canvas.backdrop from sqlite db field

I’ve moved my images into an sqlite BLOB field and am changing my coding from reading the file from disk to populating a canvas from the database field.
I am using

Nothing has been set in the paint method of canvas1. The data is valid but the image does not show up in the canvas.


You wanted to show us how that should be coded :slight_smile: ?

Is there a question?

Do I get a prize if I get the right answer? :stuck_out_tongue:
