问题描述
我找到了一段代码,可以在一个圆圈(即时钟或指南针)周围绘制文本,现在我需要绘制与其相伴的圆圈.
这是代码段...
I found a piece of code that draws text around a circle (i.e. clock or a compass), now I need to draw the circle that goes with it.
Here is the code snippet...
private void SetScale(Graphics g)
{
g.TranslateTransform(Width/2, Height/2);
float inches = Math.Min(Width / g.DpiX, Height / g.DpiX);
g.ScaleTransform(inches * g.DpiX / 2000, inches * g.DpiY / 2000);
}
private void DrawFace(Graphics g)
{
Brush brush = new SolidBrush(ForeColor);
Font font = new Font("Arial", 40);
float x, y;
const int numHours = 12;
const int deg = 360 / numHours;
const int FaceRadius = 450;
for (int i = 1; i <= numHours; i++)
{
x = GetCos(i*deg + 90) * FaceRadius;
y = GetSin(i*deg + 90) * FaceRadius;
StringFormat format = new StringFormat();
format.Alignment = StringAlignment.Center;
format.LineAlignment = StringAlignment.Center;
g.DrawString( i.ToString(), font, brush, -x, -y,format);
}
brush.Dispose();
font.Dispose();
}
private static float GetSin(float degAngle)
{
return (float) Math.Sin(Math.PI * degAngle / 180f);
}
private static float GetCos(float degAngle)
{
return (float) Math.Cos(Math.PI * degAngle / 180f);
}
}
问题是...如何使用画线或画圆来匹配圆周围的文字?感谢
Question is...how do I use drawline or draw the circle to match the text around the circle? thanks
