Dear

I want to read/write a CMYK mode TIFF file, and I use TIFFReadRGBAImage to read it.

Then, I use TIFFWriteEncodedStrip to write it.

I also set 8 to TIFFTAG_BITSPERSAMPLE tag, 4 to TIFFTAG_SAMPLESPERPIXEL and PHOTOMETRIC_SEPARATED to TIFFTAG_PHOTOMETRIC.

However, the color tones of output file is different to the original file.

Why?

Can anyone tell me why and give me a sample code?

Thanks a lot.
