homework5.html chunked up with authoring information
1: \label{Authoring_Internal_Tags}
2:
3:
4: \begin{itemize}
5: \item \textbf{labelgroup}\index{labelgroup}: One required, multiple allowed.
6: 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). Also the entry \textbf{numlocations}
18: will be set to the total number of locations that exist. (Note that
19: locations and labels start counting from 1.)
20: \item \textbf{type}\index{type}: the type of labels in this group, either
21: '\textbf{image}' or '\textbf{text}'
22: \item \textbf{location}\index{location}: declares a location on the image
23: that a label should appear at. Possible attributes are:
24:
25: \begin{itemize}
26: \item \textbf{x}\index{x}: The x value of the location in pixels.
27: \item \textbf{y}\index{y}: The y value of the location in pixels.
28: \item \textbf{value}\index{value}: An optional scalar value to associate
29: at this location.
30: \item \textbf{label}\index{label}: Declaration of a label. If this is a
31: \textbf{text} type label, the internal text should be the text of
32: the label (HTML is not currently supported); if this is an \textbf{image}
33: type of label, the internal text must be a LON-CAPA resource specification,
34: and the description filed must be set. Possible attributes are:
35:
36: \begin{itemize}
37: \item \textbf{description}\index{description}: Required field for image
38: labels. It will be used when setting values in the hash.
