NAME

       getinfo - get header information from a RADIANCE file

SYNOPSIS

       getinfo [ -d ][ file ..  ]
       getinfo -

DESCRIPTION

       Getinfo  reads the header of each RADIANCE file and writes it to the standard output.  Octree and picture
       files are in a binary format, which makes it difficult to determine  their  content.   Therefore,  a  few
       lines  of text are placed at the beginning of each file by the RADIANCE program that creates it.  The end
       of the header information and the start of the data is indicated by an empty line.  The -d option can  be
       used  to print the dimensions of an octree or picture file instead.  For an octree, getinfo -d prints the
       bounding cube (xmin ymin zmin size).  For a picture, getinfo -d prints the y and x resolution (-Y yres +X
       xres).  If no file is given, the standard input is read.

       The  second  form of getinfo with a hyphen simply removes the header and copies the body of the file from
       the standard input to the standard output.

EXAMPLE

       To print the header information from scene1.oct and scene2.hdr:

         getinfo scene1.oct scene2.hdr
