As seen from the image, the edges of eclipse is not smooth. I am using the following blend mode. Other modes produce more unwanted result.

enter image description here

writeableBmp.Blit(destRect, wbCircle, sourceRect, WriteableBitmapExtensions.BlendMode.Alpha);

Attached is the eclipse png. How do I remove the halo around the edges which only visible after the blit operation on Windows Phone?

Did you manage to resolve this issue? – Krzusztof Feb 21 '14 at 12:32
Unfortunately I didn't – PutraKg Feb 23 '14 at 05:06
To anyone having same problem, try BlendMode.Multiply. It's not the best solution and wont work for everybody. – Krzusztof Feb 24 '14 at 10:08
