writing exif data does not work

[hostingnuggets]

I am trying to add a copyright notice to photos using your package but unfortunately it does not seem to work, when running the "exif" command on the processed image file I get:

Corrupt data
The data provided does not follow the specification.
ExifLoader: The data supplied does not seem to contain EXIF data.

If I open the JPG image in GIMP it doesn't show many anything under the copyright tab of the image properties.

I use the following code which is pretty much the same as in your README:

            $logger = new Logger('exiftool');
            $Writer = Writer::create($logger);
            $bag = new MetadataBag();
            $bag->add(new Metadata(new CopyrightNotice(), new Mono('Test copyright notice')));
            $Writer->write($filteredFilename, $bag);

and use v0.3 of the package. Any ideas?

please provide a namespaced snippet.
Can you provide the output of the logs ?

[hostingnuggets]

here would be the relevant namespace:

use Monolog\Logger;
use PHPExiftool\Writer;
use PHPExiftool\Driver\Metadata\Metadata;
use PHPExiftool\Driver\Metadata\MetadataBag;
use PHPExiftool\Driver\Tag\IPTC\CopyrightNotice;
use PHPExiftool\Driver\Value\Mono;

but I can't find any output regarding this pacakge in my log file, I am using symfony 2.5.0 and the app/logs/dev.log file does not contain anything about phpexiftool. or is there another log I am missing?

I have problems with Writing as well, used the example in readme file, same as hostingnuggets posted in his post.

I get a white screen of death, no error in any logs what I can find.

Read EXIF data works just fine, but then trying to create the Write object ($Writer = Writer::create();) the return will be white page of death.

Hello guys,

Please provide complete snippets of code, I can't do anything with pieces that I should assemble myself.

Here is the code im trying to run:

  require __DIR__ . '/vendor/autoload.php';

  use PHPExiftool\Writer;
  use PHPExiftool\Driver\Metadata;
  use PHPExiftool\Driver\MetadataBag;
  use PHPExiftool\Driver\Tag\IPTC\ObjectName;
  use PHPExiftool\Driver\Value\Mono;

  $Writer = Writer::create();

  $bag = new MetadataBag();
  $bag->add(new Metadata(new ObjectName(), new Mono('Pretty cool subject')));

  $Writer->write('test.gif', $bag);

This should work:

require __DIR__ . '/vendor/autoload.php';

use Monolog\Logger;
use PHPExiftool\Writer;
use PHPExiftool\Driver\Metadata\Metadata;
use PHPExiftool\Driver\Metadata\MetadataBag;
use PHPExiftool\Driver\Tag\IPTC\ObjectName;
use PHPExiftool\Driver\Value\Mono;

$Writer = Writer::create(new Logger('exiftool'));

$bag = new MetadataBag();
$bag->add(new Metadata(new ObjectName(), new Mono('Pretty cool subject')));

$Writer->write('test.gif', $bag);
