Bits Per Pixel
Three levels of bits per pixel are offered: 1 bit/pixel for black and white,
8bits/pixel for gray scale, and 24 bits/pixel for color.
Brightness
The brightness slider bar varies the brightness of the image, ranging from darkest
on the left to lightest on the right.
Threshold
The threshold slider bar allows you to select the level, below which all pixels are
set to black, and above which all pixels are set to white. Moving the slider bar
setting to the right increases this threshold level.
Photo Invert
Selecting this control will let you scan the “negative” of your images.
Document Size
In selecting the size of the area to be scanned, the following standard document
sizes are typically offered:
• letter
•A5
• A5 (land)
•A4
•B5
All document sizes are in portrait mode (narrower side on top), unless indicated
by a “land” designation.
X0, Y0, Width, Height
The document size may also be set manually, either by dragging a rectangle in
the preview area or by entering the settings directly into the X0, Y0, Width, and
Height text fields. The setting units may be specified as Inches, Millimeters, or
Pixels (“Pels”).
