RMagick can also be used to get an image size (and to change images in  
many  
ways.  
Use,e.g.,  
cheetah = Magick::Image.ping(“Cheetah.jpg”) »

[Cheetah.jpg JPEG 1024x768 DirectClass 8-bit 101684b]

p cheetah[0].rows » 768

p cheetah[0].columns » 1024

see :  
\_[RMagick 1.15.0: class Image (class and instance methods, part 1)](http://www.simplesystems.org/RMagick/doc/image1.html#ping_)  
([RMagick 1.15.0: class Image (class and instance methods, part 1)](http://www.simplesystems.org/RMagick/doc/image1.html#ping))

Best regards,

Axel
