I received your tool, and it seems to work fine. Its a lot lot more than I expected, but I haven't had enough time to check for unintended consequences. So far, the ones I running into seem to be less of a bother than the photometric interpretation somehow being set or intrepreted wrongly. (Is there such a word? Oh well.) For example, most of my images, after being process by tiffcp and then your tifftweak, are coming out black letters on white now in both MS Imaging and MS Photo Editor. That's good. But some that were OK are becoming white letters on a black background in MS Imaging, yet still display OK in MS Photo Editor. What happens when they are "saved as" by either application is a whole 'nother story! I'm no quite sure yet why this behavior is occurring, but as I get more clues and hints from this list, I'm sure it'll be figured it out.
Thanks again for your help.

I have written the utility you are looking for so desperately. It's
a commandline Delphi app that is passed two parameters:
1 - The name of the TIFF file to modify 2 - The new value for photometric interpretation. The only legal values are 0 (white is the minimum value) or 1 (black is the minimum value).
Since it is a console app, it can be called from a batch file. It returns 1 on success and 0 on failure. If you have any problems, let me know. I have attached it to the message I sent to you directly. I didn't attach it to the general posting since most members probably don't want it. If any do, just let me know.
Your right on the link address. But I might have found another, and perhaps better way. There's a program in libtiff distribution called
tiffset.exe. Unfortunately, there are no instructions or help files. Executing it with no parameters results in some very terse instructions. I then tried using it to change the photometric interpretation from 1 to 0, but tiffinfo says it was changed to a big number. Consequently, either I need a more complete instruction set or I must conclude it doesn't work. Does anyone have a set of instructions for tiffset.exe?

Thanks for the links, I'll look at them later tonight. But the one
below returned a 404.

If you look closely, the link got word wrapped in my post. You'll need to manually cut and paste the first and second parts together to create the proper URL. Also, you can go to Google and try the search I mention and find the link there as well.
