C#窗口形式的外观精美的图形 [英] Good looking graphics in C# window form

问题描述

我需要使用C#在Windows窗体中创建一些简单的图形.简单来说，我指的是线条，圆形等.实心圆，其边缘不平滑(如使用正方形像素绘制圆时所预期的那样)，但是在矢量程序中以相同像素数绘制相同圆时，它看起来很完美.我已经在Inkscape中绘制了此示例.

I need to create some simple graphics in a windows form using C#. By simple I mean lines, circles etc. However, when I draw e.g. a filled circle, the edge is not smooth (as expected when drawing a circle using square pixels), but when drawing the same circle with the same number of pixels in a vector program it looks perfect. I have been drawing in Inkscape for this example.

也许矢量软件使用某种渲染功能来使颜色平滑，但这在C#中无需创建太多代码就可以吗?这是代码示例，它使用Graphics创建要绘制的画布.

Maybe the vector software uses some sort of render function to smooth the colors, but is this possible in C# without creating too much code? Here is an example of the code, which is using Graphics to create a canvas to draw on.

private void StatGraphicsPanel_Paint(object sender, PaintEventArgs e)
{
   Graphics canvas = e.Graphics;
   Brush brush = Brushes.Aqua;
   canvas.FillEllipse(brush, 0, 0, 10, 10);
}

解决方案 这段代码可以达到目的:

Solution This code does the trick:

private void StatGraphicsPanel_Paint(object sender, PaintEventArgs e)
{
   Graphics canvas = e.Graphics;
   canvas.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
   Brush brush = Brushes.Aqua;
   canvas.FillEllipse(brush, 0, 0, 10, 10);
}

推荐答案

您要使用

You want to use the System.Drawing.Graphics.SmoothingMode property. Before beginning to use your Graphics object, do this:

canvas.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;

那应该给你一个漂亮的抗锯齿的椭圆，而不是默认的锯齿状的椭圆.

That should give you a nice anti-aliased ellipse instead of the default jaggy one.

类似地，如果要在图像中绘制高质量的文本，请使用

Similarly, if you want to draw high-quality text in an image, use the System.Drawing.Graphics.TextRenderingHint property.

正如其他人在评论中提到的那样，您可能需要考虑使用WPF. WinForms已过时.

As others have mentioned in comments, you might want to consider using WPF instead. WinForms are dated.
