Radiance psort program

PSORT(1)                                                              PSORT(1)

NAME

       psort - sort primitives in metafile as requested

SYNOPSIS

       psort [ +/-x ][ +/-y ][ +/-X ][ +/-Y ] file ..

DESCRIPTION

       Psort reads each metafile file in sequence and sorts primitives between
       globals according to the option specification.  Lower case options mean
       the  corresponding  minimum, upper case indicates the maximum value.  A
       '+' before the option means sort in order  of  increasing  values,  '-'
       means  decreasing.  The order the options appear on the command line is
       the order in which the extrema are examined.  For example, the  options
       -Y  +x  would  mean "sort on decreasing ymax, then increasing xmin val-
       ues".

       If no input files are specified, the standard input is read.

EXAMPLE

       To sort the file "meta" in order of increasing  xmax,  then  decreasing
       ymin:

         psort +X -y meta

FILES

       /tmp/psXXXXa /tmp/psXXXXb

BUGS

       Aborting the program will sometimes leave files in /tmp.
