RA_PICT(1)                                                          RA_PICT(1)

NAME

       ra_pict - convert Radiance pictures to Macintosh PICT files

SYNOPSIS

       ra_pict [ -e +/- stops ] [ -v ] [ -g gamma ] [ infile [ outfile ]]

DESCRIPTION

       Ra_pict converts a Radiance picture, as produced by rpict (1) to a Mac-
       intosh PICT file. The picture will be a 24 bit PICT 2 picture, using  a
       single bit map (DirectRect).

OPTIONS

       -g gamma  This sets an explict gamma correction for the image. If it is
                 not specified, the default value of 2.0 is used.

       -v        Invokes verbose mode, and gives line on standard error giving
                 the size of the picture and the gamma correction used.

       -e +/- stops
                 Adjusts the exposure by stops.

       infile    Specifies the file to read the picture from. If none is spec-
                 ified, it takes it from standard input. If standard input  is
                 used, then the picture is sent to standard output.

       outfile   Specifies the file to send the PICT file to. If none is spec-
                 ified, it is sent to standard output.

EXAMPLES

           ra_pict mypict.hdr mypict.pict

       Will convert the Radiance picture mypict.hdr, giving the Macintosh PICT
       mypict.pict.

           ra_pict -g 2.2 mypict.hdr mypict.pict

       Will convert the file using a gamma of 2.2.

BUGS

       Does  not yet do Macintosh PICT to Radiance PIC, as this PICT files are
       a lot more complex than just one bit map. This is left as  an  exercise
       for the reader :-)
