36% Stream is a lightweight tool to stream one or more pixel components of the
37% image or portion of the image to your choice of storage formats. It writes
38% the pixel components as they are read from the input image a row at a time
39% making stream desirable when working with large images or when you require
40% raw pixel components.

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.
