Vector graphics use mathematical descriptions to determine the position, length, and direction of lines in an image. An illustration in vector graphics is composed of objects, which contain paths made of line segments and anchor points. Anchor points define the position and curve of line segments and may have control handles. Objects can have properties like strokes (weight, color, style) and fills (color, pattern, texture). Common vector formats include SVG, AI, CDR, and DXF. Vector graphics are resolution independent and objects can be placed over each other with transparency, but they are not suitable for realistic imagery and lose features if converted to raster.

2. VECTOR GRAPHICS Brief discussion about vector graphics

3. Vector Graphics a method of generating images that uses mathematical descriptions to determine the position, length, and direction in which lines are to be drawn.

4. Vector Graphics an alternative to raster graphics

5. THE ANATOMY OF ILLUSTRATION

6. An ILLUSTRATION is composed of different vector OBJECTS Illustration: Objects:

7. Each OBJECT have one or more PATHS Paths:

8. PATHS are composed of LINE SEGMENTS that usually have ANCHOR POINTS at each end Line Segments and Anchor Points:

9. Anchor Points … are the fundamental components of any vector image … define the position and curve properties of a line segment Bezier Curve

10. Anchor Points may or may not have CONTROL HANDLES Each Point has one or two Control Handles

11. Objects Stroke can be applied to the PATH of an object Fill can be applied to the area enclosed by the PATH

12. Stroke may have properties such as weight, color, Solid vs. Dashed, Line Caps or Corners Fill may have properties such as Color, Uniform or Gradient, Pattern or Texture

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

14. Stroke Examples: Fill Examples: Solid Dashed None Pattern* Linear Gradient Radial Gradient Pattern Texture*

17. Raster Image Vector Image

18. WHEN TO USE VECTOR GRAPHICS?

19. R e so lut io n I nde pe n den t You can increase and decrease the size of vector images to any degree and your lines will remain crisp and sharp.

20. Rasterizing gnizirotceV Vector images can be easily converted into raster images but not vice versa.

21. No background Vector objects can be placed over other objects, and the object below will show through. Vector Raster

22. DISADVANTAGES OF VECTOR GRAPHICS

23. Cartoonish Property They're unsuitable for producing photo-realistic imagery.

24. TRN Once converted to Bitmap format, it loses all its features.
