• Set the value for Width to 5.
• Next, you have to set the ofset. If you don't, the image will be cropped

inches, you must set the Offset X value to -0.125 inches because 0.125 is
half of 0.25 inches. Alternatively, you can click the
Center
button to center
and crop the image equally on both sides. Or you can select the image
