|-O||Write output to standard output.|
|-m||Write output in dvipdfms bb format.|
|-x||Write output in dvipdfmxs 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.
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.
extractbb was written by the DVIPDFMx project team <email@example.com>, 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 K[:u]ster <firstname.lastname@example.org> wrote for the Debian GNU/Linux system. It may be used, modified, and/or redistributed by others without contacting the authors.
