如何在图片框上画线（多行），在缩放时保持相同的宽度？ [英] How to drawline (Multiple lines) on picturebox which keeps same width when zoomed?

问题描述

当我绘制多行（最多1000+）时，我想放大但保持线条宽度相同而不是缩放比例。目前我正在绘制图像（Bitmap）。放大时使线条变胖或缩小使线条变薄。我也试过图形绘制，这会导致很多平移和缩放图像丢失的问题。



我的技能水平很低所以请尽量保持简单。 />


提前谢谢。

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.

这里的关键是不要使用 PictureBox 。你可以，但它不会帮助你，只会增加麻烦，让你浪费你的开发时间和一些额外的系统资源。它完全没有意义，只有一些伤害。它只适用于最简单的静态物品。

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[^],
draw a rectangle in C#[^],
How do I clear a panel from old drawing[^].

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

That's all. Any further questions?
