Does PDFNet SDK support CMYK / Alpha Transparency ?

Q:

Does PDFNet SDK support CMYK colour scheme for print?

Also does the software have the ability to import and support Alpha
Transparency in an
Adobe PDF 1.3 version?
--------
A:
PDFNet supports reading/writing/editing graphics that uses CMYK color
space (or any other color space supported by PDF specification -
including DeviceN, ICC, CIE, Indexed, Pattern, etc).

You can also use PDFNet to associate alpha channel with any image
object (as part of PDF 1.3 imaging model). PDFNet also supports
transparency features introduced with PDF 1.4.
