\label{Authoring_Internal_Tags} \begin{itemize} \item \textbf{labelgroup}\index{labelgroup}: One required, multiple allowed. Declares a group of locations and labels associated with them. Possible attributes are: \begin{itemize} \item \textbf{name}\index{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). Also the entry \textbf{numlocations} will be set to the total number of locations that exist. (Note that locations and labels start counting from 1.) \item \textbf{type}\index{type}: the type of labels in this group, either '\textbf{image}' or '\textbf{text}' \item \textbf{location}\index{location}: declares a location on the image that a label should appear at. Possible attributes are: \begin{itemize} \item \textbf{x}\index{x}: The x value of the location in pixels. \item \textbf{y}\index{y}: The y value of the location in pixels. \item \textbf{value}\index{value}: An optional scalar value to associate at this location. \item \textbf{label}\index{label}: Declaration of a label. If this is a \textbf{text} type label, the internal text should be the text of the label (HTML is not currently supported); if this is an \textbf{image} type of label, the internal text must be a LON-CAPA resource specification, and the description filed must be set. Possible attributes are: \begin{itemize} \item \textbf{description}\index{description}: Required field for image labels. It will be used when setting values in the hash. \end{itemize} \end{itemize} \end{itemize} \end{itemize}
