## 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  in‐
       formation.  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  exten‐
       sion 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
### -q
### -O
### -m
### -x
                 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.  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.

## BUGS
       There is currently no way to specify which bounding box is taken for PDF files. It  will  al‐
       ways  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.
