+Here are more details about the bb and xbb formats:
+.PP
+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.
+.PP
+So, extractbb (from dvipdfmx) uses density information if present.
+Otherwise, it generates bounding box with 100px = 100bp. This is what
+pdfTeX does.
.SH "BUGS"
.PP
There is currently no way to specify which bounding box is taken
