3/* Test script for PHP module ext/exif
4 *
5 * (c) Marcus Boerger, 2002
6 *
7 * $Id$
8 *
9 * Rename the file to test.php and read the instructions. If the
10 * script cannot be executed or does not generate any output check
11 * you error log. In most cases this would mean you found an error
12 * if the rest of your php environment works fine.
13 *
14 * The original version of module exif has many errors and mostly
15 * fails on executing this script.

183Images taken from <a href="http://www.exif.org">www.exif.org</a>,
184<a href="http://marcus-boerger.de">marcus-boerger.de</a>
185all rights reserved by their authors and artists, see exif headers.
186The files can be downloaded <a href="http://marcus-boerger.de/php/ext/exif/test/">here</a>.
187To start the test you simple have to put all images into the same directory as this script.
188The test will work with all files in that directory and all subdirectories. To test private
189images just put them into that directory.
190</p>
191<p>
192Youmay take a look at the test <a href="http://marcus-boerger.de/php/ext/exif/test.txt">source here</a>.
193</p>
194<p>
195This test just prooves that some exif headers can be scanned.
196If all files produce a header in output the module might be o.k.
197</p>
198<p>
199What to look for in detail:
200</p>
201<ul>
202<li>kodak-dc4800-plus-acdsee.jpg
203	<ul>
204	<li>should provide a <b>long</b> comment 'by marcus b&ouml;rger&lt;%04i&gt;'*n</li>
205	<li>this file returns an array but it also produces an errormessage because ACDSee destroys
206	    the integrity of IFD directory (size of directory and offsets of entries following any
207	    edited entry maybe wrong).
208	</li>
209	</ul>
210</li>
211<li>hp-photosmart.jpg
212	<ul>

216<li>olympus-d320l

220</li>
221<li>unknown.jpg
222	<ul>
223	<li>should provide an <b>empty</b> comment, this is a comment section and not an IFD0, EXIF or GPS section</li>
224	</ul>
225</li>
226<li>some images
227	<ul>
