glyph (typographic)
A typographic glyph corresponds to a single character of a typeface.
grab area
The area of a command bar that can be dragged. Dragging the grab area moves the bar, while dragging any other area of the bar has no
effect. The location of the grab area depends on the operating system you are using, the orientation of the bar, and whether the bar is
docked or undocked. Command bars with grab areas include toolbars, the toolbox, and the property bar.
grayscale
A color mode that displays images by using 256 shades of gray. Each color is defined as a value between 0 and 255, where 0 is darkest
(black) and 255 is lightest (white). Grayscale images, especially photos, are commonly referred to as “black and white.”
greeking
A method of representing text by using either words that have no meaning or a series of straight lines.
grid
A series of evenly spaced horizontal and vertical lines that are used to help draw and arrange objects.
See also document grid.
group
A set of objects that behave as one unit. Operations you perform on a group apply equally to each of its objects.
guideline
A horizontal, vertical, or slanted line that can be placed anywhere in the drawing window to aid in object placement.
gutter
The space between columns of text, also called the alley. In printing, the white space formed by the inside margins of two facing pages.
H
halftone
An image that has been converted from a continuous tone image to a series of dots of various sizes to represent different tones.
handles
A set of eight black squares that appear at the corners and sides of an object when the object is selected. By dragging individual handles,
you can scale, resize, or mirror the object. If you click a selected object, the shape of the handles changes to arrows so that you can rotate
and skew the object.
highlight, shadow, and midtone
Terms used to describe the brightness of pixels in a bitmap image. Brightness values range from 0 (dark) to 255 (light). Pixels in the first
third of the range are considered shadows, pixels in the middle third of the range are considered midtones, and pixels in the last third of
the range are considered highlights. You can lighten or darken specific areas in images by adjusting the highlights, shadows, or midtones. A
histogram is an excellent tool for viewing and evaluating the highlights, shadows, and midtones of images.
histogram
A histogram consists of a horizontal bar chart that plots the brightness values of the pixels in your bitmap image on a scale from 0 (dark) to
255 (light). The left part of the histogram represents the shadows of an image, the middle part represents the midtones, and the right part
represents the highlights. The height of the spikes indicates the number of pixels at each brightness level. For example, a large number of
pixels in the shadows (the left side of the histogram) indicates the presence of image detail in the dark areas of the image.
hotspot
The area of an object that you can click to jump to the address specified by a URL.
hotspotting
The process of adding data to objects or groups of objects so that they respond to events, such as pointing or clicking. For example, you can
assign a URL to an object, making it a hyperlink to an external website.
