Objected-oriented (mode): the Draw
graphics mode. A set of algorithms describe graphic
form in abstract geometrical terms, as object primitives,
the most fundamental shapes from which all other shapes
are made: lines, curves, and solid or patterned areas.
Oblique type: characters that
are slanted to the right; sans serif typefaces often
have oblique rather than true italics, which are
a separate font.
Offset printing: for high-volume
reproduction -- utilizes three rotating drums: a
plate cylinder, a blanket cylinder, and an impression
cylinder. The printing plate is wrapped around the
plate cylinder, inked and dampened. The plate image
is transferred, or offset, onto the blanket cylinder.
Paper passes between the blanket cylinder and the
impression cylinder, and the image is transferred
onto the paper.
One-point perspective: An effect
created by lengthening or shortening one side of
an object to create the impression that the object
is receding from view in one direction.
Opaque: The inability to see through
an object. If an object is 100% opaque, you cannot
see through it. Opacity levels under 100% increase
the ability to see through objects.
Origin: The point in the drawing
window at which the rulers intersect
Outline: The line that defines
the shape of an object
Output resolution: The number
of dots per inch (dpi) that an output device, such
as an imagesetter or laser printer, produces.
Overexposure: Excessive light
in an image that gives it a washed-out appearance
Orphan: in a page layout, the
first line of a paragraph separated from the rest
of the paragraph by a column or page break. Headings
without enough type under them may be considered
as orphans; there should be as much type below the
heading as the height of the heading itself, including
white space.
