61 % DisplayImageCommand() displays a sequence of images on any workstation
62 % display running an X server. Display first determines the hardware
63 % capabilities of the workstation. If the number of unique colors in an image
64 % is less than or equal to the number the workstation can support, the image
65 % is displayed in an X window. Otherwise the number of colors in the image is
66 % first reduced to match the color resolution of the workstation before it is
67 % displayed.
68 %
69 % This means that a continuous-tone 24 bits/pixel image can display on a 8
70 % bit pseudo-color device or monochrome device. In most instances the reduced
71 % color image closely resembles the original. Alternatively, a monochrome or
72 % pseudo-color image sequence can display on a continuous-tone 24 bits/pixels
73 % device.
74 %
75 % The format of the DisplayImageCommand method is:
76 %
77 % MagickBooleanType DisplayImageCommand(ImageInfo *image_info,int argc,
78 % char **argv,char **metadata,ExceptionInfo *exception)
79 %
80 % A description of each parameter follows:
81 %
82 % o image_info: the image info.
83 %
84 % o argc: the number of elements in the argument vector.
85 %
86 % o argv: A text array containing the command line arguments.
87 %
88 % o metadata: any metadata is returned here.
89 %
90 % o exception: return any errors or warnings in this structure.
