4.1.4.10 Graphics

 

· Two good formats are,

  1. GIF - well suited to limited color images - no loss in compression. Use these for line images, technical drawings, etc
  2. JPG - well suited to photographs - image can be highly compressed with minimal distortion. Use these for photographs.

 

· Digital cameras will permit image capture and storage - images in JPG format are best.

 

· Scanners will capture images, but this is a poor alternative as the image sizes are larger and image quality is poorer

  1. - Photographs tend to become grainy when scanned.
  2. - Line drawings become blurred.

 

· Screen captures are also possible, but do these with a lower color resolution on the screen (256 color mode).
