I’ve been trying to create a manga lines layout plugin, but I’m stuck. The lines are currently rendered on the canvas, and you can rotate the canvas, but when you zoom in, the lines become misaligned with the paper.

The only problem is the zoom in/out, if there are a solution to this because would be a great step to add this function to Krita.
Here is the code, test it in the scripter:
