      –   Select a range of images and view them as a slideshow
      –   Can take a long time to load
      –   Many images in library may not be required/similar
Resources for Teaching Ltd                                                   www.ocrict.org

  Describe the differences between vector and bitmap
  graphics

  • Difference between vector and bitmap graphics
      – Vector
          • Information about image held as geometric data, e.g, start point, end point,
            thickness of line and colour
          • Device dependent
          • Allows images to be stretched and reduced with no loss
          • Low memory / high processor requirements
      – Bitmap (known as pixel based)
          •   Image stored as pixels (square of colour)
          •   More pixels = higher quality
          •   By altering colour of each pixel causes changes in the image
          •   Based on display adapter
          •   Blurring (pixelation) caused by stretching/enlarging image         a 4 x 3 pixel image
                                                                                  = 12 pixels total
          •   High memory requirements
Resources for Teaching Ltd                                               www.ocrict.org


  Evaluate their suitability for given applications
  • Vector
      – Used for CAD programs
      – Used for maps – individual lines and layers
      – Building design / architectural drawings


  • Suitability
      – Allows resizing without pixelation / Scalability of image
      – File size based on complexity rather than size or colour depth
      – Components can be individually manipulated rather than whole image
      – Can create layers and edit individual layers
Resources for Teaching Ltd                                            www.ocrict.org


  Evaluate their suitability for given applications
  • Bitmap
      – Bitmapped used in web based images
      – Photos and scanned images


  • Suitability
          • What you see is what you get
              – usually in real time - similar to when using a “paintbrush”
          • Much easier to create the appearance of “natural” media and real life
            images
          • More universally available interchange file formats
               – most bitmaps can be read by most bitmap-based software and
                 certain file formats such as jpeg and png can be read and written by
                 every “painting” program.
          • Fine control over individual pixels
Resources for Teaching Ltd                                              www.ocrict.org

  Describe the advantages and disadvantages of using
  graphic libraries

  • Graphic libraries are collections of images all related to the
    same topic.
  • They are accessible through specific programs
  • Advantages
      – The final result will contain the proper symbols and look like the finished
        article.
      – If the known symbols are used then more people will recognise and
        understand the picture.
      – The images required will all be stored in one place
      – Specific add on packages can be released
      – Companies can release graphic libraries for their specific products
Resources for Teaching Ltd                                           www.ocrict.org

  Describe the use of graphic libraries in: kitchen design,
  cartography and network design

  • Collections of images relating to specific items network
    components, database diagram boxes
      – These can be used when creating network diagrams – include images of
        switches, computers and printers
  • In kitchen design, companies can supply graphic
    images of their sinks, cupboards and appliances
      – The end user can get a very good idea of what the kitchen
         will look like
  • Cartography (map making) – there are set symbols used in
    map making
      – A graphic library can present these and allow the end user
         to select which one they want

  Describe the features of presentation software: sound,
  video, slide transition and hyperlinks/hotspots

   Sound                            To announce a page
                                    Sound for company/signature tune/description of product
                                    Confirmation of action/error
   Hyperlinks                       For navigation
   Hotspots                         To go to other company products
                                    Hotspot is a part of an image that has a hyperlink
                                    attached to it. Several different hyperlinks can be
                                    created on the same image.
   Video                            To demonstrate a product.
                                    To clarify the ordering/web site use process
                                    To make site more interesting/user friendly
                                    Corporate video to increase corporate/brand recognition
   Slide Transition                 Can be the same to stop the customer losing focus
                                    Or different to try and maintain their interest
                                    The age group will determine how much and the type of
                                    transition

  Compare delivering a presentation using printed acetate
  and using a computer and projector

                     OHT                                  Slideshow
    Fingerprints on slides                  Good quality
    Non linear order – can go backwards,    Linear progression – can go back but
    forwards and out of order               untidy
    Can skip slides                         Audience will see navigation
    Manually controlled                     Can be automatic
    Less equipment required - OHP           Requires laptop and projector - lots of
                                            equipment – risk of some not working
    Less risk of equipment not working      Can be interactive,
    Static presenter – needs to be at front Can move around the room and run
                                            by remote control
    Static presentation                     Sound, animation and movies
                                            included
    Less common so OHP may not be           Updated immediately (e.g. if spelling
    available                               error found)

  Compare and give advantages and disadvantages of
  different modes of navigation

  • Automatic Transition
      –   After a period of time the slide automatically moves to the next
      –   Equipment can be out of reach – less chance of vandalism
      –   Can be used as a background presentation – set and leave
      –   If giving presentation cannot have interruptions as timings will go wrong
  • Manual Transition
      – Click the mouse/hyperlink/hotspot to move to a next slide
      – Need user input to view the presentation
      – Can take as much time as you want on each slide



  • Advantages of manual are the disadvantages of automatic and vice
    versa. Both are completed on the computer.
Resources for Teaching Ltd                            www.ocrict.org

  Identify and give examples of when the use of each
  method is more suitable

  • Automatic
      – Kiosk application
      – Background application
      – Where a set presentation is given each time
         • Aircraft safety
  • Manual
      – Giving a presentation
      – Speaking to a set of slides
      – Questions from an audience
Resources for Teaching Ltd                       www.ocrict.org


  Describe nonlinear and hierarchical presentations

  • Hierarchical
      – Where one slide leads to another
      – Can go forwards or backwards
      – Linear sequence
  • Non-Linear
      – Any slide can go to any other
      – No specific pathway through the slides
      – Choice down to user no designer
Resources for Teaching Ltd                                            www.ocrict.org


  Give the advantages and disadvantages of each

  • Hierarchical
      – Pathway through the presentation is predictable
      – Handouts given to delegates can match the slideshow
      – If necessary, presentation can be completely linear with no choice
      – Can be automated
      – Simple to use and create
  • Non-Linear
      – Same presentation can be used in different situations
      – User decides the path through the presentation
      – Can be complicated to create
      – End user might not see all the slides
      – Some slides might have no path to them
Resources for Teaching Ltd                                         www.ocrict.org

  Identify and give examples of where each may be more
  suitable

  • Hierarchical
      – Automated presentation
      – Kiosk application
      – Presentation given by speaker
  • Non-Linear
      – User follows presentation on their own
      – Decision making presentations
      – Expert system clones
      – Could be used in classroom presentation
         • different slides shown when wrong and right answers are selected
         • extra explanation slides could be shown if a class needs them
