Writing text on a WriteableBitmap

Question

I have searched around and found that most of the answers convert a WriteableBitmap to a System.Drawing.Bitmap. I am currently thinking of using WriteableBitmapEx's Blitz() function to overlay a bitmap with text onto the existing bitmap, but I don't really find functions that return WriteableBitmap.

Is there a easy way to draw text?

Did you consider placing a TextBlock on top of an Image and then render their parent Panel into a RenderTargetBitmap? — Clemens, Jul 25 '17 at 08:43
@Clemens Nope. Do you have a simple example for me to start from? — John Tan, Jul 25 '17 at 09:15

I managed to use the WriteableBitmapEx DrawString() method to achieve this directly.

Unfortunately it is not inside the Nuget Packages so it has to be compiled from the source of another project:
