HI Paul Kox
   thank your advice.

I readed the Tiff6.pdf file, especially CMYK section.

but I find it is difficult for me to write my program to read and write Tiff file,

I want to find a easy way to do it.

such as using somebody source code or changing a little.

Do you have these source code?

help me!

thank you advance

By the way for cmyk use PhotometricInterpretation ( tag 262 ) == 5 (see page 69)

I want to read and write CMYK color mode tiff image file.

but I don't know how to do it?

My purpose is that I read every channel of CMYK tiff file ,I decode it and Save the every channel to the memory, I dispose every pixel value of every channel of CMYK, then I code and write it to CMYK color mode file.

Do you give me advice?

   Thank you very much
