When I zoom out to see the full diagram, Zoom and Pan functions start to demonstrate ~1 Sec Lag.

Is it possible to improve the performance at this level of detail ?
or put it another way - at this count of objects ?

I have a simple question:
Does the ReaderWMF treats the gradient color?

Because I have test to import an EMF file with gradient color from my favorite software Visio 2003. After transformation, the XAML string contains a drawing with many SolidColorBrush as ressources but they are never used.

My image is white when I use :
Code:
Image myImage = metafileReader.GetGeometryFromHemf(hEmf, GeometrySettings.BasicOptimization);

It that a normal behaviour ?

In the same time, the 07 june, Microsoft released Studio 4 as free upgrade for Studio 3 owners. I was not aware of that.

The only improvement into Expression Design is the ability to import Windows metafiles (wmf) and Enhanced Metafiles (emf), making useless Paste2Xaml into my workflow.

I have the impression to have lost my money
