DrawText text looks not clear in SurfaceImageSource unlike in SwapChainBackgroundPanel

Question

Hi, I tried to make Text Reader for Windows Store App. For draw text,  I used DirectX (SharpDX) and Direct2D's DrawText method. 

When I draw text to SwapChainBackgroundPanel (full screen directx), the text is very clear. But I draw to SurfaceImageSource completely same text, the text was very blurred.

The class which I used to draw text is here. http://pastebin.com/afc79uyA

Then, SurfaceImageSource and SwapChainBackgroundPanel are implemented like this. (SharpDX official sample)

I used SurfaceImageSource to fill Rectangle class (XAML). Then result image is here.

I can't figure out what is problem. How can I draw text clearly to SurfaceImageSource ?

Answer 1

I solved this problem myself :)

The reason is Stretch property of ImageBrush. To solve this problem, se to Stretch mode to Stretch.None.
