<para>
<function>imagejpeg</function> creates the
<acronym>JPEG</acronym> file in filename from the image
<parameter>image</parameter>. The <parameter>image</parameter> argument
is the return from the <function>imagecreate</function> function.
</para>
<para>
The filename argument is optional, and if left off, the raw image
stream will be output directly. To skip the filename argument in
order to provide a quality argument just use an empty string
(''). By sending an image/jpeg content-type using
<function>header</function>, you can create a PHP script that
outputs JPEG images directly.
</para>
¬e.config.jpeg;
<para>
<parameter>quality</parameter> is optional, and ranges from
0 (worst quality, smaller file) to 100 (best quality, biggest file).
The default is the default IJG quality value (about 75).
</para>
<para>
If you want to output Progressive JPEGs, you need to set interlacing
on with <function>imageinterlace</function>.
