NAME
       pfsinhdrgen  -  Create a	pfs stream with	different exposures defined by
       hdrgen script.

SYNOPSIS
       pfsinhdrgen <sample.hdrgen>

DESCRIPTION
       This program reads files	defined	in given  hdrgen  script  and  outputs
       them  in	 a  PFS	 stream.  Each	frame  has a tag BV with corresponding
       brightness value	(APEX standard). Larger	BV corresponds to  less	 expo-
       sure (darker image), necessary to capture a bright scene.

       The  generated  PFS  stream is to be used with photo-metric calibration
       software	and with generators of HDR images.

       HDRGEN script file is a plain text file in which	 each  line  contains:
       <path_to_an_image>     <inverse_of_exposure_time_in_seconds>	<aper-
       ture_size> <iso_speed> 0

       In most cases it	is convenient to use the jpeg2hdrgen program to	create
       such a file automatically. In case it could not parse the exif informa-
       tion from jpeg files, it	is necessary to	create this file by hand.  Be-
       low are the sample contents of such file:

       <---  cut  here:	 sample.hdrgen	/var/tmp/images/img08.jpg  4 2.8 100 0
       /var/tmp/images/img09.jpg 58.8235 2.8 100  0  /var/tmp/images/img10.jpg
       76.9231	 2.8   100  0  /var/tmp/images/img11.jpg  322.581  2.8	100  0
       /var/tmp/images/img12.jpg 400 2.8 100 0 <--- cut	here: sample.hdrgen

EXAMPLES
       pfsinhdrgen sample.hdrgen | pfsview

	      View exposures defined in	sample.hdrgen script.
