NAME
bbox - prints out the bounding box of a rawppm or rawpbm imageSYNOPSIS
bbox [ -l ] [ -r ] [ -h ] [ -V ] [ rawpbmfile ]
DESCRIPTION
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.
OPTIONS
- -h | --help
- Show summary of options.
- -V
- Show version of program.
- -r
- resolution of picture in dpi
- -l
- loose bounding box (integer bounding box is expanded by 1 point, hires bounding box is expanded by 0.5 points)
