% ConjureImageCommand() describes the format and characteristics of one or

% more image files. It will also report if an image is incomplete or corrupt.
|

% The information displayed includes the scene number, the file name, the
|
||
% width and height of the image, whether the image is colormapped or not,
|
||
% the number of colors in the image, the number of bytes in the image, the
|
||
% format of the image (JPEG, PNM, etc.), and finally the number of seconds
|
||
% it took to read and process the image.
|

%
|

% The format of the ConjureImageCommand method is:

% MagickBooleanType ConjureImageCommand(ImageInfo *image_info,int argc,

% char **argv,char **metadata,ExceptionInfo *exception)

% o image_info: the image info.

%
|

% o argc: the number of elements in the argument vector.
|

%
|
||
% o argv: A text array containing the command line arguments.
