1. Bitmap vs. Vector

2. Bitmap Images Bitmap Images are also know as Raster Images
Image consists of a matrix of individual dots (or pixels)
All pixels have their own color

3. Bitmap Images As you get closer images becomes more pixilated
Resolution and image size determines file size for bitmap images.

4. Bitmap Images
Resolution describes the number of Pixels Per Inch (PPI) and is measured width x height
Computer Screens usually display around 72 PPI
Professional prints are usually done at 300 PPI

5. Bitmap Images Some Common Bitmap File types
BMP Bitmap (Windows format that is simple and uncompressed…usually larger format)
GIF (Generally used for animation because it only supports 256 colors)
JPG (Compression file that loses quality with each save)

6. Vector Images Advantages
Images that are completely described using mathematical definitions
Generally smaller size files

7. Vector Images
Individual line is made up of either a vast collection of points with lines interconnecting all of them or just a few control points that are connected using Bezier Curves

8. Vector Images Advantages
Preferred in logo creation because they are easily editable from design to color to effects
Easily converted to Bitmap files

9. Vector Images Disadvantages Cannot be imported from outside source
More difficult to get lifelike designs

10. Vector Images Some Common File Types EPS Encapsulated PostScript
