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.
