I have a working port of the libtiff library, version 3.8.2 and I'll
be looking to port 3.9.0beta as well as 4.0.0alpha in the next few
days.

I also have working tools,

but I don't know how to blend any of these with page(1), at the moment
the solution seems to be something like

	tiff2ps xyz.tif | page

It would be preferable to let page do the deciding, but I'm not sure
how to approach this.  Anybody who'd like to elighten me, please feel
free.

Mind you, I really believe page(1) needs some work, if only I could
figure out what are errors in it (partial black pages in TeX output,
for example) and what are misfeatures strictly from a personal point
of view.

PS: I still really need to concoct and document the approach I use
more or less automatically now to produce APE libraries and tools, but
of course this is not the fun part, so it gets somewhat neglected.  It
is also the reason why there are now two ports of "libtiff".  Binaries
are easy to supply, sources need a bit of work.

in /n/sources/contrib/quanstro/src/tiff there is a very poor tiff converter
i started several years ago.  i only mention it because it does interface
with page. for example
	tiff stamp.tiff|page
or
	tiff stamp.tiff
it may (or may not) be a useful example.

Does it produce Plan 9-format image files?  Right now, tiff2ps and
tiff2pdf will produce page(1) compatible outputs, but page(1) can
invoke a pipeline (the deceased tiff2pic, for example) to process what
it recognises as a TIFF file.  But tiff2ps and tiff2pdf won't do the
right thing in this case and I can't really reproduce tiff2pic, at
least not verbatim.

Also, when I tried the internal pipeline trick in the past, it turned
out not to be terribly practical when the files are in hundreds of
megapixels.  Still, suggestions are welcome, I stil don't really know
what page(1) wants to chew on, I can look at the source to figure it
out, but a few words by the right expert(s) will save a lot of
looking.

And any ideas on how to render extremely large images are also
welcome.

Then it's exactly the guidelines I need :-)

Thank you.
