Convert PDF with transparency to EPS without rasterization

I want to convert a PDF page containing one or more transparencies to EPS. This EPS will be used as the image in the PostScript file, which will eventually be converted back to PDF.

The output should remain vector, and not rasterized.

The PostScript file is created by a custom C # application that is automated on the server, so Adobe Acrobat is not allowed.

I understand that the native PostScript / EPS does not contain the full transparency function, but I believe that PostScript, which includes the advanced transparency operators Ghostscript or pdfmark, should fix this:

Ideally, I would like to use Ghostscript to convert PDF to EPS, which contains advanced Ghostscript transparency operators, then I could just include it in my PostScript file and convert the PostScript file to PDF again using Ghostscript.

Unfortunately, ps2write and eps2write always cause the entire page to rasterize when transparency is detected.

  • Is there a way to force Ghostscript to create an EPS that uses Ghostscript transparency operators instead of rasterization?

  • Also, does anyone know of another product that can convert PDF to EPS, which uses pdfmark to implement transparencies?

PostScript extensible Ghostscript operators for handling transparency in PostScript are not universal, so ps2write (e) does not use them.

There is absolutely no way (using Ghostscript) to create a PostScript file with transparent operations that are not displayed.

I do not know any application that can do this using pdfmarks.
