WriteableBitmap lt you access the pixes of a bitmap

drawing text is not really simple. You have to simulate a font and by code write it pixel-by-pixel in the bitmap.

DRM stands for Digital Rights Management

Not so simple. You have to write the text and the image pixel by pixel using a WriteableBitmap. This because after using Render() on a WriteableBitmap it is locked due to DRM and you are unable to access pixels. So the only way is to write pixels and then read them.
