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.
