.tex image extension in Image

[ickc]

Pardon me if this is mentioned elsewhere, and the lack of example because it seems the issue is simple enough to understand.

Say, for example, in source md,

![alt](image.tex)

When converted to tex, it becomes

\includegraphics{image.tex}
...

while the proper output should be

\input{image.tex}

Such .tex files for example can be in pgf or TikZ code generated by some other libraries.

Case like this is also not very well-defined, because .tex image can be anything. But I think a reasonable expectation is just to input them?

Well, this tex file really isn't an image -- it's tex instructions for creating an image.
so why not include it as raw TeX?

```{=latex}
\input{image.tex}
```

After all, it has no hope of displaying as an image in any other output format.

I was thinking more like having an image without extension in the source markdown, then use default image extension set to different ones (say svg for html and tex for LaTeX).

But you're right that the file isn't really an image and this behavior seems kind of arbitrarily defined. But if an Image has .tex extension, may be this is the only way that would make sense?
