Previously we relied on graphicx internals and made global
changes to Gin to force images to be resized if they exceed
textwidth. This approach is brittle and caused problems
with `\includesvg` (see #9660).
The new approach uses a new macro `\pandocbounded` that is
now defined in the LaTeX template. (Thanks here to Falk Hanisch in
https://github.com/mrpiggi/svg/issues/60.)
The LaTeX writer has been changed to enclose `\includegraphics`
and `\includesvg` commands in this macro when they don't explicitly
specify a width or height.
In addition, the writer now adds `keepaspectratio` to the
`\includegraphics` or `\includesvg` options if `height` is specified
without width, or vice versa. Previously, this was set in the preamble
as a global option.
Compatibility issues:
- If custom templates are used with the new LaTeX writer, they will have
to be updated to include the new `\pandocbounded` macro, or an error
will be raised because of the undefined macro.
- Documents that specify explicit dimensions for an image may render
differently, if the dimensions are greater than the line width or
page height. Previously pandoc would shrink these images to fit,
but the new behavior takes the specified dimensions literally.
In addition, pandoc previously always enforced `keepaspectratio`,
even when width and height were both specified, so images with
width and height specified that do not conform to their intrinsic
aspect ratio will appear differently.
Closes#9660.
In some cases we need to break up a long text run including
both western and East Asian text, so that the punctuation in
the western text doesn't become double-wide.
Closes#9817.
It is supposed to replace emojis with their aliases,
but previously this only worked when the emojis were
in a specially marked span.
Note that this change doesn't affect `commonmark` (or `gfm`)
because the relevant code is in commonmark-hs. This will also
need updating.
See #9876.
- Turn captioned images into Figure elements. Closes#9391.
- Improve the logic for associating elements with captions.
Closes#9358.
- Ensure that captions that can't be associated with an
element aren't just silently dropped. Closes#9610.
...with width/height. That was a mistaken call in #6936.
Usually when these values disagree, it is because the image
has been resized by a tool that leaves the original exif values
the same, so the width/height metadata are more likely to be
correct that exif width/height.
Closes#9871.
...and only include it if `english` or `german` is used.
Since 3d8f011, the babel language is not specified as a
class option any more; so now we need to explicitly specify
the language option when we load `selnolig`. Only `german`
and `english` are valid, so we construct the variable
`selnolig-langs` in the writer and include `selnolig` if it
is nonempty.
This should restore proper ligature suppression when
lualatex is used.
Closes#9863. Supersedes #9864.
Thanks to @fkohrt for the initial fix.
The function allows to specify a template with the same argument value
that would be used with the `--template` command line parameter.
Closes: #9854

The state is an internal value and should be treated as such. The
`PANDOC_STATE` global is merely a copy; unsetting the global no longer
breaks the Lua engine.
