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 AUTHOR
