put whole canvas size data with the shift of width and height, so it should be outside canvas
What I got:
draw image for whole canvas size
get only part of canvas (0.36% in each direction)
put it in the 0.36% of width and height
It seems like geiImageData and putImageData interpret the coordinates (canvas.width, canvas.height) in other way than drawImage or even fillRect which also works correctly. I calculated this scale, and it seems to be exactly 2.75 (0.36). The proportions are keeped.
My canvas size is 1/3 of screen width and proportion is 3:4. But as I checked, it does not affect scale.
When I replace canvas.width with the number, it is all the same.
Please, tell me if I am doing something wrong or what could cause this issue
