     VIFF DATA FORMATS CONVERSION

     These routines change the data storage size/type of viff
     data.  The viff data structure supports multiple bands
     and/or pixel vectors.

     SHORT DESCRIPTION OF ROUTINES

     Data Type Convert - Convert a Khoros image from one data
                         storage type to another.

     Upcast Data -       Up converts all images to the highest
                         input image data type.

     Real to Complex -   Convert REAL data to COMPLEX form.

     Complex to Real -   Convert COMPLEX data to REAL form.

     Vector to Row -     Reformat data stored in vector format to
                         a single-band file where each vector
                         represents a separate row in the output
                         file.

     Vector to Band -    Reformat data stored in single-row vec-
                         tor format to a file where each vector
                         represents a single band in the output
                         file.

     Band to Vector -    Reformat data stored in image format to
                         a single-row file where each column
                         represents a separate vector in the out-
                         put file.

     Mosaic to Multiband -
                         Convert a mosaic input image to an out-
                         put image in which each subimage of the
                         input mosaic constitutes a band of the
                         output image.

     Combine Data Bands -
                         Combine all bands from specified images
                         into one multiband image.

     Extract 1 Data Band -
                         Extract a specified data band from a
                         multiband image.

     Extract 3 Data Bands -
                         Extract three data bands from a multi-
                         band image.

     Rectangular to Polar -
                         Conversion of Rectangular to Polar or
                         Polar to Rectangular Data.
