14 The PHP Exif Library (PEL) makes it easy to develop programs that will
15 read and write the Exif metadata headers found in JPEG and TIFF
16 images. See the file INSTALL for an introduction to how PEL can be
17 used by your application.
19 PEL is a library written entirely in PHP 5, which means that it does
20 not have any dependencies outside the core of PHP, it does not even
21 use the Exif module available for PHP.
23 Please note that the API for PEL is not yet frozen, and it will remain
24 changeable until version 1.0 is reached. Read the NEWS file for
25 important information about API changes.
27 Also, please go to the PEL development mailing list (look below) and
28 share your ideas about how the API should look like.

53 Help will be very much appreciated. You can report issues, run the test
54 suite, add patches. The best way to help out is applying patches and
55 helping out with the tests. See instructions in the test/ directory.
57 All changes to code should be issued through a pull request, and other
58 maintainers should review the code and merge it.
63 To work with the translations, you need the gettext package installed.
68 The first place you should consult for support is the documentation
69 supplied with PEL, found in the doc/ directory. There you will find a
70 complete API documentation with descriptions of all classes and files
73 The scripts found in the examples/ directory are also a good source of
74 information, especially the edit-description.php file which has tons
77 PEL is hosted on Github and uses the tools found there for
78 support. This means that all questions, bug reports, etc. should be
79 directed there (and not directly to the developers).
81 Please try the latest version before reporting bugs -- it might have
82 been fixed already. The latest code can be found in the git
85 http://github.com/lsolesen/pel
87 It is very helpful if you try out the latest code from the git
88 repository before submitting a bug report. The code found there is
89 generally very stable.
92 ## Contributing Test Images
94 To make PEL as stable as possible, it is tested with images from a
95 number of different camera models.
97 New test images are very much appreciated -- please download the
98 existing test images and read the README file found there for
