README
Adapted from dchesterton/image. Support panorama image.
The image metadata Library. Support panorama image.
Warning: This library is pre-alpha and much of it is a WIP or simply not working at all. Proceed at your own risk.
Supported image types:
- JPEG
- PNG
GIFPDFSVGWEBPTIFFDNGRAW FORMATS-CR2, NEF, etc.
Supported image meta types:
- XMP
- IPTC
EXIF
Get metadata
$image = Image::fromFile($filename); $headline = $image->getXmp()->getHeadline(); $camera = $image->getExif()->getCamera(); ...
Modify existing metadata
$image = Image::fromFile($filename); $xmp = $image->getXmp(); $xmp->setHeadline('A test headline'); $xmp->setCaption('Caption'); $image->getIptc()->setCategory('Category'); $image->save();
Standalone XMP
Generating standalone XMP
$xmp = new Xmp; $xmp->setHeadline('A headline') ... $data = $xmp->getXml();
Modifying standalone XMP
$xmp = new Xmp($data); // or Xmp::fromFile($filename) $xmp->setHeadline('A headline'); $data = $xmp->getXml();
Setting/replacing XMP in image
$xmp = new Xmp; $xmp->setHeadline('A headline'); ... $image = Image::fromFile($filename); $image->setXmp($xmp); $image->save() // or $image->getBytes()
Loading specific image type
When file type is known, you can load the file type directly using the file types' fromFile
method.
$jpeg = JPEG::fromFile('image.jpg'); $png = PNG::fromFile('image.png');
Instantiate from bytes
If you don't have a file to work with but you do have the image stored in a string (from database, ImageMagick etc.) you can easily instantiate an object from the string.
$data = ... $jpeg = JPEG::fromString($data); $jpeg->getXmp()->setHeadline('Test headline'); $jpeg->save('out.jpg'); // or $jpeg->getBytes();
Instantiate from GD or a stream
You can also create an object from a GD resource or a stream.
$gd = imagecreate(100, 100); $jpeg = JPEG::fromResource($gd);
$stream = fopen('...', 'r+'); $jpeg = JPEG::fromStream($stream);
Aggregate metadata
When just want a piece of metadata and don't care whether it's from XMP, IPTC or EXIF, you can use the aggregate meta object.
$image = Image::fromFile($filename); $headline = $image->getAggregate()->getHeadline();
By default it checks XMP first, then IPTC, then EXIF but you can change the priority:
$aggregate = $image->getAggregate(); $aggregate->setPriority(['exif', 'iptc', 'xmp']); $aggregate->getHeadline(); // will now check EXIF first, then IPTC, then XMP
You can also exclude a metadata type if you do not want to use it:
$aggregate->setPriority(['iptc', 'xmp']); $aggregate->getHeadline(); // will only check IPTC and XMP
You can also modify metadata on an aggregate level:
$image = Image::fromFile($filename); $image->getAggregate()->setHeadline('Headline'); $image->save();
This would set the headline in both XMP and IPTC. For maximum compatibility with other software it's recommended to use the aggregate metadata object where available.
Get GPS data
$image = ... $gps = $image->getAggregateMeta()->getGPS(); // checks EXIF and XMP // or $gps = $image->getExif()->getGPS(); $lat = $gps->getLatitude();
Set Panorama Image XMP Metadata
use Ycs77\ImageMetadata\Image; use Ycs77\ImageMetadata\Metadata\Panorama\GPano; $image = Image::fromFile($filename); $image->getXmp()->setPanorama(function (GPano $gPano) { return $gPano ->projectionType() ->usePanoramaViewer(true) ->croppedAreaImageWidthPixels(8192) ->croppedAreaImageHeightPixels(4096) ->fullPanoWidthPixels(8192) ->fullPanoHeightPixels(4096) ->croppedAreaLeftPixels(0) ->croppedAreaTopPixels(0) ->stitchingSoftware('Your App Name'); }); $image->save();
