Adjusting Dashed-line Border of Scanned Image
To adjust the dashed-line box around the scanned image, use
your mouse to make the cursor hover over the line of one side of the box until a
double-headed black arrow appears.
Hold down the left button of your mouse and move the mouse to
adjust the line. Use the black arrow to either move the line closer to or
farther away from the text.
Repeat this action on all four sides of the box until you cut
out most of the white space from around the text, but be sure to leave at least
a small margin around the text.
In the picture below, please note the dashed-line box and the
margin around the text (see Figure 1).
