64 % StreamImageCommand() is a lightweight method designed to extract pixels
65 % from large image files to a raw format using a minimum of system resources.
66 % The entire image or any regular portion of the image can be extracted.
67 %
68 % The format of the StreamImageCommand method is:
69 %
70 % MagickBooleanType StreamImageCommand(ImageInfo *image_info,int argc,
71 % char **argv,char **metadata,ExceptionInfo *exception)
72 %
73 % A description of each parameter follows:
74 %
75 % o image_info: the image info.
76 %
77 % o argc: the number of elements in the argument vector.
78 %
79 % o argv: A text array containing the command line arguments.
80 %
81 % o metadata: any metadata is returned here.
82 %
83 % o exception: return any errors or warnings in this structure.
