If you have the <acronym>GD</acronym> library (available at <link
|
|
xlink:href="&url.gd;">&url.gd;</link>) you will also be able to create
|
|
and manipulate images.
|

</para>
|
|
<para>
|
|
The format of images you are able to manipulate depend on the
|
|
version of <acronym>GD</acronym> you install, and any other libraries
|
|
<acronym>GD</acronym> might need to access those image formats.
|
|
<note>
|
|
<simpara>
|
|
libgd-2.1.0 or higher is required. Alternatively, use
|
|
the bundled <acronym>GD</acronym> library that ships with PHP.

When building the jpeg library (prior to building PHP) you
|
|
must use the <option role="configure">--enable-shared</option>
|
|
option in the configure step. If you do not, you will receive
|
|
an error saying <literal>libjpeg.(a|so) not found</literal>
|
|
when you get to the configure step of building PHP.
