection in the preview area and the values in
the Width and Height text boxes remain the same, but the Output size
changes to indicate the size of the image when it is acquired by the
application. For example, if your preview image is 7 inches wide by 9 inches
high, and you select a scale of 50 percent, the output image will be 3.5 inches
wide by 4.5 inches high.
