   I work on a c# project and I am asked to make CMYK tif file.

Task is quite simple.

I have textual file with included image witdh and height info in milimeters.

Little squrare is placed somewhere in image.

Little square has also width and height specified in milimeters and also top left corner coordinates.

Textual file gives also info about C,M, Y and K channel values for square color.

What I need to do is to make CMYK tif file with square painted with specified color and properly placed on white painted image.

How it is possible to do using libtiff.dll? GDI+ gives possibility to save RGB tif files.

Thanks in advance for every useful advice. Described task is simplified, but if it is done, everything other will be easy for me.
