Windows OCR engine fails to recognize the text in canvas (converted to bitmap)

Question

I have a cordova project where I have a \"scribble pad\" where the user can scribble their notes. This is a simple canvas object, and I\'d like to get the OCR Engine to convert

Answer 1

well, that was rather embarrassing to realize that the reason why the OCR failed to read anything, even a system written text was that the resulting, generated image had a transparent background. Once I've included a rectangle with the white fill it all started to work correctly.

Unfortunately, the OCR is struggling to recognize anything I scribble on the canvas, so e.g. handwritten numbers or multiline text in canvas are not being recognized, see below

Then I've found Windows.UI.Input.Inking namespace and I reckon that's the only way to go.
