Paintbrush bitmap image standard.
Photo
CD
 Kodak announced the concept of the Photo CD System to
the world in late September of 1990. It was originally introduced
as a means whereby the consumer could store his or her pictures
on a convenient, compact disc and view them easily on any television
set.
As
initially conceived, a PCD file -- or Image Pac -- could be created
from any 35mm color or black and white negative or color slide.
After conventional processing, the film is scanned and digitally
written to a Photo CD disc. Each disc holds approximately 100
images. A thermal index print with a file access number for each
image is intended to simplify image selection for viewing on a
television set with a Photo CD player or on the monitor of a computer
with a CD-ROM X drive.
PICT
The
native bitmapped file format for Macintosh images.
Picture
Physical
resemblance or realistic depictions of persons, places, or things
in the form of photographs, drawings, etc.
Pixel
Short
for "picture elements," the pixel is the smallest part
of a digitized or digital image.
Also used in measuring image size and resolution, i.e., 640 X
480 is the pixel resolution of most VGA Monitors. (Note pixels
are square in computers and rectangular in video)
Pixelization
The
stair-stepped appearance of a curved or angled line in digital
imaging. The smaller the pixels, and the greater their number,
the less apparent the "pixelization" of the image. Also
known as the "jaggies".
Plug-In
The
plug-in architecture was first popularized by Adobe Photoshop
and is now the defacto standard for all major imaging programs.
Unlike Twain it allows more flexibility in design so acquire,
export, and specific task can be performed with in a software
application. This is the preferred choice of operation in the
Macintosh and 'Power User' computers. Plug-In ideology has spread
to other applications like Netscape Navigator, Macromedia Director,
and so on. Not all plug-ins work with all products, specific interfaces
are required for different types of software. Adobe has become
the defacto standard for image editing software, and graphic illustration
software.
PPI
Printing
term for Pixels per Inch
Programming
code, Programming Language
A
formal language in which computer programs are written. The definition
of a particular language consists of both syntax (how the various
symbols of the language may be combined) and semantics (the meaning
of the language constructs).
