[PATCH 2/3] [media] subdev-formats.rst: adjust tables size for LaTeX output

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There are two big tables here that are very hard to adjust its
size.

The first one would fit into one page, but the latex.py logic
at Sphinx auto-switches to longtable when there are more than 30
rows. There's no way to override without coding.

The second one is really big, and won't fit on a single page.
So, it has to use tiny font to fit.
