This glossary defines terms and concepts used in this manual. For
readers who are new to scanning, imaging, and character recog-
nition concepts, this glossary may be useful not only as a refer-
ence, but also as a primer on optical character recognition
technology.
Some definitions provided here contain terms in bold letters.
This means that these terms are also defined elsewhere in the
glossary.
A
annotation —A text note, arrow, circle, stamp, or other object
added to a Pagis document to point out (annotate) some item in
the document.
automatic document feeder (ADF) —An attachment to a
flatbed scanner that allows multiple pages to be loaded at one
time, and automatically scanned.
auto-orientation —In Pagis Pro, a capability to rotate a scanned
page so that it is oriented correctly. For example, if you scanned a
document upside-down in your scanner, Pagis Pro often can
detect and correct this before creating the Pagis document.
B
binary —In the context of a page image, refers to a black and
white, as opposed to color or grayscale , image.
bit depth —The number of bits of data used to store the color of
one picture element, or pixel , of an image. For example, a black
and white image has a bit depth of 1 (0=white, 1=black).
Grayscale and color data is stored at higher bit depths—4, 8, 16,
24, and 32 bits per pixel.
Brightness —See scanner brightness.
