B
bit map
A representation of a graphic in computer memory consisting of rows and
columns of dots. Bit-mapped graphics, saved using the BMP file extension, are
often referred to as raster graphics.
blackpoint
Increases the blackness of the dark areas of an image.
C
cached items
Cached items are stored in a database file to preserve metadata information (such
as image properties) or so that thumbnails can be quickly displayed in the File list
(rather than the program regenerating thumbnails each time you browse images).
Cached information does not include digital camera information and image
descriptions.
captions
Text insertions used with Slide Show (with transition effects).
clipboard
The clipboard is used for cutting and pasting. Before the item is copied to another
location it is temporarily stored in a special file or memory area (buffer) called the
clipboard. For example, if you copy an image, ACDSee copies it to the clipboard;
when you paste the image, ACDSee copies it from the clipboard to the destination
of your choice.
color channel value
Contains all of the pixel information for a single color. A grayscale image has one
channel, an RGB image has three channels.
color depth
The number of colors that an image contains.
command line arguments
The most recently displayed command prompt and the line on the display screen
where a command is expected. A command line can be entered from the Run line
found in the Start menu but it is more typically used in batch files (.bat or .cmd
files).
contrast
The difference in brightness between the light and dark areas of an image.
