<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 or dpi)</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 96 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>
|
||
|
|
For GIFs: in case of an animated GIF, only the first frame is displayed.<br>
|
||
|
|
<br>
|
||
|
|
Transparency is supported.<br>
|
||
|
|
<br>
|
||
|
|
The format can be specified explicitly or inferred from the file extension.<br>
|
||
|
|
<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.

|
||
|
|
<dt><code>x</code></dt>
|
||
|
|
<dd>
|
||
|
|
Abscissa of the upper-left corner. If not specified or equal to <code>null</code>, the current abscissa
