Glossary

active document

The document displayed in the active document window, affected by the View and other commands. A document can appear in more than one document window at once. As long as one of those windows is active, the document itself is active.

active document window

This window appears "on top" of all other document windows (unless tiled), and its title bar is a different color. It contains one view of the active document, the one to which the chosen commands apply. To activate a window, click in its title bar.

active edit layer

The "top" edit layer, the one that can be marked up and edited. Selected with the Layer $image\lgarrow_shg.gif$ Active command or the Layers window.

active multipage

An active document that happens to be a multipage document. See current multipage.

active raster layer

The raster layer that is affected by the Raster menu commands and can be cut, copied, and pasted. Selected with the Layer $image\lgarrow_shg.gif$ Active command or the Layers window.

algorithm

A prescribed set of well-defined steps used to solve a problem or conduct an operation.

annotation

A textual note placed on an image, signified by an icon: $image\draw_ann_shg.gif$ . You place annotations with the Annotation tool.

API

Application programming interface. The API allows programmers to integrate Imagenation with other programs, to control the program remotely, and to customize the user interface.

arc

A vector object in the shape of a chord of a circle. A "chord" is a straight line connecting two points on a curve or a curved surface.

aspect ratio

The relationship of width to height. When aspect ratio is maintained, the image is scaled proportionally. When it is not, the image is "stretched" vertically or horizontally when scaled.

attributes

The characteristics (size, appearance, format, orientation, and so on) of an existing object, layer file, or page file.

banner

A text string, similar to a header or footer in a word processing program, that can be printed, faxed, or merged at the top or bottom of each page. The banner appears outside the image boundaries. Compare stamp.

bilevel raster

Black-and-white image. A raster image in which data is stored as one data bit for one dot (or pixel) of raster data. The data is either on or off (black or white) with no intermediate status.

bitmap

A raster image, a collection of dots called pixels that make up an image.

cap

The end point of an object line. It can be rounded or squared.

CFG file

A CFG file is a configuration file. Configuration files define whether certain menus, commands, and icons are displayed. Normally you would just use the CFG file that matches your edition (for example, the OVA CFG file for the Office-View-Annotate edition of Imagenation). You can, however, select another CFG file to use. You can also edit the CFG file if you have the Imagenation SRC file. See SRC file.

check boxes

The settings in dialog boxes that can be selected ( ţ or x ) and cleared (o).

CLF document

See Spicer Multilayer Page (.clf).

CMC

CMC = computer-mediated communicaton. E-mail programs can be CMC-compliant.

color raster

A raster image in which combinations of red-green-blue (RGB) form the color pixels.

command line

The command line instructs an operating system (such as MS-DOS or Windows) to carry out a command or to run a program. It consists of the command name followed by a list of arguments specific to it.

compression

A technique for making raster data sizes smaller, so that they consume less RAM and disk space. A raster file in its native or raw form is uncompressed. Compression is achieved by applying mathematical algorithms to the data storage process.

configuring

Defining the default attributes.

current multipage

The displayed portion of the active multipage, whether or not that is an embedded page.

current page

The page displayed in the active document window that is affected by the commands. Its title bar is displayed in reverse field.

See Spicer Multipage (.das).

data format

See file format.

defaults

Preset conditions and attributes that determine the operation of Imagenation. The default value is automatically assigned unless you specifically request another one. See preferences and options.

deselect

To "turn off" an object or file that is selected so that it is no longer ready to be altered. See select.

deskewing

Straightening a crooked raster image.

despeckling

document types

The classification of documents according to the data they contain. Imagenation can read raster, vector, and text document types, in certain formats. Raster files are made up of dots, vector files of objects and equations, and text files of text with formatting.

These basic document types are combined to create other document types: multilayer page documents, multipage documents, and sets.

dpcm, dpi

Dots per centimeter, Dots per inch. All are measures of image resolution. See resolution.

Erase Area

An eraser tool that erases in a specified shape--box, circle, ellipse, or polygon. The "erase" is created by drawing on the active edit layer in the background color, which hides the underlying layers. The erased area is not copied. See also Rubout.

Circular erased area: $image\erasarea_shg.gif$
