This build should render correctly the border elements that were missing before:

Hi,

This stencil contains some embedded EMF images which cannot be rendered by WPF out of the box. You can convert them to WPF ImageSource using code below, and you will also need to add System.Drawing.dll as reference to your project.

private static ImageSource CreateImage(Stream stream)
{
	var image = new System.Drawing.Imaging.Metafile(stream);

	const int size = 256;
	using (var bitmap = new System.Drawing.Bitmap(size, size, System.Drawing.Imaging.PixelFormat.Format32bppArgb))
	{
		using (var graphics = System.Drawing.Graphics.FromImage(bitmap))
		{
			graphics.DrawImage(image, 0, 0, size, size);

			using (var memoryStream = new MemoryStream())
			{
				bitmap.Save(memoryStream, System.Drawing.Imaging.ImageFormat.Png);

				var result = new BitmapImage();
				result.BeginInit();
				result.StreamSource = memoryStream;
				result.CreateOptions = BitmapCreateOptions.IgnoreColorProfile;
				result.CacheOption = BitmapCacheOption.OnLoad;
				result.EndInit();

				return result;
			}
		}
	}
}

var stencil = VisioStencil.LoadFromXml(fileName, CreateImage); 

This build also extends support for cross-shape formula references necessary to render correct heights for the monitor shapes:

Quote:


While the stencil XML format itself is documented, there are many Visio API functions and objects referenced from shape formulas that are not and we must implement by guesswork. So you will have to send us the stencil files that don't work for our developers to investigate and we'll try to improve.

I hope that helps,

VisioStencil handles exceptions thrown by this callback and will try to decode the stream in formats supported by WPF if it catches any exception. You are probably seeing it because you have the 'stop when thrown' option enabled in exceptions dialog, but if you continue execution the stencil should still load.

You could probe for EMF headers first instead of directly calling constructor, this works for the monitors.vsx without exceptions:

var reader = new BinaryReader(stream);
var headerWord1 = reader.ReadInt16();
var headerWord2 = reader.ReadInt16();
var headerWord3 = reader.ReadInt16();
stream.Seek(0, SeekOrigin.Begin);

if (headerWord1 != 1 && headerWord1 != 2)
	return null;
if (headerWord2 != 0)
	return null;
if (headerWord3 != 108)
	return null;

var image = new System.Drawing.Imaging.Metafile(stream);
... 

If you see missing images from other stencils, they might be stored in another metafile format (e.g. WMF, EMF+) so you might have to add some checks for them too.

I hope that helps,

Are you using the last build?
