Is it possible to utilize Nokia Imaging SDK to overlay an image in real-time camera stream?
For example to put some kind of transparent logo in the corner of the image while user is using the camera in real-time?
So far I only managed to blend the logo over the image after it has been captured, but not in real-time (as some kind of blending filter).
My only idea at the moment is to use GetPreviewBufferArgb() for every frame, modify it using WriteableBitmap.Blit() extension from WriteableBitmapEx library, and then set that frame as the source of some image control in XAML. I'm afraid it wont be very optimized solution, so I'm wondering if Nokia Imaging SDK has an API for that kind of camera stream manipulation.
