Imagick和GridFS

Question

I have images stored in GridFS for MongoDB. When I pull the image out, I want to resize it and then store it back into the database. I tried this:

$image = $grid_collection ->findOne(array('_id' => new MongoID($id)));
new Imagick($image -> getBytes());

But that throws an error in Imagick. Now I can write it out to file temporarily to disk and have Imagick read the file, but that seems the long way around. Any suggestions on a better way to do this?

Answer 1

Yes:

$data = $grid->findOne(array('_id' => new MongoID($id)));

$img = new Imagick();
$img->readImageBlob($data->getBytes());
