[ Basic Info | User Guide ] Basic Information on cgdisp Purpose:
displays and overlays images on a PGPLOT device CGDISP
displays/overlays images via contour plots, pixel map
representations, vectors and scaled boxes on a PGPLOT device.
Upto 3 contour plots, one pixel map, one vector plot and one box
display may be overlaid in multi-panel plots of multi-channel
images. In addition overlay locations (plotted as crosses,
boxes, circles, lines or see-through) may be specified from an
ascii text file. Manipulation of the device colour lookup table
is available when you display with a pixel map representation
(formerly called a "grey scale") You may input up to seven
images. Up to three of these can be displayed via contour plots
and one can be displayed via a colour pixel map representation.
One vector amplitude image and one vector position angle image
(degrees; positive N -> E) can together be used to display a
vector map (e.g. polarization vectors). One image can be
displayed as small scaled boxes (see below) a
