After finishing the movie, work on the image mapping. First we have to choose
where each image or the series of images should lead a user. A list of
images should be made first, note the beginning and ending of the points using a
running time displayed at the bottom of a RealPlayer. Then write the map file, which
is simply the text file. Here is a part of the code for my image map which must give
a good idea of the information we need to create on own:
The first things we probably notice here is that a map begins with a duration
of video. The time has been marked with days:hours:minutes:seconds:milliseconds.
We should note each of these time specs, and if any one of the measurement is empty,
be sure to stick to the zero or a map will not work.
Notice that a map is divided into the areas. An area is defined by a starting time and the
ending time within a video's time line. We used the areas to indicate the image or
series of images that are been connected to the unique URL. It is also possible to define
a different shapes within the area. The space within a shape is a hot spot which will
take us to the URL (as a regular image map). The shape is defined by the coordinates,
which we believe are in pixel width - although we cannot verify this, since
a documentation on a RealPlayer site was vague.
