Background processing:
Tasks or programs that execute without user intervention, freeing you to work on other tasks.
Banding:
A disruption in the gradation of colors in a digital image. Banding can also occur when printing images on a multi-pass color printer.
Bandwidth:
The amount of data that can be sent through a network connection in a fixed amount of time. Bandwidth is measured in Kilobits per second (Kbps).
Batch processing:
Operations performed to more than one image at a time. For example, resizing a group of images. ACDSee can perform a wide variety of batch processing functions.
Bezier Curve:
A smooth curve specified by a small set of values, including tangent and control point information.
Bicubic Interpolation:
A zoom method that resamples the image before showing the image again to allow for greater detail to be shown.
Bi-level:
An image that contains only two colorsa background color and a foreground color. For example, a black and white image.
Bitmap (BMP):
An image made up of dots, or pixels. Refers to a raster image, in which the image consists of rows or pixels rather than vector coordinates.
Bitonal:
See bi-level.
Brightness:
The light intensity of an image. You can make an image appear brighter or darker by adjusting the brightness.
Buffer:
A temporary storage area usually held in RAM. The purpose of a buffer is to act as a temporary holding area for data that will allow the CPU to manipulate data before transferring it to a device.
Byte:
An ensemble of eight bits of memory in a computer.
