(c) Marcus Boerger, 2002
Images taken from www.exif.org,
marcus-boerger.de
all rights reserved by their authors and artists, see exif headers.
The files can be downloaded here.
To start the test you simple have to put all images into the same directory as this script.
The test will work with all files in that directory and all subdirectories. To test private
images just put them into that directory.
Youmay take a look at the test source here.
This test just prooves that some exif headers can be scanned.
If all files produce a header in output the module might be o.k.
What to look for in detail:
- kodak-dc4800-plus-acdsee.jpg
- should provide a long comment 'by marcus börger<%04i>'*n
- this file returns an array but it also produces an errormessage because ACDSee destroys
the integrity of IFD directory (size of directory and offsets of entries following any
edited entry maybe wrong).
- hp-photosmart.jpg
- should provide a two line copyright notice
- olympus-d320l
- should provide an APP12 infoset
- unknown.jpg
- should provide an empty comment, this is a comment section and not an IFD0, EXIF or GPS section
- some images
- have empty fields, that is the tag is present but no data is stored
