Metadata Exif Version 0.9.0 (currently a WIP) for PW 2.8.+ / 3.0+ This is a new attempt to add easy EXIF reading support to ProcessWire. It should be an easy and less error prone API task. Thats why the module internally uses lowercase key names for all EXIF keys and all of your requested key names. But you are not forced to use lowercase key names, you can use any mixed chars for it as you like. You will get back an array or object with keynames / properties named the same (casesensitive) way as you have passed them in with your request. API The module adds one hook to the Pageimage: getExif($options = null) Without any $options passed to the method, it returns all EXIF data in a RAW multidim array. Passing a simple list with requested key names as array to it returns an array with only the values of those requested keynames. If you want change the output from array to object, you can use the a boolean "toObject" set to true. Additionally to this and / or any other option, you need to put your requested keynames list to the option "keys". $rawArray = $image->getExif(); $options = array('Whitebalance', 'Flash', 'ISOSpeedRatings', 'FNumber', 'UserComment'); $array = $image->getExif($options); $options = array('toObject' => true, 'keys' => array('whitebalance', 'flash', 'isospeedratings', 'fnumber', 'usercomment')); $object = $image->getExif($options); Possible options are A working example $options = array( 'keys' => array('ISOSpeedRatings', 'FNumber', 'Flash') ); echo "<table><tr>"; foreach($options['keys'] as $key) echo "<th>{$key}</th>"; echo "</tr>"; foreach($page->images as $image) { $exif = $image->getExif($options); echo "<tr>"; foreach($exif as $value) echo "<td>$value</td>"; echo "</tr>"; } echo "</table>"; This will output something like: With the boolean option "unformatted" passed as true, the output would look like: For some keys, that only store something like integer values, what are not very meaningful to most of us, the module contain xyzFormatted methods. This way, it is easy to enhance and maintain the module in the future. Help wanted It would be nice if some of you test the module and report back if the intended API suites your needs. And you are very welcome to post suggestions for which keys you want to have a ...Formatted method. Thank you! https://github.com/horst-n/MetadataExif

Hhm, I don't want use the GD2-lib at some point because it lacks in quality. Also I want to add Metadata (IPTC, XMP, ...) back to resized images. (It's just curious, I'm not aware of any CMS, Blog or even webdriven Photogallery that takes care of this!) I need to know a way how to bypass PW-internal image-sizing. This must not be necessary for a complete PW-site, but possibly could. It is mandatory for images added to a specific Part (Template? / Gallery?) of the site. I want to: - read Metadata - resize image with alternate ImageProcessor - write back Metadata Any ideas or starting points for this? To be more clear: I know how to do the image-processing, but not how to integrate the alternate process into PW.
