bbox [ -l ] [ -r ] [ -h ] [ -V ] [ rawpbmfile ]
bbox reads a rawppm or rawpbm file and prints out the bounding box of the image (as postscript comment and in postscript points, i.e. 1/72dpi) as well as the high resolution bounding box. Input is read from standard input if no filename is specified. Example output:
%%BoundingBox: 12 253 829 837 %%HiResBoundingBox: 12.500000 253.000000 828.500000 837.00000
bbox has only very limited memory requirements as it reads the input line by line and thus needs to store only one picture line in memory.

Special thanks goes to Michael Sharpe from UCSD who suggested a lot of improvements for bbox to become more precise and robust, especially for small drawings.

Though the code is quite small and the probability for bugs is now small, there may be some left somewhere between the lines. In case you find one, please send a short description with bbox version number to <email@example.com> (please allow some time to reply).
