[magick-users] How can I use ImageMagick C API to get the Identify of Image such as Format and Geometry

[Wang Ting-KFN436]

Hi there, 
 
 
  I got a C++ API question.  I just wander if the ImageMagick provided a
C API that can get the Identify of the image such as the format and the
geometry. 
 
 As far as I know, there is a command : identify abc.gif can get the
format and the geometry of the image.
 
 however, I need to use a function which can implement that at the  my
C code, so if it possible for you to provide an API for this command? 
 
 
 thanks
