NAME
       extractbb, ebb - extract bounding box information from graphics files

SYNOPSIS
       extractbb [-v|-q] [-O] [-m|-x] file...

DESCRIPTION
       For  each  JPEG,  PNG, or PDF file given on the command line, extractbb
       extracts the bounding box information and writes it into  a  file  with
       extension  .xbb, together with some header information. These files can
       then be used by dvipdfmx or other programs. For PDF files,  the  number
       of  pages  and  the PDF version number are reported as well.  The input
       filename extension may be in upper or lower case.

       If called as ebb, the output is written in the ``bb'' format (and  with
       extension .bb) as used by dvipdfm.  Xbb may be defined as a synomym for
       extractbb on your system.

OPTIONS
       -v        Be verbose.
       -q        Be quiet.
       -O        Write output to standard output.
       -m        Write output in dvipdfm's ``bb'' format.
       -x        Write output in dvipdfmx's ``xbb'' format (default), which is
                 the same as that used by pdfTeX.

OUTPUT FORMATS
       Here are more details about the bb and xbb formats:

       The  original  ebb (from dvipdfm) ignored density information in bitmap
       images, and generated bounding boxes with 100px = 72bp = 1in.  Unfortu-
       nately, screenshots (especially) tend to look bad with this approach.

       So,  extractbb  (from  dvipdfmx)  uses  density information if present.
       Otherwise, it generates bounding box with 100px = 100bp.  This is  what
       pdfTeX does.

BUGS
       There  is  currently  no way to specify which bounding box is taken for
       PDF files. It will always be the first one  from  the  following  list:
       ArtBox,  TrimBox, BleedBox, MediaBox. (Often only MediaBox is defined.)
       Moreover, the reported bounding box always refers to the first page  in
       a PDF file.
