NAME
       ra_t16 - convert RADIANCE picture to/from Targa 16 or 24-bit image file

SYNOPSIS
       ra_t16 [ -2 ][ -3 ][ -g gamma ][ -e +/-stops ] [ input [ output ] ]
       ra_t16 -r [ -g gamma ][ -e +/-stops ] [ input [ output ] ]

DESCRIPTION
       Ra_t16  converts  between  RADIANCE  and  Targa 16-bit or 24-bit RGB image files (type 2 in Targa's documentation).  In the default mode, a
       RADIANCE picture is converted to an RGB file of the same horizontal and vertical dimensions with 16-bits per pixel.  The  -3  option  tells
       the  program  to  produce a 24-bit image file instead.  The -g option specifies the exponent used in gamma correction; the default value is
       2.2.  An exponent of 1.0 turns gamma correction off.  The -e option specifies an exposure compensation in f-stops (powers  of  two).   Only
       integer	stops  are  allowed, for efficiency.  The -r option invokes a reverse conversion, from a 16-bit or 24-bit Targa file to a RADIANCE
       picture.  The determination of depth is made automatically on reverse translation, so the -2 and -3 options are not necessary.  If the out-
       put file is missing, the standard output is used.

BUGS
       Run-length encoded files can be read but not written with this program.
