How to Import Images into Anki with LaTeX?

Question

For several days, I try to find an answer to my question, but without success.

In another question, it helped me to use "\ tikz" in Anki. Thank @gernot elsewhere.

I would like to include an image in an Anki card, using LaTeX language.

I know there are methods to include images in an Anki card that I found with Google, but it does not use LaTeX to insert.

In my previous question, I was given some advice, but for whatever reason it does not work. Thank you for your help.

I put the file in the td.png

@tym007 Yes, it is possible. Add \usepackage{graphicx} to the preamble, if it is not yet loaded by some other package (like pgfplots). Then [latex]\includegraphics{myfile.png}[/latex] should load the image. Some things may go wrong, though. Inspect tmp.tex and tmp.log, if it fails. E.g., if the image is too wide, use \includegraphics[width=3cm]{...}. If the filename or path contains special characters, you may need \string or \detokenize, see How to use tilde or space in includepdf filename?. – gernot Oct 10 at 20:34

@tym007 As a first test, use \includegraphics{example-image-a}. if you have a current TeXLive, then this image is on the search path. If this works, you know that any failures with your own images are due to either "image not found", "image too wide", or "strange characters in file name". – gernot Oct 10 at 20:38

@tym007 If the image is too big, then the preamble with the article class will generate a pdf with two pages, and the conversion to png fails (to be solved with [width=...]). The preamble with standalone will just cut the image, but not fail. – gernot Oct 10 at 20:44

In fact. For "\ usepackage {graphicx}" walking. We must put the image in the same file as the .tex. But on Anki, I do not know where to put it can be used with this function. An idea? – tym007 Oct 11 at 15:27

@tym007 Either give the full path, like \includegraphics{/usr/local/texlive/2016/texmf-dist/tex/late‌​x/mwe/example-image-‌​a.jpg}, or set the \graphicspath, or set the TEXINPUTS variable to include the directory with the images. If the file name or path includes spaces or special characters, see e.g. the answers to How to include graphics with spaces in their path?. For infos on \graphicspath, see the WikiBook on LaTeX/Importing Graphics. – gernot Oct 11 at 16:06

I try with this code, but it does not. '\includegraphics{/usr/local/texlive/2016/texmf-dist/tex/lat‌​‌​e‌​x/mwe/td.jpg}' – tym007 2 days ago

@tym007 How does tmp.tex look like? What does tmp.log say? What happens when you compile tmp.tex yourself? Does the image /usr/local/texlive/2016/texmf-dist/tex/lat‌​‌​ex/mwe/td.jpg really exist on your system? It doesn't on my system ... If td.jpg is your image, you have to use the path of this file instead of /usr/local/texlive/2016/texmf-dist... – gernot 2 days ago

Answer 1

Anki uses some temporary directory for compilation, so you have to give the path to your images explicitly. Suppose the directory is /home/gernot/anki and contains an image duck.jpg. Set the preamble in Anki via Tools | Manage Note Types | your cloze note type | Options to

\documentclass[12pt,border=1mm,varwidth]{standalone}
\usepackage{graphicx}
\graphicspath{{/home/gernot/anki/}}
\begin{document}

Add a card of your cloze note type with the following contents in the Text field:

[latex]\begin{center}\includegraphics{duck}\\\relax {{c1::duck}}\end{center}[/latex] 

Then Anki will generate the two cards

Some things to observe:

• The path in \graphicspath has to end with a slash /.

• Bare in mind that strings like {{c1::XXX}} will be replaced by [...] on one card and by XXX on the other one. You have to make sure that your code is correct in both cases. In the example above, writing \\{{c1::duck}} gives an error since \\[...] is interpreted as \\ with an optional argument. Writing \\\relax{{c1::duck}} still gives an error, since the string becomes \\\relaxduck on the second card and \relaxduck is an undefined command. Therefore one has to put a space, a line end or {} inbetween.

• If the LaTeX code happens to contain double braces {{, it may be mistaken as Anki notation. Replace it by {%+new line+{ or, if acceptable from the LaTeX point of view, by { {.

• If the path or the file name of the image contains special characters (spaces, tildes, dots) one may have to take extra precautions. See How to use \graphicspath? \includegraphics: Dots in filename; but remember the last point about avoiding double braces.
