Convert a CMYK pdf to a RGB pdf and PDF page manipulation

Q: I have some questions:


Is it possible to convert a cmyk pdf to a rgb pdf with PDFNetSDK?

Could you give me an code example which we convert cmyk to rgb pdfs?


Is it possible to trim the size of the PDF with PDFNetSDK?

Could we change the PDF page boxes?
