1.1       bowersj2    1: \label{Authoring_Internal_Tags}
                      2: 
                      3: 
                      4: \begin{itemize}
1.2     ! vandui11    5: \item \textbf{labelgroup}\index{labelgroup}: One is required, but multiple are allowed.
        !             6: This declares a group of locations and labels associated with them. Possible
1.1       bowersj2    7: attributes are:
                      8: 
                      9: \begin{itemize}
                     10: \item \textbf{name}\index{name}: This is the name of the group. A hash
                     11: with this name will be generated holding the mappings for later use
                     12: in the problem. For each location a value will be set for which label
1.2     ! vandui11   13: is there (EX. \$hash\{'1'\}=''TEXT-2''). For locations with values,
1.1       bowersj2   14: the hash will contain 2 items, a location to value mapping (\$hash\{'value\_1'\}=10),
                     15: and a label to value mapping (\$hash\{'labelvalue\_2'\}=10). For all
                     16: image style of labels there will also be a label description to label
1.2     ! vandui11   17: URL mapping (\$hash\{'image\_2'\}=IMG-URL). The entry \textbf{numlocations}
        !            18: will also be set to the total number of locations that exist (Note: locations and labels start counting from one.) 
1.1       bowersj2   19: \item \textbf{type}\index{type}: the type of labels in this group, either
                     20: '\textbf{image}' or '\textbf{text}'
                     21: \item \textbf{location}\index{location}: declares a location on the image
                     22: that a label should appear at. Possible attributes are:
                     23: 
                     24: \begin{itemize}
                     25: \item \textbf{x}\index{x}: The x value of the location in pixels.
                     26: \item \textbf{y}\index{y}: The y value of the location in pixels.
                     27: \item \textbf{value}\index{value}: An optional scalar value to associate
                     28: at this location.
                     29: \item \textbf{label}\index{label}: Declaration of a label. If this is a
                     30: \textbf{text} type label, the internal text should be the text of
                     31: the label (HTML is not currently supported); if this is an \textbf{image}
                     32: type of label, the internal text must be a LON-CAPA resource specification,
                     33: and the description filed must be set. Possible attributes are:
                     34: 
                     35: \begin{itemize}
                     36: \item \textbf{description}\index{description}: Required field for image
                     37: labels. It will be used when setting values in the hash.
                     38: \end{itemize}
                     39: \end{itemize}
