Thank you, Gerben. You were very helpfull. However, i need to save image as CMYK tif

and GDI+ allows bitmap to be saved as tiff, but when you do it, you get RGB tiff and that

is not what I need. I need CMYK tif.

Of course, you would still have to retrieve the bitmap data from GDI+ and save it ***using libtiff***, just as I described in my first reply. It means working with byte buffers, but it's not hard. If you don't understand my first reply, please ask *on the mailing list*.

I do hope you know how to link to libtiff and how to use its interface from C#. I haven't tried that yet.

I wont to do this and than change image flags.

OK, you could write a C program to open the TIFF, convert it and write it back. This may be easier, yes. Use the flags I mentioned at the bottom of my first reply.

By the way, I think it would be helpful if you kept the rest of the discussion on the mailing list. Others may be interested, or be able to help, too.
