Feature request: GIF support in latexpdf builder

[kottkrig]

Repro Steps

1. Refence a GIF image in source files
2. Run make latexpdf

Expected: The GIF should be visible in the generated PDF. If it's an animated GIF, show the first frame.
Actual: make latex produces an error ! LaTeX Error: Unknown graphics extension: .gif. and the image is not visible in the generated pdf.

Citation from pdftex manual: "pdfTEX supports inclusion of pictures in png, jpeg, jbig2, and pdf formats."

Hence, the gif format is not supported. What you can do is convert the gif foo.gif to foo.png, then, according to

http://www.sphinx-doc.org/en/stable/rest.html#images

code in your .rst file:

.. figure:: foo.*

The LaTeX builder will then select the foo.png file and create the latex source to use it. Actually the html builder also, as I just tested. Seems to match this order:

supported_image_types = ['image/svg+xml', 'image/png', 'image/gif', 'image/jpeg']

from http://www.sphinx-doc.org/en/stable/builders.html#builders

Ah, there seems to be a bug in the LaTeX builder image supported types:

supported_image_types = ['application/pdf', 'image/png', 'image/gif', 'image/jpeg']

as, as said above, gif is not usable directly by pdflatex.

It seems media9 is the LaTeX way to include GIFs into PDFs. Until somebody builds support for that, I'd agree that removing image/png from LaTeXBuilder seems sensible.

I removed image/gif rom supported_image_types of LaTeX writer.

Now, pdflatex does not support GIF format. So we cannot support it at this present.
Please let me know if pdflatex supports it or commonly used package to do that appears.

Thanks,
