Fails with the same errors. Again, it works correctly by changing the extension.

I can't you whether you supposition is right because if Hans Hagen goes out of his way to avoid name collisions with graphics then it's good enough for me.

Yup, after a little debugging I came to the same conclusion, but I still it's incorrect behaviour. It's correct that it removes the jobsuffix from the figuretypes to be searched, but it should still try and look for the figure, after the change. -- Giuseppe "Oblomov" Bilotta ^ permalink raw reply [flat|nested] 11+ messages in thread

Remembering that i did look into it long ago, i took a look in the core-fig
file; now, if you really want this kind of support, open core-fig.tex and
search for:
% new, test first
uncomment the doifnumberelse lines and you'll have the support needed (a
new format needs to be generated)

For example, while .<num> are usually MP output, I could have other formats (embeddable by PDF) using those extensions. As long as I can specify [type=...] or [method=...], the extension should be left whatever it is. The problem arises because when the name of the included graphic is the same as the \jobname, extension is discarded. To be precise, two things are done: some extensions are discarded from the extensions searched, and then the extension of the file is wiped. While the first action is very wise (prevents output/input clash, so indeed tex, xml, pdf and dvi should be not searched in such a case), the second is not a good idea: after the suppression of the extensions, the inclusion should continue normally: we're safe from clash because the "wrong" extensions will not be searched.
