VECTOR GRAPHICSBrief discussion about vector graphics
-
Vector Graphicsa method of generating images that uses mathematical descriptions to determine the position, length, and direction in which lines are to be drawn.
-
Vector Graphicsan alternative to raster graphics
-
THE ANATOMY OF ILLUSTRATION
-
An ILLUSTRATION is composed of different vector OBJECTSIllustration:Objects:
-
Each OBJECT have one or more PATHSPaths:
-
PATHS are composed of LINE SEGMENTS that usually have ANCHOR POINTS at each endLine Segments and Anchor Points:
-
Anchor Points are the fundamental components of any vector image define the position and curve properties of a line segment
Bezier Curve
-
Anchor Points may or may not have CONTROL HANDLES Each Point has one or two Control Handles
-
ObjectsStroke can be applied to the PATH of an object Fill can be applied to the area enclosed by the PATH
-
Stroke may have properties such as weight, color, Solid vs. Dashed, Line Caps or CornersFill may have properties such as Color, Uniform or Gradient, Pattern or Texture

Common Vector FormatsSWF (Shockwave Flash)SVG (Scalable Vector Graphics)AI (Adobe Illustrator) CDR (CorelDRAW) CMX (Corel Exchange) CGM Computer Graphics Metafile DXF AutoCAD WMF Windows Metafile

WHEN TO USE VECTOR GRAPHICS?
-
Resolution IndependentYou can increase and decrease the size of vector images to any degree and your lines will remain crisp and sharp.
-
RasterizinggnizirotceVVector images can be easily converted into raster images but not vice versa.
-
No background Vector objects can be placed over other objects, and the object below will show through. Vector Raster
-
DISADVANTAGES OF VECTOR GRAPHICS
-
Cartoonish PropertyThey're unsuitable for producing photo-realistic imagery.
-
TRNOnce converted to Bitmap format, it loses all its features.
