reset color. The color of a presentation space before
any data is added to it. Synonymous with color of
medium.
resident resource. In the IPDS architecture, a
resource in a printer or in a resource-caching
intermediate device. A resident resource can be
installed manually or can be captured by the device if
it is intended for public use. A resident resource can
not be removed by a presentation services program.
A resident resource is referenced by a global ID that
is valid for the duration of the resource's presence in
the device. Contrast with downloaded resource.
resolution. (1) A measure of the sharpness of an
input or output device capability, as given by some
measure relative to the distance between two points
or lines that can just be distinguished. (2) The
number of addressable pels per unit of length.
resource. An object that is referenced by a data
stream or by another object to provide data or
information. Resource objects can be stored in
libraries. In the MO:DCA architecture, resource
objects can be contained within a resource group.
Examples of resources are fonts, overlays, and page
segments. See also downloaded resource and
resident resource.
retired. Set aside for a particular purpose, and not
available for any other purpose. Retired fields and
values are specified for compatibility with existing
products and identify one of the following:
Fields or values that have been used by a product
•
in a manner not compliant with the architected
definition
Fields or values that have been removed from an
•
architecture.
RM4SCC. See Royal Mail 4 State Customer Code.
root segment. A segment in the picture chain that is
not called by any other segment. If a single segment
that is not in a chain is drawn, it is treated as a root
segment for the duration of the drawing process.
rotation. The orientation of a presentation space with
respect to the coordinate system of a containing
presentation space. Rotation is measured in degrees
in a clockwise direction. Zero-degree rotation exists
when the angle between a presentation space's
positive X axis and the containing presentation
space's positive X axis is zero degrees. Contrast with
character rotation.
Royal Mail 4 State Customer Code (RM4SCC). A 2
dimensional bar code symbology developed by the
United Kingdom's Royal Mail postal service for use in
automated mail-sorting processes.
rule. A solid line of any line width.
S
sans serif. A type style characterized by strokes that
end with no flaring or crossing of lines at the
stroke-ends. Contrast with serif.
scaling. Making all or part of a picture smaller or
larger by multiplying the coordinate values of the
picture by a constant amount. If the same multiplier
is applied along both dimensions, the scaling is
uniform, and the proportions of the picture are
unaffected. Otherwise, the scaling is anamorphic, and
the proportions of the picture are changed. See also
anamorphic scaling.
scan line. A series of picture elements. Scan lines in
raster patterns form images. See also picture
element and raster pattern.
scanner. In bar codes, an electronic device that
converts optical information into electrical signals.
See also reader.
section. A portion of a double-byte code page that
consists of 256 consecutive entries. The first byte of
a two-byte code point is the section identifier. A
code-page section is also called a code-page ward in
some environments. See also code page and code
point.
section identifier. A value that identifies a section.
Synonymous with section number.
section number. A value that identifies a section.
Synonymous with section identifier.
secure overlay. An overlay that can be printed
anywhere within the physical printable area. A
secure overlay is not affected by an IPDS Define User
Area command.
segment. (1) In GOCA, a set of graphics drawing
orders contained within a Begin Segment command.
See also graphics segment. (2) In IOCA, image
content bracketed by Begin Segment and End
Segment self-defining fields. See also image
segment.
segment prolog. The first portion of a segment's
data. Prologs are optional. They contain attribute
settings and drawing controls. Synonymous with
prolog.
segment transform. A model transform that is
applied to a whole segment.
semantics. The meaning of the parameters of a
construct. See also pragmatics and syntax.
sequential baseline. A conceptual line with respect to
which successive characters are aligned. See also
character baseline. Synonymous with baseline and
printing baseline.
