Recursively strip final whitespace characters?
We'll get rid of every stray character in LaTeX one day...

A naked image using latex-image in a division will typically be authored in a way that ends like:
```
...
\end{tikzimage}
</latex-image>
</image>
```
This ends up in PTX-generated LaTeX as:
```
...
\end{tikzpicture}
}%
\end{image}%
```
There is a new line there at the end of `\end{tikzpicture}`. This newline is responsible for a small amount of horizontal space to the right of the picture. So if the picture is 100% width, it actually will not quite be flush with the right edge of the surrounding text body. Here you can see this with a naked image/tikz-image I put into the minimal article:
<img width="676" alt="Image" src="https://github.com/user-attachments/assets/e03f3bd3-8862-4f67-9dcf-6086f1315286" />
If I manually alter the tex, adding a `%` so we have:
```
...
\end{tikzpicture}%
}%
\end{image}%
```
then the image comes out at 100%.
I had trouble coming up with an automated way to get a `%` sign in there like that. The author's actual content has a text node like `...\end{tikzimage}
 `, so it's a question how you would insert that `%` there. And you wouldn't want to insert it before other newlines in the author's code. And counting the last line break is not reliable either since they may have additional line breaks at the end.
Maybe it's an unfortunate "author education" situation where they should author the `%` signs?

And you might even find an existing template in the file full of such things (pretext-text-utilities.xsl). Or else write a general enough one to go there.

Is that sort of stripping something to do in |
|
I think I would do it in the extraction and in the Latex. Maybe a template in common. Which is not to say assembly is bad, but there is a lot going on there.

Ah, I was already doing something in assembly and didn't see this first. Check out #2413 and let me know what you think. |
