An acronym for “picture element,” a pixel is the smallest element

used to create a screen image. It can contain up to 24 bits of color

information.

Platen

scanning.

Preset Curves

A set of curves designed to fix common photographic image

problems such as underexposure, overexposure, or low contrast.

Preview Area

The area located to the left of the ScanGear CS main window

where the image is displayed before the scan occurs. When you

click the Preview button, the image on the scanner is scanned into

the Preview Area, but not acquired by the application.

Preview Image Cache

When the preview image cache feature is switched on, the image

in the Preview Area is saved and displayed the next time ScanGear

CS is launched from the parent software application. To switch

this feature on and off, open the Preferences sheet and click the

button for “Saved image will be displayed”.

Proportion

The ratio of width to height. When you click the Keep Proportions

button, the image size is maintained in the same proportion

whenever you change either the width or the height.
