ras_formats - Information on raster formats supported by NCAR Graphics and NCAR View.

       Not all formats and encodings that are supported for output are supported for  input;  the  software  has
       separate input and output drivers for format/encoding pair.

       For  all  the  formats  listed  below,  only  8-bit  pixels  and 8-bit run-lengths (where applicable) are
       supported.

       Experience with HDF's "advanced" compression option indicates that you should use it only if you consider
       random pixels an advanced-appearing image.

       NCAR  Graphics  and  NCAR  View applications are built upon a common library that provides read and write
       access to raster imagery. The table below summarizes the support that is provided for all  the  different
       formats.   Note  that  a  format  may  be  writeable but not readable, and that a compressed image may be
       readable but not writeable. By default, a raster image is written as compressed if  possible.  For  those
       applications  that  key  upon the filename to determine the raster format, or allow a -ifmt or -ofmt, the
       extension, as listed below, should be used without the "."  in front (e.g. use "hdf", not ".hdf").
