如何按像素添加路径？ [英] How to add path by pixels?

问题描述

我有：

I have:

GraphicsPath path = new GraphicsPath();

我想按像素添加路径，而不是逐点。



Point Class不匹配，因为它增加了最小2像素而不是一个。

I wanna add a path by pixels, not by point.

Point Class doesn't match, because it adds minimum 2 pixels, not one.

private void Draw(object sender, System.Windows.Forms.PaintEventArgs e)
{
    e.Graphics.DrawLine(Pens.Red, 10, 10, 10, 10); // Adds nothing.
    e.Graphics.DrawLine(Pens.Red, 10, 10, 11, 10); // Adds 2 pixels.
}

推荐答案

Graphics类没有SetPixel方法。



我认为你需要研究 Bitmap.SetPixel方法 [ ^ ]



或者您可以通过平台调用使用GDI函数。

C＃GetPixel和SetPixel [ ^ ]



这取决于您的其他要求适合您。

The Graphics class doesn't have a SetPixel method.

I think you need to look into Bitmap.SetPixel Method[^]

Or you can use GDI functions via Platform Invoke.
C# GetPixel and SetPixel[^]

It depends on your other requirements what is suitable for you.
