<p>Image maps makes it possible to create images with "active" areas that will react for
|
|||
|
|
a mouse-click. It is then up to the designer to decide what actions should be taken.
|
|||
|
|
Image map is often used to create drill-down charts where it is possible to dynamically
|
|||
|
|
zoom into an image. Image maps is part of the HTML standard.</p>
|
|||
|
|
<p>There are actually two types of images maps, client and server-side. This refers to
|
|||
|
|
where the actual processing of the image click happens. Without doubt the best (and most
|
|||
|
|
commonly used) type is the client side. This is also what the library supports. In the
|
|||
|
|
remainder of this manual this will be referred to as <span class="bold"><strong>CSIM</strong></span>, <span class="bold"><strong>C</strong></span>lient <span class="bold"><strong>S</strong></span>ide <span class="bold"><strong>I</strong></span>mage <span class="bold"><strong>M</strong></span>aps.</p>

<p>Image maps works so that each hotspot area in the graph that should be used must
|
|||
|
|
have an associated URL. When the user clicks somewhere in that particular hotspot
|
|||
|
|
area the browser will open the specified URL. Typical hotspot areas in the graphs
|
|||
|
|
are</p>

<p>The way the CSIM HTML standard works is that the HTML page must have a section
|
|||
|
|
with coordinates that defines the various hotspots together with the associated URL
|
|||
|
|
that should be called. Each section of coordinates are connected to a specific image
|
|||
|
|
that is included with a standard <span class="markup"><img></span> by a common id. This will
|
|||
|
|
now add some complexity since the library must return an HTML page for the
|
|||
|
|
coordinates and not image data as normal for the library. How this is done is the
|
|||
|
|
topic of the next section.</p>
|
|||
|
|
<p>A number of examples of CSIM graphs are included in the
|
|||
|
|
<code class="filename">Examples/</code> directory. Some of the available examples are
|
|||
|
|
listed in <a class="xref" href="ch10.html#tab.csim-examples-name" title="Table 10.1. CSIM Examples (in Examples/ directory)">Table 10.1. CSIM Examples (in Examples/ directory)</a></p>

<p>In order to easily access all of these examples it is possible to call the

<code class="filename">testsuit.php</code> example with an additional argument

"<code class="code">t=2</code>". By following the link
