NAME

       ppmtoexr - convert a PPM image to OpenEXR format

SYNOPSIS

       ppmtoexr input.ppm output.exr

DESCRIPTION

       Converts  a  PPM  file  to  an  EXR file in [0,1].  If the input is 8 bit per channel, the input is gamma
       corrected according to the PPM standard.  Images which are  16  bit  per  pixel  are  treated  as  linear
       intensity values.

       This  program  works  with the 48 bit per pixel PPM files output by the dcraw program for converting from
       raw pixel formats found on many digital cameras.
