J
JPEG—Pronounced JAY-peg, this is a compressed graphic image
format. It is created by choosing from a range of compression
qualities (actually, from one of a suite of compression algorithms).
When a JPEG is created or converted from another image format,
some trade-off is made between image quality and file size.
Formally, the JPEG file format is ISO standard 10918. JPEG is a
file type supported by the World Wide Web protocol, usually with
the file suffix of .jpg. Pagis Pro uses JPEG compression in the
color image layer of XIF files.
K
keyword—A word assigned to a file for search and retrieval
purposes.
L
landscape orientation—Describes a page on which lines of
print flow across the wider dimension (or length) of the page. This
is opposed to portrait pages, on which lines of print flow across
the more narrow dimension (or width) of the page. For example,
many office documents are printed on 8.5-by-11 inch paper. With
landscape orientation, the page is rotated 90 degrees and print
flows across the 11-inch dimension of the page.
N
native user interface—See TWAIN Interface.
Noise—Extraneous dots in a scanned image typically caused by
dirt, ink marks, stains or bleed-through on the printed original.
O
optical character recognition (OCR)—A technology that
analyzes binary images of character shapes, identifies them as
particular characters, and outputs them to a text data stream,
either in computer memory or to a computer file. See also
recognition.
