Hello,
I'm using conTeXt as the renderer in a XML workflow and have run into a problem with externalfigure. When a user chooses to include a PNG, PDF, or JPG image with an extension that is capitalized (or more generally, not all lower case), the externalfigure just includes a grey box like it can't find the file. The snippet below illustrates the problem. Note that I'm able to include the image by renaming the file to IMG_0103.jpg and changing the externalfigure to the corresponding filename.
\starttext
\externalfigure[IMG_0103.JPG]
\stoptext
I tried adding type=jpg and/or method=jpg to the externalfigure arguments, but the file did not compile.
I found that by adding the entry "\definefileinsertion{tpd}{JPG}{\handlepdfimage}" to the spec-tpd.tex file in the context distribution, the externalfigure is able to include this image correctly. Should the mappings in these files be case insensitive?
I'm sure that I'm missing something basic. Could someone please enlighten me?
Cheers,
Mike Santy

That is a bit odd, I thought that should have worked. But:

This makes sense. So much so that perhaps it could be added to the
core spec-tpd.tex file.
For now however, putting that line in your local cont-sys.tex is
probably better, otherwise you will have to remember to reapply
your fix at each context update you do.

You could consider using a case-insensitive file system to store
your data on, and lowercasing all entity input to ConTeXt, but
that is more clumsy than the extra \definefileinsertion-s.
Best wishes,
Taco

Hans,
You asked me to remind you this week to look into problems externalfigures and filenames with uppercase extensions. Have you gotten a chance to look into the problem?
Cheers,
Mike

Personally, I thought that
\externalfigure[MY_FIGURE.JPG][method=jpg]
was supposed to work. But it doesn't, so I must have
misunderstood something also. It seems its more related to
choosing between e.g. MY_FIGURE.jpg and MY_FIGURE.pdf
Best wishes,
Taco

I think it would make more sense for conTeXt to first convert an image's extension to lower case before trying to figure out rule to apply. Otherwise in order to be correct, you would need an entry for
"Jpg", "jPg", "jpG", "JPg", "JpG", and "jPG" -- not even counting the permutations for "jpeg".

I don't think a case-insensitive FS is going to be an option for us (*nix only).
Back to my original question, should "\externalfigure[MY_FIGURE.JPG][type=jpg] work? Or am I misunderstanding the meaning of the type parameter?
Cheers,
Mike
