Image Processing Library Reference Manual
Glossary-4
palette colors Colors specified by a palette, or lookup table.
The Image Processing Library uses palette
colors only in operations of image conversion to
and from absolute colors. See absolute colors.
PhotoYCC* A Kodak* proprietary color encoding and image
compression scheme. See YCC.
pixel depth The number of bits determining a single pixel in
the image.
pixel-oriented ordering Storing the image information in such an order
that the values of all color channels for each
pixel are clustered; for example, RGBRGB... .
See “Channel Sequence” in Chapter 2.
plane-oriented ordering Storing the image information so that all data of
one color channel follow all data of another
channel, thus forming a separate “plane” for
each channel; for example, RRRRRGGGGG...
region of interest An image region on which an operation acts
(or processing occurs).
RGB Red-green-blue. A three-channel color model
that uses red, green, and blue color channels.
RGBA Red-green-blue-alpha. A four-channel color
model that uses red, green, blue, and alpha (or
opacity) channels.
ROI See region of interest.
saturation A quantity used for measuring the purity of
colors. The maximum saturation corresponds to
the highest degree of color purity; the minimum
(zero) saturation corresponds to shades of gray.
scanline All image data for one row of pixels.
standard gray palette A complete palette of a DIB image whose red,
green, and blue values are equal for each entry
and monotonically increasing from entry to
entry.
three-channel model A color model that uses three color channels; for
example, the CMY color model.
