Code used by IguanaTex to extract information from displays generated with LaTeXiT on Mac and convert them into IguanaTex displays.
The end user should not need to fiddle with this code, but we make it public for reference.
LaTeXiT-metadata was kindly prepared by Pierre Chatelier, LaTeXiT's author, to meet IguanaTex's requirements. Many thanks to him!
LaTeXiT-metadata-MacOS takes as input a PDF or EMF file with encoded LaTeXiT source information, and creates a .tex file containing the encoded LaTeXiT source.
LaTeXiT-metadata-MacOS file.pdf/file.emf
will create a file file.tex with the LaTeX source.
Note that LaTeXiT itself does not create EMF files, but PowerPoint does in fact save PDF files internally as EMF files.
When using IguanaTex to edit a LaTeX display generated by LaTeXiT and inserted into a PowerPoint presentation as PDF, IguanaTex will extract the corresponding EMF file and run LaTeXiT-metadata-MacOS on it to retrieve the original LaTeX source.
The compiled LaTeXiT-metadata-MacOS executable can be downloaded from this release.
