Title: Vector Graphics


1
Vector Graphics
  • 2.02 Understand Digital Vector Graphics

2

Vector Graphics
  • Graphics that are based on mathematical formulas
    that define lines, shapes, and curves.
  • Are comprised of paths connected by anchor
    points.
  • Can be 2D or 3D.
  • Edited in draw programs.

4
Uses of Vector Graphics
  • Graphics that will be scaled (or resized)
  • Architectural drawings, CAD programs, flow
    charts.
  • Logos that will be scaled (resized) without loss
    of quality.
  • Illustrations and clip art.
  • Graphics on websites.
  • Small file size allows for quick load times.
  • Fonts and specialized text effects

5
Advantages of Vectors
  • Scalable able to change size easily
  • Resolution Independent - Regardless of how much
    the image is enlarged or reduced, the image
    definition and quality remain the same.
  • Editability - since each vector is made up of
    separate and distinct objects, each can be edited
    independently at any time.
  • Small File Sizes - easily transferred over the
    Internet.

6
Disadvantages of Vectors
  • Lower color quality than raster images.
  • They do not support as many colors.
  • Not good for photographic images.
  • Limited in the type of effects that can be
    applied.
  • Can be time consuming to create.
  • Click to see an example.

Common Vector File Formats
  • AI Adobe Illustrator
  • Native file format for Adobe Illustrator.
  • Industry standard used by developers of vector
    graphics.
  • Used to create, save, and archive original
    artwork.

8
Common Vector File Formats
  • EPS Encapsulated Postscript
  • Developed by Adobe but supported by most
    programs.
  • Graphics developers generally save a copy of the
    AI file in EPS format because it can be opened by
    computers running different operating systems.
  • Most common interchange format for the print
    industry due to its portability.
  • Meta Graphic can contain both raster and vector
    data.
  • Shapes in vector graphics can be filled with
    textures and patterns that are raster graphics.

9
Common Vector File Formats
  • SVG Scalable Vector Graphics
  • Standard format created by W3C.
  • Versatile, all-purpose vector format.
  • Works well with web page design.
  • WMF Windows Metafile
  • Microsoft created format for raster and vector.
  • Common format for windows clipart.
