The Gmagick object on success
错误时抛出 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.
