Two basic marking methods are possible:

Mark per OptionThe question is marked out of the number of placeholders.
Mark per QuestionAll placeholders have to be correctly answered for the mark

In either marking method academic staff should be able to specify the number of marks to award if correct and the number (possibly negative) if wrong. Marks correct should range from 1 to 20 and marks incorrect from 0 to -10 with the addition of -0.25 and -0.5.

  1. First split by a semicolon.
  2. Element 0 = Label line colour (Flash-style hexadecimal values)
  3. Element 1 = Width of line in pixels
  4. Element 2 = Label background fill colour
  5. Element 3 = Label font size
  6. Element 4 = Label font colour
  7. Element 5 = Label width in pixels (text)
  8. Element 6 = Label height in pixels (text)
  9. Element 7 = Label width in pixels (images)
  10. Element 8 = Label height in pixels (images)
  11. Element 9 = Mode: 1) single - each label is used once, 2) multiple - each label can used in an answer repeatedly.
  12. Element 10 = Style (label or menu)
  13. Element 11 - split by | character
    1. Split by $ character
      1. 0 = Label ID starting at zero.
      2. 1 = Instance of the label starting at zero (this is incremented by one when in repeating label mode)
      3. 2 = X coordinate of left of label (this coordinate being greater than 219 marks it as being a correct answer)
      4. 3 = Y coordinate of top of label
      5. 4 = Text (or image filename) of the label
      6. 5 = Option when using images - original width of image in pixels
      7. 6 = Option when using images - original height of image in pixels
    2. Element 12 (onward) - split by $ character:
      1. 0 = ID of additional line
      2. 1 = Type (line, bobble or arrow)
      3. 2 = Start x coordinate
      4. 3 = Start y coordinate
      5. 4 = End x coordinate
      6. 5 = End y coordinate
