Extract object with specific spot color from a PDF

[michelm86735735]

Hello,

I have a PDF file containing some cutting marks as a spot color named "cutter". Is there a way with the PDF Library SDK to create a method that can output 2 files, one with only the cutting marks and the other without the cutting marks ?

Thank you for you answers

I have finally found a working solution for my request.

I walk in the pdf tree and look at the colorspace of the elements. If the color space is a separation named "Cutter", I remove this element.

At the end I have a new document without the "Cutter" separation.

Thank you.
