A TIFF with spot colors needs to be handled in a VERY SPECIAL way. First,
because it's not a standard TIFF (it uses some extensions to v6) and second
because you will need to use a DeviceN colorspace in PDF to make it work. So
you will need to write a bunch of additional code - first in the TIFF handler
to read all the extra bits of the TIFF to understand the structure of color
data - and then on the PDF side to re-encode that information in a PDF manner.

Subject: [Podofo-users] Podofo-Spot Color
Hi
I am facing problems adding a tiff image(CMYK+PANTONE 200 C)to a pdfpage using
PdfPainter.DrawImage .The tiff image include a PANTONE color.
I am using the "podofo-0.9.3" under windows. But i don't know how to use the
colospace " ePdfColorSpace_Separation" especially the function
"BuildColorSpace( PdfVecObjects* pOwner )".Do you have some example code for
this?
