  • 3) Data source and standard document links and merged.
  • 4) Personalised document printed/sent

Disadvantages & Advantages of Mail Merge:

  • Documents can be produced quickly.
  • Only one copy needs to be proofread to ensure that all are correct.
  • Data source can be used for many different mail merges.
  • Standard template can be reused.
  • Letter can sound generic.
  • Can be used to create vast amount of junk mail

Chapter 6 - Vector & Bitmap Graphics

Bitmap Graphics - Are made up of pixels, each with a position on the image grid and a colour value.

  • Stored as pixels.
  • Quality is reduced when resizing
  • Each pixel is saved individually > larger file size than vector graphics
  • Screen resolution can affect the image quality.
  • Can be compressed
  • Can deal well with highly detailed images (e.g. photographs)

.

  • Bitmap graphics are produced when a scnaner or camera is used.
  • Can be saved in different formats - BMP, GIF, JPEG and TIFF

Chapter 6 - Vector & Bitmap Graphics

Vector Graphics - Contain mathematical data that defines the key properties of every element in the graphic.

  • Can be resized with no loss of definition.
  • Smaller file size than bitmap graphics.
  • Can't be compressed.
  • High processing power to display.
  • Can't be grouped.

 - Used for design purposes and in CAD programs. It's used by architects and designers, where it allows users to change sizes, perspectives and proportions of components in their drawings.

Chapter 6 - Graphics Libraries

Advantages and Disadvantages of Graphics Libraries:

  • Industry-standard symbols are available.
  • Symbols will be internationally recognised.
  • Images required will all be stored in one place.
  • May be difficult to keep up to date.
  • New components may not be immediately available.
  • Componenets may be added that aren't used or available.

Applications:

  • Kitchen Design: include standard symbols for cupboards and kitchen appliances
  • Cartography: include symbols used by the Ordnance Survey so maps created for specific purposed will use the symbols on standard maps
  • Network Design: include industry-standard symbols for the main components in a network e.g. servers, routers and cabling
