(PECL gmagick >= Unknown)
Gmagick::readimageblob — Reads image from a binary string
Reads image from a binary string.
Content of image
The image filename.
The Gmagick object on success
Wirft bei einem Fehler eine GmagickException.
If you want to be able to do the opposite (output your gmagick object to a blob), then use getImageBlob() like this:
$outputstring = $im->getImageBlob();
This is apparently undocumented here, but since the entire library is ported/modeled on the imagemagick library, it makes sense that it uses the same name as imagemagick.
