Unable to Convert Pdf to Png Using Ghostscript.Net Visual Studio 2022

[longgreybeard]

Hello everyone and thanks for the help in advance. I am using GhostScript.Net to convert Pdf files to Png images. This has worked perfectly fine using Visual Studio 2019 on a Windows 10 OS. However, when I moved to VS 2022 I continue to receive an error "System.NullReferenceException" when trying to save the Png, Here is my code:

` using (var rasterizer = new GhostscriptRasterizer()) //create an instance for GhostscriptRasterizer
{

         string fileName = Path.GetFileNameWithoutExtension(inputFile);

         rasterizer.Open(inputFile); //opens the PDF file for rasterizing
         SendEmail sendEmail9 = new SendEmail("Page Count", rasterizer.PageCount.ToString(), "");

         //set the output image(png's) complete path
         var outputPNGPath = @"E:\out.png";

         //converts the PDF pages to png's 
         var pdf2PNG = rasterizer.GetPage(100, 1);

         //save the png's

         pdf2PNG.Save(outputPNGPath, ImageFormat.Png);

     }

pdf2PNG.Save(outputPNGPath, ImageFormat.Png); throws the error. I have installed gsdll64.dll, located in C:\Program Files\gs\gs9.56.1\bin. I'm not sure where to go from here Any help would be appreciated.`

I'm also having the same issue. GetPage returns a null value.
I'm using the 32-bit version of GhostScript (C:\Program Files (x86)\gs\gs9.56.1\bin)

Try adding this line to your code:
rasterizer.CustomSwitches.Add("-dNEWPDF=false");
