Hello Mr. Pashov,
ImageJ is a Java program that works with Tiffs very well, although it works with images, not faxes, I would imagine the process would be similar.
ImageJ's source can be found at: http://rsb.info.nih.gov/ij/developer/source/index.html
Browse to the ij.io.TiffDecoder and TiffEncoder classes and see how ImageJ reads and writes the X_RESOLUTION, Y_RESOLUTION and RESOLUTION_UNIT (tag numbers 282, 283, and 296 respectively). I think this should be a good way of reading and writing TIFFs in Java. You would just have to make the changes that would be specific for your application.
I hope you find this useful
(I have nothing to do with ImageJ except being a happy user who also believes it is a great tool for learning imaging in Java)
