tances (greater than 10 feet or 3 meters).

Image Size
On the Size tab, modify the image prop-
erty settings as desired. Both keyboard and
stylus input are supported.
1. Use the Width and Height controls
to adjust the image.
• Width can be as much as 640
pixels.
• Height can be as much as 480
pixels.
Reducing the height and width
results in cropping of the image to
the center.
2. Use Scale to scale the image. Scal-
ing changes the x,y dimensions of the image. For example, scaling a
640 x 480 image to 50% results in an image size of 320 x 240. See
"Imaging Controls" on page
F-32 , for further information.
3. Rotate allows you to change the orientation of the image, in 90° incre-
ments.
Reducing the scale of an image results in reduced image size, which decreases
the time needed to capture an image.
