I have just upgraded fuelphp from 1.6 to 1.7. Everything seems to work fine except the following problem : When I manipulate images and save them, it works, but when I am adding a crop or a watermark, then I get the following error :
ErrorException [ Fatal Error ]: Call to protected method Fuel\Core\Image_Driver::_crop_resize() from context ''
And the same code was working in 1.6.
I tried GD and Imagik drivers, and I get the same behavior.
Backport the class from the 1.8/develop repository (it has already been fixed in there), or wait for the 1.7.1. maintenance release in a few weeks time.
