Magick.NET version

Magick.NET-Q16-AnyCPU

Environment (Operating system, version and so on)

Ubuntu 24.04.1 LTS, dotnet version: 6.0.136

Description

I'm currently running into an issue with Magick.net-q16-anycpu(14.4.0) added as a nuget package to .net6 application run on Ubuntu 24.04 LTS with GhostScript 10.03.1 and 10.04.0

When I run the same code, on Visual Studio on a Windows machine with the same GhostScript version, it runs fine and images are produced as needed.

As a note, I have been running this code on a prior version on Ubuntu 22 and that worked fine. This issue happened after I upgraded the Nuget packages and GhostScript.

Any thoughts on what could be causing this?

Am attaching a sample pdf that's having this issue.

Steps to Reproduce

Here's the code I wrote. Substituted some variables with dummies here but basically the same thing. The error happens at document.Write.

testfile.pdf

int startIndex = 0;
  int pageCount = 2;
  Parallel.For(startIndex, pageCount, new ParallelOptions { MaxDegreeOfParallelism = 4 }, pageIndex =>
  {
    
      MagickReadSettings settings = new MagickReadSettings()
      {
          FrameIndex = Convert.ToUInt32(pageIndex),
          Density = new Density(68),
        
      };

      try
      {
          using (MagickImage document = new MagickImage(filePath, settings))
          {
             
              string thumbnailFileName = $"Image{pageIndex}.png"
              string outputPath = Path.Combine(outputDirectory, thumbnailFileName);             

              document.Write(outputPath);

          }

      }
      catch (MagickException ex)
      {
	Log(ex)
      }   
  });

Is it possible to create a Dockerfile that can be used to reproduce this issue?

[yfjjacob]

Hi,

Sorry about the delay in response. I haven't worked with Docker or Dockerfiles before. Would you be able to clarify what you needed in the file?

[dlemstra]

With a Dockerfile it would be easier to create a sample that reproduces the issue. Because this allows you to create a "server" that is running the correct os and use the correct dotnet version. I can probably create this myself but it would make it easier for me if you would create that.
