在GDI和WinForms C＃径向渐变效果刷 [英] c# radial gradient brush effect in GDI and winforms

问题描述

我创建了一个C＃Windows应用程序编写的代码的75％。该程序允许用户创建的流程图，并且将遮阳根据其情况的流程图的形状。我希望他们成为的3D按钮，如从网站的 Webdesign.org

I have created a c# windows application and written 75% of the code. The program allows the user to create a flow chart, and will shade the flow chart shapes according to their status. I wanted them to become 3d buttons such as from the website Webdesign.org

而不是为每个按钮创建一个PNG ，我想在C＃创建它们用刷子或其它技术，如：

Rather than create a PNG for each button, I wanted to create them in C# using brushes or other technique, such as:

// Create solid brush.
SolidBrush blueBrush = new SolidBrush(Color.Blue);
// Create points that define polygon.
PointF point1 = new PointF(50.0F, 50.0F);
PointF point2 = new PointF(100.0F, 25.0F);
PointF point3 = new PointF(200.0F, 5.0F);
PointF point4 = new PointF(250.0F, 50.0F);
PointF point5 = new PointF(300.0F, 100.0F);
PointF point6 = new PointF(350.0F, 200.0F);
PointF point7 = new PointF(250.0F, 250.0F);
PointF[] curvePoints = {point1, point2, point3, point4, point5, point6, point7};
// Define fill mode.
FillMode newFillMode = FillMode.Winding;
// Fill polygon to screen.
e.Graphics.FillPolygon(blueBrush, curvePoints, newFillMode);

我知道WPF具有径向渐变，但我可以做一些simular在CGI？

I know WPF has radial gradients, but can I do something simular in CGI?

推荐答案

在这个看一看的 CodeProject上文章，然后在路径梯度。

Take a look at this Codeproject article, and then at the Path gradient.
