The behavior of SVG output of Open Babel 2.4.1 seems different from that of Open Babel 2.3.2. With the new version, the output image always has a square bounding box and the margins around the structure are bigger. Should I crop the margins (using pdfcrop?) before including it to the LaTeX document?

Dear Maintainer!

I would kindly ask You to consider the possibility of adding a caption to the structure of the molecule - generated by Your LaTeX package; with options such as font size and colour.

This would be extremely helpful :-)

• Windows does not have "rm"
• Documentation: can "chemobabelimgdir" be changed via \renewcommand ? → No! (If "chemobabelimgdir" can be changed or user-defined "Prefix" is allowed, extra hacks on LuaTeX will be required. Twitter)
• Documentation: mention GitHub in the dtx/pdf also → Done (2022-09-19)

Adding the '-p' option to mkdir in chemobabel.sty will eliminate the reported error when the directory already exists.

I cannot build the document "chemobabel-example-ja.pdf"; it fails on including a PDF graphics from chemobabelimgdir/ subdirectory. (The graphics is actually generated properly.)

It seems that extractbb for images in subdirectory fails. For example, the following code passes on latex+dvipdfmx on TeX Live 2015 but fails on TeX Live 2022.

\documentclass[dvipdfmx]{article}
\usepackage{graphicx}
\begin{document}
\includegraphics{a/b.pdf}
\end{document}

! LaTeX Error: Cannot determine size of graphic a/b.xbb (no BoundingBox).

Praise your Project !!!!! Its hard to find another package that can transfer SMILES names to 2D structures in Latex !!
It really helps!

BTW, It seems that in the newest vewsion of inkscape, -f option is no longer allowed, while --export-pdf=${filename} is also deprecated and not available. So I use --export-type=pdf instead in chemobabel.sty, line 42:

% \newcommand\chemob@bel@inkscapecmd[2]{inkscape -f #1.svg --export-#2=#1.#2}
\newcommand\chemob@bel@inkscapecmd[2]{inkscape #1.svg --export-type=#2}

And it works for me now on Win10 PC.
Appreciate again!
