GhostScriptRasterizer shows a PageCount of 0 for all PDFs under GhostScript 9.27 about ghostscript.net

Fixed in today's v.1.2.2. release.

Still a problem and a huge waste of time. Ill try and get a fix submitted. Using GS 9.26 or commenting out the code below works

Ghostscript.NET\Ghostscript.NET\Viewer\FormatHandlers
GhostscriptViewerPdfFormatHandler.cs line 85 through 89

GS_PDF_ProcSet' and 'pdfdict' are private as of GS 9.27

        // open PDF support dictionaries
       // this.Execute(@"
         //       GS_PDF_ProcSet begin
          //      pdfdict begin");

seems to have already fixed it in their product.

We ran into the same issue, where v9.26 works fine, but v9.27 never finds any pages. We're using a 32 bit compiled version on .NET Framework 4 for building a Windows service.

I suspect that the "tidying" of the Postscript namespace done in v9.27 may be to blame here. See their changelog entry, specifically the "Incompatible changes" section, for more info.

I encountered a similar problem as well. Commenting out the code below seemed to fix the problem. I don't know anything about GhostScript / Postscript otherwise I would try to fix it.

// open PDF support dictionaries
//this.Execute(@"
// GS_PDF_ProcSet begin
// pdfdict begin");

Please find the changelogs below.

Fix lib/pdf2dsc.ps to use documented Ghostscript pdf procedures.

We eliminated GS_PDF_ProcSet and pdfdict, but runpdfbegin, dopdfpages,
and runpdfend are still available.

lib/pdf2dsc.ps

The same problem. Is there any fix ?

[deremakif]

Still same problem!

I have a similar problem. I wanted to use the viewer to display a PDF in a form. The events "DisplayUpdate" and "DisplayPage" are not called, only "DisplaySize". It does not work with version 9.52, only up to version 9.26.

same problem here on Ghostscript version 9.52

[thienquang07]

just went back to version 9.26 and it worked fine.
