i tried it with ```cs var bm = BitmapFactory.decodeFile(Context, image_path_NPatch); var chunks = bm.getNinePatchChunk(); if (NinePatch.isNinePatchChunk(chunks)) { Log.d("NINEPATCH", "IS CHUNK YES"); //image.setImageDrawable(new NinePatchDrawable(bm, chunks, new Rect(), null)); } else {...

 valid 9 patch image `circle.9.png`

in android this works ```java Bitmap bm = decodeResource(getResources(), R.drawable.circle); // same as DecodeFile byte[] ninePatchChunk = bm.getNinePatchChunk(); if (NinePatch.isNinePatchChunk(ninePatchChunk)) { image.setImageDrawable(new NinePatchDrawable(bm, ninePatchChunk, new Rect(), null)); ```

hmmm it seems that Android's AAPT creates the 9-patch chunks itself, and the image does not actually contain these chunks (just the pixel info for these chunks) luckily we can...

and it can read it :)  ```cs internal class _10_test_png_chunk_reader : Test { internal class Reader : SKPngChunkReader { public bool r = false; protected override bool ReadChunk(string tag,...
