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
