ppmtoexr(1)		    General Commands Manual		   ppmtoexr(1)

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  val-
       ues.

       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 digi-
       tal cameras.
