Using Marquees

A marquee is a frame around an entire image, or a portion of an image so
you can sc an only the mo s t important part. You can even create multip le
marquees on one or mo re im ages and scan them one at a time, if your
applicat ion software s upports mu lt iple image windows .

To create a marquee, follow these steps:
1 Move the mouse pointer over the im age in the Preview wi ndow. The

pointer bec omes a cro s s h air.

2 Position th e pointer in the c orner of the area you w ant to select and

press the m ouse butto n.

If you need to adjust the marquee size or position, see Resizing and

Moving Marquees. To create additional marquees, see Creating Mu lti ple
Marquees. To de let e or duplica t e a m arquee , see Deleting a nd
Duplicating Marqu ees.

Resizing and Moving Marquees

To resize a marquee, place the mouse pointer over any of the eight boxes

To move a marquee, place the mouse pointer anywhere on the edge of
the marquee. The pointer changes to a hand. Click the mouse button and
drag the ent ire marque e t o m ove it where yo u w ant it.

To limit mo ve m ent of the marquee to vertical or h oriz ontal mov em ent,
