if there is no selection, the maximum input size, measured from the
upper left corner of the image in the Preview Area and based on the
current paper size. To change the Width and Height settings, click the
Crop button on the toolbar and select a section of the image in the
preview area, or just type the desired dimensions into the Width and
Height text boxes.
• Units Click the down-arrow and select a unit to measure the

and Height proportions. If you change Width or Height, the other

the original image. As you enlarge or reduce the selection, note that
the Width and Height of the selection remain in correct proportion.
