bbox - prints out the bounding box of a rawppm or rawpbm image
] [ -r
] [ -h
] [ -V
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
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.

- resolution of picture in dpi
- loose bounding box (integer bounding box is expanded by 1
point, hires bounding box is expanded by 0.5 points)

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
