PHP is not limited to creating just HTML output. It can also be
|
|
used to create and manipulate image files in a variety of different
|
|
image formats, including gif, png, jpg, wbmp, and xpm. Even more
|
|
convenient, PHP can output image streams directly to a browser. You
|
|
will need to compile PHP with the GD library of image functions for
|
|
this to work. GD and PHP may also require other libraries, depending
|
|
on which image formats you want to work with.

You can use the image functions in PHP to get the size of
|
|
<acronym>JPEG</acronym>, <acronym>GIF</acronym>,
|
|
<acronym>PNG</acronym>, <acronym>SWF</acronym>,
|
|
<acronym>TIFF</acronym> and <acronym>JPEG2000</acronym> images.

<para>
|
|
With the <link linkend="ref.exif">exif extension</link>, you are able
|
|
to work with information stored in headers of
|
|
<acronym>JPEG</acronym> and <acronym>TIFF</acronym> images. This way you can
|
|
read meta data generated by digital cameras. The exif
|
|
functions do not require the <acronym>GD</acronym> library.

Read the requirements section about how to expand image capabilities
|
|
to read, write and modify images. To read meta data of pictures
|
|
taken by digital cameras you need the above mentioned
|
|
<link linkend="ref.exif">exif extension</link>.
