No, to the best we could determine, and we had a guy who liked to get into the weeds of CCITT Group 3 and 4 compression, it was the raw images themselves, and there was nothing wrong with them, some just tickled a bug. If I remember correctly, their API required stripping off the header and presenting the OCR code with some metadata and the compressed image. It's been way too long for me to remember the details, except that it was fairly obnoxious to interface to, I couldn't just hand it a TIFF in some way (helped us VARs really "add value" and earn our keep :-).

We were producing our own TIFF files using our own software that drove monster Kodak ImageLink scanners (software I in fact took over, redid the SCSI driver of, and eventually did a clean rewrite of the engine on Sun workstations), so the images and their compression came straight from Kodak, and going further, I don't recall those 600 pound beasts ever screwing up at that level.

And this was way before Windows 98, it was Windows 3.0 or by then 3.1, like in 1992, Windows was utterly naive about document image files. Which I can see was a blessing (although maybe it was losing quality, I'd long switched to NT by the time 98 came out).
