Glossary
absolute cursor position A position of the cursor in the page buffer
that is referenced to the upper left corner of the document (X,Y
coordinates = 0,0). See also cursor and relative cursor position.
ASCII American Standard Code for Information Interchange.
A standard 7-bit code used to represent a set of characters numbered
0-127. Extended, or 8-bit, ASCII adds characters 128-255. ASCII is
usually used on PCs, workstations, and most minicomputers.
baseline An imaginary line on which characters sit. Used in category II
font design to allow for different sizes of characters on the same line.
big-endian A computer architecture in which, within a given multi-byte
numeric representation, the most significant byte has the lowest address
(the word is stored “big-end-first”). Most processors, including the IBM
370 family, the PDP-10, the Motorola microprocessor families, and most
of the various RISC designs current in mid-1993, are big-endian.
bitmap An arrangement of dots that represents text or graphics.
A computer uses the dots in an arrangement of binary 1s and 0s to
represent the presence and absence of ink drops and sends this data to
the printheads.
bounding box An imaginary rectangle that encloses a character
image. The rectangle includes only the dots used to make the image.
Spacing around the image is not included. See also character cell.
bpi Bits per inch. A measure of tape density giving the number of bits
that can be recorded on 1 inch (25mm) of magnetic tape.
category I font A KODAK VERSAMARK font that defines characters in
cells that include character and line spacing. Character cells cannot
overlap. Line escapement is in the positive Y direction only. See also font.
category II font A KODAK VERSAMARK font that defines characters in
bounding boxes that contain only the character image. Character
definitions allow both positive and negative X and Y character
escapements and offsets. Line escapement is defined using positive and
negative X and Y values. This font category permits character
overlapping, vertical printing, and right-to-left printing. See also font.
character cell An imaginary rectangle that encloses a character image
and surrounding space. The area can include white space for characterto-character
and interline spacing. See also bounding box.
character escapement The distance the cursor is moved from its
position for the present character to its position for the next character.
The cursor can be moved in both the X and Y dimensions in positive or
negative directions. Character escapement values are specified when
defining the font.
