Transparency in XPS to PDF Conversion

[TomCrocker]

I'm evaluating Spire.PDF to replace another product and find I like the speed of Spire but the color rendering is off. Colors appear to lose their alpha channel. Fills layered on top of lines and other graphical elements completely hide the underlying material. I've uploaded screen captures of the problem.

Dear TomCrocker,

Thanks for sharing.
I have tested the file with the latest Spire.PDF Pack(Hot Fix) Version:3.9.285. I could get a correct result, please check on attachment.
And here is my testing code.

Code: Select all

            PdfDocument doc = new PdfDocument();
            doc.LoadFromFile(@"F:\MARS38A.Final Water.xps", FileFormat.XPS);
            doc.SaveToFile("11541.pdf", FileFormat.PDF);

Please try to use the version. If there is any question, welcome to get it back to us.
