LON-CAPA Help

• labelgroup: One is required, but multiple are allowed. This declares a group of locations and labels associated with them. Possible attributes are:
  • name: This is the name of the group. A hash with this name will be generated holding the mappings for later use in the problem. For each location a value will be set for which label is there (EX. $hash{'1'}="TEXT-2"). For locations with values, the hash will contain 2 items, a location to value mapping ($hash{'value_1'}=10), and a label to value mapping ($hash{'labelvalue_2'}=10). For all image style of labels there will also be a label description to label URL mapping ($hash{'image_2'}=IMG-URL). The entry numlocations will also be set to the total number of locations that exist (Note: locations and labels start counting from one.)

  • type: the type of labels in this group, either 'image' or 'text'

  • location: declares a location on the image that a label should appear at. Possible attributes are:
    • x: The x value of the location in pixels.

    • y: The y value of the location in pixels.

    • value: An optional scalar value to associate at this location.

    • label: Declaration of a label. If this is a text type label, the internal text should be the text of the label (HTML is not currently supported); if this is an image type of label, the internal text must be a LON-CAPA resource specification, and the description filed must be set. Possible attributes are:
      • description: Required field for image labels. It will be used when setting values in the hash.
