Faxing images: Any image you intend to fax from a PC-based fax
modem should be scanned at 200 dpi. Fax machines only receive
images at 200 dpi, and some programs may fault if you try to scan at
higher resolutions.
Refer to the chart below for resolution setting guidelines.
IC = InfoCenter, IPG = Image Pals GO!
Scale
Scaling allows you to specify an image size before scanning. This op-
tion is useful because it allows you to control the image file size - thus
minimize scanning time and occupied disk space. It also eliminates
the neccesity to change the images size after it is transferred into an-
other application.
Inverse
This command reverses an image’s display. Black pixels will be white,
and white pixels will become black. The resulting image is like a photo
negative of the original.
Brightness and Contrast
These controls adjust the brightness and contrast of the image you
are about to scan. Increasing the contrast will sharpen the image by
excagerating the images colors or tones. Increase the brightness to
lighten the image and compensate for the contrast selection.
Experiment with these controls to determine the look you prefer.
Usually these controls are adjusted together in a 2:1 ratio of
brightness to contrast.
