! LaTeX Error: Cannot determine size of graphic in ../images/vi.gif (no BoundingBox)

Question

I have downloaded https://hea-www.harvard.edu/~fine/Tech/vi.html file using wget -p -k https://hea-www.harvard.edu/~fine/Tech/vi.html then run pandoc --latex-engine=xelatex -o vi.pdf vi.html this produce -

pandoc: Error producing PDF from TeX source.
! LaTeX Error: Cannot determine size of graphic in ../images/vi.gif (no Boundin
gBox).

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.884 ...html}{\includegraphics{../images/vi.gif}}

And when I use pdflatex(default latex-engine in pandoc) by using pandoc -o vi.pdf vi.html this produce -

pandoc: Error producing PDF from TeX source.
! LaTeX Error: Unknown graphics extension: .gif.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

l.884 ...html}{\includegraphics{../images/vi.gif}}

I also use wkhtmltopdf https://hea-www.harvard.edu/~fine/Tech/vi.html to make pdf from weblink. But, in wkhtmltopdf solution I have no control over the background color. I want to make a black and white pdf.

Simple answer: gif is not supported by latex. Just convert your file to png or jpg or something that is supported. — TeXnician, Feb 12 '18 at 06:33
@TeXnician I know too. But, I want to make the conversion automated. — alhelal, Feb 12 '18 at 08:36
You can use Herbert's code and run pandoc with --pdf-engine-opt=-shell-escape — DG', Feb 15 '18 at 12:59
@DG' How can I use Herbert's code since I am not writing the code manually, I just call the pandoc with the html file. — alhelal, Feb 16 '18 at 00:48
Put the code in a FILE and call pandoc with the option --include-in-header=FILE — DG', Feb 16 '18 at 10:19

Take Herbert's code and put it in a file:

% file: gif2png.tex
% Herbert's code:
% https://tex.stackexchange.com/questions/7602/how-to-add-a-gif-file-to-my-latex-file/7608#7608

\usepackage{epstopdf}

\epstopdfDeclareGraphicsRule{.gif}{png}{.png}{convert gif:#1 png:\OutputFile}
\AppendGraphicsExtensions{.gif}

Now you can call pandoc with the options: --pdf-engine-opt=-shell-escape --include-in-header=gif2png.tex

Example:

Take this simple html file:

<!-- file: test.html -->
<p>Here is a gif:</p>
<img src="test.gif" title="A dummy picture" alt="The gif" />

And a gif called test.gif:

And run pandoc:

pandoc test.html --pdf-engine-opt=-shell-escape --include-in-header=gif2png.tex -o test.pdf

You will get this pdf as a result:

Caveat:

epstopdf supports only pdflatex and lualatex as pdf-engine

pandoc: unrecognized option--pdf-engine-opt=-shell-escape'` – alhelal Feb 16 '18 at 13:50
You are probably using an old version of pandoc. You can either install a more recent version or use the old option: --latex-engine-opt=--shell-escape. Cf. https://github.com/shd101wyy/markdown-preview-enhanced/issues/665 – DG' Feb 16 '18 at 15:42
Btw: Pandoc is well documented and you can get a list with all the options by calling pandoc --help and a lot of explanation by calling man pandoc, even when you are offline... – DG' Feb 16 '18 at 15:43

I upgraded my pandoc. Now, your solution works. – alhelal Feb 18 '18 at 01:16
