TrueType fonts
A font specification developed by Apple. TrueType fonts print the way they appear on the screen and can be resized to any height.
TWAIN
By using the TWAIN driver supplied by the manufacturer of the imaging hardware, Corel graphics applications can acquire images directly
from a digital camera or scanner.
two-point perspective
An effect created by lengthening or shortening two sides of an object to create the impression that the object is receding from view in two
directions.
U
underexposure
Insufficient light in an image.
See also exposure.
uniform fill
A type of fill used to apply one solid color to your image.
See also fill.
Unicode
A character encoding standard that defines character sets for all written languages in the world by using a 16-bit code set and more than
65, 000 characters. Unicode lets you handle text effectively regardless of the language of the text, your operating system, or the application
you are using.
URL (Uniform Resource Locator)
A unique address that defines where a webpage is located on the Internet.
V
vanishing point
A marker that appears when you select an extrusion or an object to which perspective has been added. With an extrusion, the vanishing
point marker indicates the depth (parallel extrusion) or the point at which the extruded surfaces would meet if extended (perspective
extrusion). In both cases, the vanishing point is indicated by an X.
vector graphic
An image generated from mathematical descriptions that determine the position, length, and direction in which lines are drawn. Vector
graphics are created as collections of lines rather than as patterns of individual dots or pixels.
See also bitmap.
vector object
A specific object within a drawing that is created as a collection of lines rather than as patterns of individual dots or pixels. Vector objects are
generated from mathematical descriptions that determine the position, length, and direction in which lines are drawn.
W
watermark
A small amount of random noise added to the luminance component of the image pixels which carries information about the image. This
information survives normal editing, printing, and scanning.
weld
To combine two objects into a single curve object with a single outline. A source object is welded to a target object to create a new object
that takes on the fill and outline attributes of the target object.
white point
The measurement of white on a color monitor that influences how highlights and contrast appear.
