- % DisplayImageCommand() displays a sequence of images on any workstation
- % display running an X server. Display first determines the hardware
- % capabilities of the workstation. If the number of unique colors in an image
- % is less than or equal to the number the workstation can support, the image
- % is displayed in an X window. Otherwise the number of colors in the image is
- % first reduced to match the color resolution of the workstation before it is
- % displayed.
- %
- % This means that a continuous-tone 24 bits/pixel image can display on a 8
- % bit pseudo-color device or monochrome device. In most instances the reduced
- % color image closely resembles the original. Alternatively, a monochrome or
- % pseudo-color image sequence can display on a continuous-tone 24 bits/pixels
- % device.
- %
- % The format of the DisplayImageCommand method is:
- %
- % MagickBooleanType DisplayImageCommand(ImageInfo *image_info,int argc,
- % char **argv,char **metadata,ExceptionInfo *exception)
- %
- % A description of each parameter follows:
- %
- % 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.
- %
- % o metadata: any metadata is returned here.
- %
- % o exception: return any errors or warnings in this structure.
