Vector graphics: the use of
geometrical primitives such
as points, lines, curves, and
shapes or polygon(s), which
are all based on
mathematical expressions,
to represent images in
computer graphics
typical primitive objects:
lines, polylines and
polygons; bézier curves and
bezigons; circles and
ellipses; text; color gradients
this project is intended to help you understand how to
use the program Adobe Illustrator. This is a vector
based program and does not use bitmaps (things like
erasing or painting are not the same in vectors).

An Article about Adobe Illustrator:
Adobe Illustrator is a vector graphics editor developed and marketed by Adobe Systems. The latest version,
Illustrator CC, is the seventeenth generation in the product line. Adobe Illustrator was first developed for the Apple
Macintosh in December 1986 (shipping in January 1987) as a commercialization of Adobe's in-house font
development software and PostScript file format. Adobe Illustrator is the companion product of Adobe Photoshop.
Photoshop is primarily geared toward digital photo manipulation and photorealistic styles of computer illustration,
while Illustrator provides results in the typesetting and logo graphic areas of design. Early magazine
advertisements (featured in graphic design trade magazines such as Communication Arts) referred to the product
as "the Adobe Illustrator". Illustrator 88, the product name for version 1.7,[1] was released in 1988 and introduced
many new tools and features.[2] As of 2011, the Adobe Illustrator '88 file format is used in the MATLAB
programming language as an option to save figures.
CS3 included interface updates to the Control Bar, the ability to align individual points, multiple Crop Areas, the
Color Guide panel and the Live Color feature among others. CS3 was released March 27, 2007.

CS4 was released in October 2008. It features a variety of improvements to old tools along with the introduction of
a few brand new tools acquired from FreeHand. The ability to create multiple artboards is one of CS4’s main
additions from FreeHand. The artboards allow you to create multiple versions of a piece of work within a single
document. Other tools include the Blob Brush, which allows multiple overlapping vector brush strokes to easily
merge or join, and a revamped gradient tool allowing for more in-depth color manipulation as well as transparency
in gradients.

CS5 was released in April 2010. Along with a number of enhancements to existing functionality, Illustrator CS5's
new features include a Perspective Grid tool taken from FreeHand, a Bristle Brush (for more natural and painterly
looking strokes) and a comprehensive update to strokes, referred to by Adobe as "Beautiful Strokes". Version
CS6 was the sixteenth generation of Adobe Illustrator. Adobe added many more features and several bug fixes.
CS6 was released on April 23, 2012.

Some vector editors support animation, while others
(e.g. Adobe Flash) are specifically geared towards
producing animated graphics. Generally, vector
graphics are more suitable for animation, though
there are raster-based animation tools as well.

Vector editors are often contrasted with bitmap
editors, and their capabilities complement each
other. Vector editors are often better for page
layout, typography, logos, sharp-edged artistic
illustrations (e.g. cartoons, clip art, complex
geometric
patterns),
technical
illustrations,
diagramming and flowcharting. Bitmap editors are
more suitable for retouching, photo processing,
photorealistic illustrations, collage, and illustrations
drawn by hand with a pen tablet. Recent versions
of bitmap editors such as GIMP and Adobe
Photoshop support vector tools (e.g. editable
paths), and vector editors such as CorelDRAW,
EasyCopy, Adobe Illustrator, Xara Photo & Graphic
Designer, Macromedia FreeHand, Adobe Fireworks,
Inkscape or SK1 are adopting raster effects that
were once limited to bitmap editors (e.g. blurring).

A vector graphics editor is a computer program
that allows users to compose and edit vector
graphics images interactively on a computer
(compare with MetaPost) and save them in one of
many popular vector graphics formats, such as EPS,
PDF, WMF, SVG, or VML.
