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.
In image correction, the white point determines the brightness value that is considered white in a bitmap image. In Corel PHOTO-PAINT, you
can set the white point to improve the contrast of an image. For example, in a histogram of an image, with a brightness scale of 0 (dark) to
255 (light), if you set the white point at 250, all pixels with a value greater than 250 are converted to white.
Windows Image Acquisition (WIA)
A standard interface and driver, created by Microsoft, for loading images from peripheral devices, such as scanners and digital cameras.
Z
zoom
To reduce or magnify the view of a drawing. You can zoom in to see details or zoom out for a broader view.
ZIP
A lossless file compression technique that results in smaller file size and faster processing time.
