### Vector And Illustrator 03

1. 2. VECTOR GRAPHICS <ul><li>Brief discussion about vector graphics </li></ul>
2. 3. Vector Graphics <ul><li>a method of generating images that uses mathematical descriptions to determine the position, length, and direction in which lines are to be drawn. </li></ul>
3. 4. Vector Graphics <ul><li>an alternative to raster graphics </li></ul>
4. 5. THE ANATOMY OF ILLUSTRATION
5. 6. <ul><li>An ILLUSTRATION is composed of different vector OBJECTS </li></ul>Illustration: Objects:
6. 7. <ul><li>Each OBJECT have one or more PATHS </li></ul>Paths:
7. 8. <ul><li>PATHS are composed of LINE SEGMENTS that usually have ANCHOR POINTS at each end </li></ul>Line Segments and Anchor Points:
8. 9. Anchor Points <ul><li>… are the fundamental components of any vector image </li></ul><ul><li>… define the position and curve properties of a line segment </li></ul>Bezier Curve
9. 10. <ul><li>Anchor Points may or may not have CONTROL HANDLES </li></ul><ul><li>Each Point has one or two Control Handles </li></ul>
10. 11. Objects <ul><li>Stroke can be applied to the PATH of an object </li></ul><ul><li>Fill can be applied to the area enclosed by the PATH </li></ul>
11. 12. <ul><li>Stroke may have properties such as weight, color, Solid vs. Dashed, Line Caps or Corners </li></ul><ul><li>Fill may have properties such as Color, Uniform or Gradient, Pattern or Texture </li></ul>
12. 13. Common Vector Formats <ul><li>SWF (Shockwave Flash) </li></ul><ul><li>SVG (Scalable Vector Graphics) </li></ul><ul><li>AI (Adobe Illustrator) </li></ul><ul><li>CDR (CorelDRAW) </li></ul><ul><li>CMX (Corel Exchange) </li></ul><ul><li>CGM Computer Graphics Metafile </li></ul><ul><li>DXF AutoCAD </li></ul><ul><li>WMF Windows Metafile </li></ul>
14. 15. Path and Subpaths <ul><li>Open or Closed </li></ul>Open Closed
15. 16. RASTER VS. VECTOR <ul><li>Comparison on the two types of images </li></ul>
16. 17. <ul><li>Raster Image </li></ul><ul><li>Vector Image </li></ul>
17. 18. WHEN TO USE VECTOR GRAPHICS?
18. 19. R e so lut io n I nde pe n den t <ul><li>You can increase and decrease the size of vector images to any degree and your lines will remain crisp and sharp. </li></ul>
19. 20. Rasterizing gnizirotceV <ul><li>Vector images can be easily converted into raster images but not vice versa. </li></ul>
20. 21. No background <ul><li>Vector objects can be placed over other objects, and the object below will show through. </li></ul>Vector Raster
21. 22. DISADVANTAGES OF VECTOR GRAPHICS
22. 23. Cartoonish Property <ul><li>They're unsuitable for producing photo-realistic imagery. </li></ul>
23. 24. TRN <ul><li>Once converted to Bitmap format, it loses all its features. </li></ul>
