---

“extractbb” is a program that exports the dimensions of an image or PDF file to a plain text format that is easily parsed by TeX. This tool is rarely ran directly by users, but is frequently used by packages running on XeTeX or upTeX. This package specifically contains a Lua-based reimplementation "extractbb" that behaves identically to the original C-based version distributed with dvipdfmx. There are two variants of “extractbb”: - “wrapper”: A wrapper script around the original "xdvipdmfx"-based “extractbb” that is used to fix a security vulernability in “xdvipdfmx”. - “scratch”: A standalone implementation of “extractbb”, written in Lua from scratch, with no dependencies on “xdvipdfmx”. Currently, the script “extractbb” defaults to the “wrapper” variant, but you can manually select any specific variant by setting the “TEXLIVE_EXTRACTBB” environment variable to either “wrapper” or “scratch”.
