我需要通过C#Graphics绘制Google标记图像 为此我需要谷歌标记的确切坐标 我该怎么办请帮助。 我目前的守则是。
private void Shape8(PaintEventArgs e)
{
e.Graphics.SmoothingMode = SmoothingMode.AntiAlias;
int startMarker = 0;
int MarkerDiameter = 30;
int EllipseDiameter = 15;
const int StartX = 150;
const int StartY = 350;
int X = StartX;
int Y = StartY;
GraphicsPath path = new GraphicsPath();
Rectangle ellipse = new Rectangle(X, Y, EllipseDiameter, EllipseDiameter);
path.AddEllipse(ellipse);
path.CloseFigure();
X = X + (EllipseDiameter / 2) - (MarkerDiameter / 2);
Y = Y - (EllipseDiameter * 2) - (MarkerDiameter / 2);
startMarker = StartY - 10 - (Convert.ToInt32(MarkerDiameter * 1.5));//Space Between marker and circle.
AddMarker8(ref path, X, startMarker, StartX, StartY, EllipseDiameter, MarkerDiameter, "Concept1");
e.Graphics.FillPath(Brushes.Pink, path);
e.Graphics.DrawPath(Pens.Black, path);
e.Graphics.FillEllipse(Brushes.White, ellipse);
path.CloseAllFigures();
}
private void AddMarker8(ref GraphicsPath path, int X, int Y, int StartX, int StartY, int EllipseDiameter, int MarkerDiameter, string conceptName)
{
float startAngle = 180.0F;
float sweepAngle = 180.0F;
int fontStyle = (int)FontStyle.Regular;
path.AddString(conceptName, new FontFamily("Arial"), fontStyle, 15, new Point(X + (MarkerDiameter / 2), Y - 15), lblFormat);
Rectangle rect = new Rectangle(X, Y, MarkerDiameter, MarkerDiameter);
path.AddArc(rect, startAngle, sweepAngle);
Point lastpoint = new Point(X + (MarkerDiameter / 2), (Y + (MarkerDiameter * 2)) - (MarkerDiameter / 2));
path.AddCurve(new Point[] {
new Point(X+(MarkerDiameter), Y + (MarkerDiameter / 2)), //a
new Point((X +MarkerDiameter)-(MarkerDiameter/4) ,(Y +(MarkerDiameter ))) ,//A.5
lastpoint ,//c
new Point(X +(MarkerDiameter / 4) ,(Y +(MarkerDiameter ))) ,//B.5
new Point(X, Y + (MarkerDiameter / 2))//b
}, 0.5f);
path.CloseFigure();
}
答案 0 :(得分:0)
尝试以下代码
private void DrawMarker(int X, int Y, double Scale, Color BorderColor, Color FillColor, PaintEventArgs e, char Letter = '\0')
{
Graphics G1 = e.Graphics;
Pen Pen1 = new Pen(BorderColor, 8);
SolidBrush Brush1 = new SolidBrush(BorderColor);
SolidBrush Brush2 = new SolidBrush(FillColor);
G1.SmoothingMode = SmoothingMode.AntiAlias;
G1.ResetTransform();
G1.ScaleTransform(Convert.ToSingle(0.4 * Scale), Convert.ToSingle(0.4 * Scale));
GraphicsPath GraphicsPath1 = new GraphicsPath();
GraphicsPath1.AddBeziers(new Point(X + 51, Y + 169), new Point(X + 47, Y + 137), new Point(X + 42, Y + 107), new Point(X + 14, Y + 77));
GraphicsPath1.AddBeziers(new Point(X + 87, Y + 77), new Point(X + 62, Y + 107), new Point(X + 55, Y + 137), new Point(X + 51, Y + 169));
GraphicsPath GraphicsPath2 = new GraphicsPath();
GraphicsPath2.AddEllipse(X + 5, Y + 5, 92, 92);
G1.FillPath(Brush2, GraphicsPath2);
G1.DrawPath(Pen1, GraphicsPath2);
G1.SetClip(new Rectangle(X, Y + 85, 103, 84));
G1.FillPath(Brush2, GraphicsPath1);
G1.DrawPath(Pen1, GraphicsPath1);
G1.ResetClip();
if (Letter != '\0')
{
Font Font1 = new Font("Arial", 52, FontStyle.Bold);
StringFormat StringFormat1 = new StringFormat
{
Alignment = StringAlignment.Center,
LineAlignment = StringAlignment.Center
};
G1.DrawString(Convert.ToString(Letter), Font1, Brush1, new Rectangle(X, Y, 103, 103), StringFormat1);
Font1.Dispose();
StringFormat1.Dispose();
}
else
{
G1.FillEllipse(Brush1, new Rectangle(X + 32, Y + 32, 37, 37));
}
Pen1.Dispose();
Brush1.Dispose();
Brush2.Dispose();
GraphicsPath1.Dispose();
GraphicsPath2.Dispose();
}
private void Form1_Paint(object sender, PaintEventArgs e)
{
DrawMarker(0, 0, 0.5, Color.Black, Color.Tomato, e, Convert.ToChar("A"));
DrawMarker(80, 0, 0.8, Color.Black, Color.Red, e, Convert.ToChar("B"));
DrawMarker(160, 0, 1, Color.Black, Color.Linen, e, Convert.ToChar("C"));
DrawMarker(210, 0, 1.3, Color.Black, Color.Orange, e, Convert.ToChar("D"));
DrawMarker(260, 0, 1.6, Color.Black, Color.Green, e);
}
运行后,结果应该是这样的
