# IEEEtran - How to include ORCID in TeX/PDF with PdfLatex

This question led to a new package:
orcidlink

I would like to display the ORCID id in an author list in an IEEEtran pdf, like that:

Is there a standard way to include it in an IEEEtran article with PdfLaTeX? I used two approaches from Is there a standard way to include ORCID in TeX / PDF?, but I failed.

One is to insert the ORCID icon in the author list. I used the blow code:

\author{Ali Al-Obaidi \href{https://orcid.org/0000-0000-0000-0000}{\includegraphics[scale=1]{figures/orcid_16x16.png}}}


where orchid_16x16.png is provided in the link https://orcid.org/trademark-and-id-display-guidelines. But the result is that the icon is not clear enough, even I replaced it with a different size.

The other approach is to use the academicons package, like that:

\usepackage{academicons}
\definecolor{orcidlogocol}{HTML}{A6CE39}
\author{AAA \href{https://orcid.org/0000-0000-0000-0000}{\textcolor{orcidlogocol}{\aiOrcid}}}


However, the result is like that:

And I also got two errors: "Latex Error: Encoding scheme 'TU' unknown" and "Bad character code (59865)". In the latest academicons.sty (see ftp://ftp.dante.de/tex-archive/fonts/academicons/academicons.sty), academicons use the font TU. However, it seems that the compiler PdfLateX cannot support this font.

Thus, is there anyone that knows a standard way to include it in an IEEEtran article with PdfLaTeX? Please help me.

• \usepackage{academicons} doesn't work with pdflatex – Milo Aug 11 '18 at 2:25
• @Milo That's good to know. Are you aware of any alternatives that are compatible with pdflatex? – Amelio Vazquez-Reina May 13 '20 at 16:02
• @Milo The package ctan.org/pkg/fontawesome5 has the symbol \faOrcid and it runs with pdflatex. It can also be made green by {\color{orcidgreen}\faOrcid{}} (you need to define the color first) or similar. An alternative is the new ctan.org/pkg/orcidlink. – CampanIgnis Nov 22 '20 at 15:33
• @CampanIgnis For full clarity, the orcidlink package on CTAN explicitly notes that it is simply a packaging of the accepted answer on this thread. – E.P. Dec 6 '20 at 18:41

This answer has been packaged into the orcidlink package on CTAN by @duetosymmetry

Here is a pdflatex solution which uses tikz and the original .svg of the orcid icon.

Here are the steps:

1. Using the svg.path TikZ library you can faithfully replicate the icon.

2. I've used the scalerel package to scale the icon to the size of | (a vertical bar). This means it scales nicely with the size of the font. No special reason for choosing | other than it makes the size and placement roughly match the guidelines on the orcid website, which illustrate the icon placement should look something like this:

1. This has all been wrapped in a command called orcidicon which takes as an input the orcid code, e.g. \orcidicon{0000-0000-0000-0000}.

2. \href takes care of making it hyperlinked.

Note to get a bit of additional spacing after the logo I've used \, to add some thinspace.

Inspired by Using TikZ to create a custom word which combines an svg image and text

• Is there a way to male this work with the authblk package? First the \orcidicon command needs a protect there and then it completely garbles how more than one author is typeset... – quazgar Oct 11 '18 at 15:24
• Sorry, can't help with this. Perhaps you can ask a new question on the site with a MWE of your problem. – Milo Oct 11 '18 at 15:59
• FYI @Milo, I packaged up your command into a .sty file to make it simple for users, with credit to this answer. The style file can be found here: github.com/duetosymmetry/orcidlink-LaTeX-command – duetosymmetry Dec 12 '19 at 21:51
• @Milo I have not forgotten your "glasses symbol"....:-) – Sebastiano Aug 27 '20 at 15:35
• @duetosymmetry, could you publish the orcidlink.sty at CTAN? – FHZ Aug 27 '20 at 17:03
