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
