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

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.
currently no way to specify which bounding box is taken for

MediaBox. (Often only MediaBox is defined.) Moreover, the
