If no information options are specified the default is to print +the center position and a radius (in decimal degrees if a WCS is present, +or in pixels otherwise). In all cases, in no WCS is present in the image +header, zero will be printed. +<P> + +If the <I>-b</I> option is used the LL and UR corner positions are printed +along with a rotation of the box that represents. The <I>-c</I> flag may be +used to explicitly print all four corner positions starting at the LL and +moving clockwise. The <I>-n</I> flag can be used to print the dimensionality +of an image, similarly the <I>-i</I> flag may be used to print all information +about an image determined by the task. +<P> + +By default, and MEF file will cause information about each extension to be +printed. If the <I>-a</I> flag is used the requested information for all +extensions in an MEF (e.g from a mosaic camera) will be printed. This allows +the user the option of getting information about individual rasters within +an MEF or the footprint of the entire FOV.
