getinfo - get header information from a RADIANCE file
getinfo [ -d ][ file .. ]
getinfo
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.
To print the header information from scene1.oct and
scene2.pic:
getinfo scene1.oct scene2.pic
