GIF animations with mixed disposal methods not handled correctly

[kikokuo]

Hi,
I found some gif file leak image. I using below code to handle flip and mirror. It worked great,
But some gif file leak image when using library to process save or transfrom.
How can I fix it or I miss some step?

PhotoSauce.MagicScaler.ProcessImageSettings processImageSettings = new()
{
	Width = gifPixelWidth,
	Height = gifPixelHeight,
	ResizeMode = PhotoSauce.MagicScaler.CropScaleMode.Stretch,
	HybridMode = PhotoSauce.MagicScaler.HybridScaleMode.Turbo
};

//Build pipeline And add orientation
using (var pl = MagicImageProcessor.BuildPipeline(m_sResourceFilePath, processImageSettings))
{
	using (var outfile = File.Create(sNewSourceFilePath))
	{
		if (IsVFlip)
			pl.AddTransform(new OrientationTransform(Orientation.FlipVertical));
		if (IsHFlip)
			pl.AddTransform(new OrientationTransform(Orientation.FlipHorizontal));				
		pl.WriteOutput(outfile);
	}
}

Thanks for the repro! The sample input you've provided has an unusual mix of frame disposal methods, which is not handled correctly in MagicScaler's animation optimizer. I'll get a fix pushed for that soon.

Thanks again for the report. The issue was quite a bit more complicated than I expected (I had made some invalid assumptions in my initial implementation), but it's finally fixed in 11e96cc
