Difference

• LibAPNG is .NET Standard libary
• Extensions for WPF (.NET Framework)
  • Convert each PNG frame to BitmapSource objects
  • Create key frame animation, So you can display APNG to Image control using Storyboard.
• Remove XNA projects
• Update to Visual Studio 2019

Usages

APNG to BitmapSource objects

varapng=newAPNG("a.png");varbitmaps=apng.ToBitmapSources();// Save to PNG filesforeach(var(bitmap,index)inbitmaps.Select((item,index)=>(item,index))){using(varfileStream=newFileStream($"{index}.png",FileMode.Create)){varencoder=newPngBitmapEncoder();encoder.Frames.Add(BitmapFrame.Create(bitmap));encoder.Save(fileStream);}}

Display APNG to Image control

<ImageName="PngImage" />

varapng=newAPNG("a.png");if(apng.IsSimplePNG)PngImage.Source=BitmapFrame.Create(apng.DefaultImage.GetStream(),BitmapCreateOptions.None,BitmapCacheOption.OnLoad);elseapng.ToAnimation().CreateStoryboardFor(PngImage).Begin(PngImage);
