Thank you,

There are TIFF tags PHOTOMETRIC_MINISBLACK and PHOTOMETRIC_MINISWHITE
which tell the decoder if pixel with value 0 is black or white.
Look's like Imaging does not set the tag for binary images and the decoder programs
assume some default. The default for Irfan and MS Imaging is probably different.
I'll update the TIFF writer to set the tag explicitly.

EDIT: So it looks like there's some bug in MS Office Document Imaging that ignores the
PHOTOMETRIC_MINISBLACK tag. Binary images are always assumed to be PHOTOMETRIC_MINISWHITE.
Other MS programs (Paint, Explorer, ...) handle binary TIFFs saved by Imaging correctly.

Thank your answer,
and waiting your code!

Thank You again!  :)

One more question (Like Columbo's "one more thing")  :)

I'm using the TIFF 1bpp and it seems ok, but when the file opened with microsoft imaging the result is negative (with IrfanView is ok).

I have no idea!  :-[
Any suggestion?
Thank

Thank you for your work.
I try to get in touch with SVN as soon as I can, going to test 1bpp and tell you about it.
Thanks again. :)

Hi,
(first of all, sorry for my weak english  :D)
what do you think, how long does it take to upload the new wersion?
I would be grateful to you for it.  :)

Yes I'am interested in 1bpp, because i need to store a lot of multipages scanned documents.

Thank you very much for effort.

Hi,

I'm using vampyre and I'am content with it.  :D
But, i need to create black and white (1BPP) TIFF (with TTiffFileFormat), but it supported only ifGray8 (min).
How I can save TIFF 1BPP?
