extractbb, ebb - extract bounding box information from graphics files

extractbb was written by the DVIPDFMx project team <dvipdfmx@ktug.or.kr>, based on  the  program  ebb  by
       Mark A. Wicks.

       This  manual  page  was  also  written  by the DVIPDFMx project team, based on a manual page Frank Küster
       <frank@kuesterei.ch>  wrote  for  the  Debian  GNU/Linux  system.   It  may  be  used,  modified,  and/or
       redistributed by others without contacting the authors.

       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.

       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.

-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.

       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.   Unfortunately, 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.
