When I draw a multiple line (up to 1000+) I would like to zoom in but keep the line the same width & not at the zoomed scale. At the moment I am drawing to image (Bitmap). Which when zoomed in makes the line fat or zoomed out makes the line thin. I also tried graphics draw which caused a lot of issues with panning & zooming with image loss.

My skill level is low so please try to keep it simple.

In advance thanks.

The key here is not to use PictureBox. You could, but it won't help you, will only add hassles and make you waste your development time and some extra system resources. It makes no sense at all, only some harm. It is only good for simplest static things.

I'll tell you what to do instead. Please see my past answers:
Append a picture within picturebox[^],

Note that the last of these answers is focused on zoom implementation.

That's all. Any further questions?
