Folks,

Some of you may remember - I launched a request for OJPEG testfiles and
funding a little time ago.

Several people contributes testfiles. Many thanks! I've now enhanced my
prototype decoder to support all of these testfiles. As this prototype
decoder is inside my own proprietary TIFF codec, which is very different
from LibTiff, next some additional difficult translation into a version
that fits neatly into LibTiff is on the menu.

At this point, I would like to repeat my requests.

- It is crucial for this project that I get as many testfiles as
possible, from as many different sources as possible. There is no
unambigious specification - OJPEG specification never was unambigious.
There has never been much opportunity for lazy OJPEG writer vendors to
test the results of their code with other apps. The result is that OJPEG
is only defined by testfiles. Various flavors exist, various wild clear
bugs add to personal interpretation of ambigious spec. If I haven't got
testfiles to illustrate the vast majority of OJPEG writer
implementations, chances are the results of my effort are not going to
be very useful for you. If you have OJPEG images laying about, and
haven't yet posted them to me, please consider doing so.

- I have gathered some funds for this project. Not halfway enough to
justify the time I put in, though, not even at my lowest of low rates.

So, I guess you could say I'm the primary funder, myself. I nevertheless
decided to go ahead. But, if anyone at this stage should consider to
share a bit of this burden and contribute some funds, please let me
know.
