PDFsharp & MigraDoc Forum

I was trying to use CMYK colour in my personal project where i am creating a new pdf from an original pdf and i intended writing text on each page with CMYK colour. Sometimes i need just Black and sometimes a mixture of all 4 primary colours. The issue is while using the Brush tool with latest PDFsharp nuget package downloded in my project in VB.Net (Visual Studio) I am getting contaminated or impure primary colours Cyan, Magenta, Yellow & Black. This Issue also persists with the Pen Tool - more or less.
How do i Solve this?
Am I doing something wrong or this is an unsolved issue with pdfsharp?
Does PdfSharp support ICC profile colours?
Been troubled with the issue for long now.

Thanks

Hi!

Have you set PdfColorMode to CMYK?

Yes colour Mode set to CMYK and still getting contaminated Black, Cyan, Magenta, Yellow with Brush element. With Pen element only Black is pure but Cyan, Magenta & Yellow still contaminated (other primaries showing some percentage of presence in resulting colour). The result is as checked with Adobe Acrobat 9.0 Pro Extended - Tool - Output Preview.
As with Pen element I can only draw lines. I need to use the Brush element to create Text on the pdf page.

Thanks for reverting back
