HSB (hue, saturation, brightness)
A color model that defines three components: hue, saturation, and brightness. Hue determines color (yellow, orange, red, and so on);
brightness determines perceived intensity (lighter or darker color); and saturation determines color depth (from dull to intense).
HTML
The World Wide Web authoring standard comprised of markup tags that define the structure and components of a document. The tags are
used to tag text and integrate resources (such as images, sound, video, and animation) when you create a webpage.
hue
The property of a color that allows it to be classified by its name. For example, blue, green, and red are all hues.

image map
A graphic in an HTML document that contains clickable areas that link to locations on the World Wide Web, to other HTML documents, or
to graphics.
image resolution
The number of pixels per inch in a bitmap measured in ppi (pixels per inch) or dpi (dots per inch). Low resolutions can result in a grainy
appearance of the bitmap; high resolutions can produce smoother images but result in larger file sizes.
imagesetter
A high-resolution device that creates film or film-based paper output used in the production of plates for printing presses.
insert
To import and place a photo image, clipart object, or sound file into a drawing.
intensity
Intensity is a measure of the brightness of the light pixels in a bitmap compared with the darker midtones and dark pixels. An increase in
intensity increases the vividness of whites while maintaining true darks.
interlacing
In GIF images, a method that lets you display a web-based image on the screen at a low, blocky resolution. As the image data loads, the
image quality improves.
isometric
A type of projection characterized by three axes at right angles. Objects can be represented as three-dimensional by projecting them. A
square becomes one of the faces of a cube when it is projected. Isometric projections use angles that are increments of 30 degrees.
J
JavaScript
A scripting language used on the web to add interactive functions to HTML pages.
JPEG
A format for photographic images that offers compression with some loss of image quality. Because of their compression (up to 20 to 1)
and small file size, JPEG images are widely used in Internet publishing.
