1: \label{Authoring_Internal_Tags} 2: 3: 4: \begin{itemize} 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 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 13: is there (EX. \$hash\{'1'\}=''TEXT-2''). For locations with values, 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 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.) 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} 40: \end{itemize} 41: \end{itemize}
