you can use rendertargetbitmap create image uielement contains in visualtree.

  var rendertargetbitmap = new rendertargetbitmap();   await rendertargetbitmap.renderasync(uielement);    var pixels = await rendertargetbitmap.getpixelsasync();    var logicaldpi = displayinformation.getforcurrentview().logicaldpi;   var encoder = await bitmapencoder.createasync(encoderid, stream);   encoder.setpixeldata(       bitmappixelformat.bgra8,       bitmapalphamode.ignore,       (uint)rendertargetbitmap.pixelwidth,       (uint)rendertargetbitmap.pixelheight,       logicaldpi,       logicaldpi,       pixels.toarray());    await encoder.flushasync();    return rendertargetbitmap;
