<h1>Image</h1>
<code>Image(<b>string</b> file [, <b>float</b> x [, <b>float</b> y [, <b>float</b> w [, <b>float</b> h [, <b>string</b> type [, <b>mixed</b> link]]]]]])</code>
<h2>Description</h2>
Puts an image. The size it will take on the page can be specified in different ways:
<ul>
<li>explicit width and height (expressed in user unit)</li>
<li>one explicit dimension, the other being calculated automatically in order to keep the original proportions</li>
<li>no explicit dimension, in which case the image is put at 72 dpi</li>
</ul>
Supported formats are JPEG, PNG and GIF. The GD extension is required for GIF.
<br>
<br>
For JPEGs, all flavors are allowed:
<ul>
<li>gray scales</li>
<li>true colors (24 bits)</li>
<li>CMYK (32 bits)</li>
</ul>
For PNGs, are allowed:
<ul>
<li>gray scales on at most 8 bits (256 levels)</li>
<li>indexed colors</li>
<li>true colors (24 bits)</li>
</ul>
but are not supported:
<ul>
<li>Interlacing</li>
<li>Alpha channel</li>
</ul>
For GIFs: in case of an animated GIF, only the first frame is used.<br>
<br>
If a transparent color is defined, it is taken into account.<br>
<br>
The format can be specified explicitly or inferred from the file extension.<br>
It is possible to put a link on the image.<br>
<br>
Remark: if an image is used several times, only one copy is embedded in the file.
<h2>Parameters</h2>
<dl class="param">
<dt><code>file</code></dt>
<dd>
Path or URL of the image.
</dd>
<dt><code>x</code></dt>
<dd>
Abscissa of the upper-left corner. If not specified or equal to <code>null</code>, the current abscissa
is used.
</dd>
<dt><code>y</code></dt>
<dd>
Ordinate of the upper-left corner. If not specified or equal to <code>null</code>, the current ordinate
is used; moreover, a page break is triggered first if necessary (in case automatic page breaking is enabled)
and, after the call, the current ordinate is moved to the bottom of the image.
</dd>
<dt><code>w</code></dt>
<dd>
Width of the image in the page. If not specified or equal to zero, it is automatically calculated.
</dd>
<dt><code>h</code></dt>
<dd>
Height of the image in the page. If not specified or equal to zero, it is automatically calculated.
</dd>
<dt><code>type</code></dt>
<dd>
