BIND
To align the baseline of text so it follows the contours of a
path.
BITMAP
A digital image composed of pixels (.bmp); technically, an
image containing only black and white (see also image,
page G.765).
BITMAPPED FONT
A font made up of characters composed of pixels,
rather than vector data. Fonts displayed on a computer screen are bit-
mapped fonts, for example, and usually arent suitable for printing.
BLACK AND WHITE
A method of digital imaging that uses pure black
and pure white pixels. The frequency of black or white pixels create
the illusion of shades.
BLEND
A smooth transition of shape and color between two vector
objects through intermediate objects created by Canvas.
BOUNDING BOX
An invisible rectangle that defines the boundaries
of an object. Canvas displays an objects bounding box when the
object is selected.
BULLET
A special text character, usually a filled circle (), available
in many fonts, especially symbol fonts.
BUTTON
A pushbutton-like image in dialog boxes where you click
to designate, confirm, or cancel an action.
CANVAS TEMPLATE
A Canvas document that includes options and
settings and is used as the basis for new documents.
CCITT
Consultative Committee on International Telegraphy and
Telephony; its standards include data transmission formats.
CENTER EXTENSION
The distance that Center dimension lines
extend beyond the dimensioned object.
CENTER GAP
The space between a Center dimension crosshair and
the lines that extend from it.
CENTER LENGTH
The Center dimension crosshair length.
CHANNEL
In digital images, a layer of primary color in a full-color
image. For example, an RGB image has at least three color channels
(one each for red, green, and blue) and a composite channel, which
adds the three channels together to create a full-color image.
CHANNEL MASK
A channel that creates transparency based on the
the luminance of pixels in the channel. It can be applied to any type
of object.
CHARACTER
Any symbol, such as letters, numbers, and punctuation,
that can convey information. Some characters can be displayed on
the monitor screen and printed on a printer.
CHARACTER STYLE
A set of attributes, such as color, typeface, and
style, that can be applied as a group to text characters.
