getinfo

GETINFO(1)						      General Commands Manual							GETINFO(1)

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  RADI-
       ANCE  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
