HylaFAX The world's most advanced open source fax server |
So imagemagick saw them as black as well and then you
inverted? wouldn't that make them all white? I guess I'm confused
now. I like the idea of running a script to post process them, as of now,
I'm having users open them in Adobe and then resaving them which corrects
the problem in the Microsoft (MODI) viewer, but its a very manual process.
Anything I can automate would be cool.

If the percentage is higher than 75% it inverts the image. It does a pretty good job of reducing our toner usage on printouts. -Brent Brad Stevens wrote: Mine is the opposite...Microsoft's Document images is what I was using, and it was black.

Brad, Your TIFF viewer is the problem... not HylaFAX. This is evidenced by the fact that PDFs are viewable fine. (Thus the tiff-to-pdf converterhas no problem with the TIFF.) Thanks, Lee.My company uses TIF format extensively for document archiving. I know that we have several volumes of documents that, when viewed with Microsoft Document imaging appear correctly, but when viewed with IrfanView appear to be white on black instead of black on white. Running them through the "negative" filter in IrfanView makes them view correctly. Strangely enough, going back and then viewing them with Microsoft's document viewer they are still correct. It's almost like some TIF viewers are just incorrectly interpreting the color palette in Group4 TIFs. |
