Getting an MNG to only play a set number of times instead of looping

[Vandalhart]

I have been going down rabbit hole trying to get my assembled/written MNG to not loop.

        using (MagickImageCollection mngCollection = new())
        {
            int frame = 0;
            uint frameRate = FramesPerSecond; 
            do
            {
                mngCollection.Add(exportFolder + "/" + expFileName + "_" + frame + ".png");
                mngCollection[frame].AnimationDelay = frameRate;
                mngCollection[frame].AnimationTicksPerSecond = 1;
                frame++;
            } while (File.Exists(exportFolder + "/" + expFileName + "_" + frame + ".png"));

            mngCollection[0].AnimationIterations = 1;
            mngCollection.Write(exportFolder + "/../" + expFileName + ".mng", MagickFormat.Mng);

        }

I have attempted to do so with the AnimationIterations but I don't think it's available on MNG files. Originally I attempted to adjust on the entire collection with not success and then I attempted to adjust it on the first frame of the file but it also didn't seem to take.

This is a class within a larger C# script where the frameRate is user defined before kicking it off.

Here is some additional information that may be useful:

I am using Unity 2022.3.25f1, C# and this was a diagnostic output from a script you supplied: Magick.NET Assembly: Magick.NET-Q8-AnyCPU v14.10.0.0
UnityEngine.Debug:Log (object)
MagickDiagnostics:Start () (at Assets/Diagnostic/MagickDiagnostics.cs:12)

Location: D:\Unity_Projects\LightRemap\Assets\Plugins\Magick.NET-Q8-AnyCPU.dll
UnityEngine.Debug:Log (object)
MagickDiagnostics:Start () (at Assets/Diagnostic/MagickDiagnostics.cs:13)

AnimationIterations available: NO
UnityEngine.Debug:Log (object)
MagickDiagnostics:Start () (at Assets/Diagnostic/MagickDiagnostics.cs:16)

I have been using CoPilot via Teams to get some assistance but that seems to have become a bit circular.

Setting the AnimationIterations on all the images to 1 should work? Maybe there is an issue with the tool that you are using to view the image?

I am using Jasc Animation Shop (which is very old) to view the image after, but the image will eventually be loaded onto a Linux machine for use.

Provided my loopDisable is a user enabled bool, should this work?

 do
        {
            mngCollection.Add(exportFolder + "/" + expFileName + "_" + frame + ".png");
            mngCollection[frame].AnimationDelay = frameRate;
            mngCollection[frame].AnimationTicksPerSecond = 1;
            if (loopDisable == true) { mngCollection[frame].AnimationIterations = 1; }
            frame++;
        } while (File.Exists(exportFolder + "/" + expFileName + "_" + frame + ".png"));
        mngCollection.Write(exportfolder + "/../" + expFileName + ".mng", MagickFormat.mng);

After attempting with this code block, it appears that the file is still set to loop.
