Not to my knowledge. The technical problem with Delphi 5, is that it does not
natively support the variable arguments in function like TIFFGetField and such.
There are workarounds possible, but they are tiresome, and seeing that Delphi 5
is quite old now...

I disabled ojpeg support in current LibTiffDelphi. This disabled state is also
the default state of ojpeg support in LibTiff.

I've since tried enabling it, but my very first test images already, LibTiff
ended up reporting access violations and the like. I've found out that the ojpeg
module in LibTiff is badly maintained, for pretty much the same reason that I do
not offer a Delphi 5 LibTiff: too much work for too little gain.

So, for all practical purposes, it seems that the answer to this question is
simply 'no'.
