在C#（.net）中实现文字按指定的路径排列（沿线排版）

先看一下效果图：

这个的难点在于排版的算法上，其他的就是对GDI+中GraphicsPath的应用。以下为核心部分的源代码：

using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
using System.Drawing;
using System.Drawing.Imaging;
using System.Drawing.Drawing2D;

namespace Lgms.net.Drawing
{
    public enum PathAlign //文字在路径方向的对齐方向
    {
        Left = 0, //从第一点开始排列
        Center = 1, //居中排列
        Right = 2 //居右排列
    }
    public enum TextPosition //文字排列在路径上的位置
    {
        OverPath = 0, //路径之上
        CenterPath = 1, //路径中间，文字中心即路径经过区域
        UnderPath = 2 //路径下方
    }

    //基础类
    public class TextOnPath
    {
        private PathData _pathdataTOP;
        private string _textTOP;
        private Font _fontTOP;
        private Color _pathcolorTOP = Color.Red;
        private Color _colorTOP = Color.Black;
        private Color _fillcolorTOP = Color.Black;
        private PathAlign _pathalignTOP = PathAlign.Center;
        private int _letterspacepercentageTOP = 100;
        private bool _addsvg = false;
        private System.Text.StringBuilder _SVG;
        private int _currentPathID;
        private TextPosition _textPathPosition = TextPosition.CenterPath;
        public Exception LastError = null;
        public bool ShowPath = true;
        public TextPosition TextPathPosition
        {
            get { return _textPathPosition; }
            set { _textPathPosition = value; }
        }
        public PathData PathDataTOP
        {
            get { return _pathdataTOP; }
            set { _pathdataTOP = value; }
        }

        public string TextTOP
        {
            get { return _textTOP; }
            set { _textTOP = value; }
        }

        public Font FontTOP
        {
            get { return _fontTOP; }
            set { _fontTOP = value; }
        }

        public Color PathColorTOP
        {
            get { return _pathcolorTOP; }
            set { _pathcolorTOP = value; }
        }
        public Color ColorTOP
        {
            get { return _colorTOP; }
            set { _colorTOP = value; }
        }

        public Color FillColorTOP
        {
            get { return _fillcolorTOP; }
            set { _fillcolorTOP = value; }
        }

        public PathAlign PathAlignTOP
        {
            get { return _pathalignTOP; }
            set { _pathalignTOP = value; }
        }

        public int LetterSpacePercentage
        {
            get { return _letterspacepercentageTOP; }
            set { _letterspacepercentageTOP = value; }
        }

        public Bitmap TextOnPathBitmap(PathData _pathdata, string _text, Font _font, Color _color, Color _fillcolor, int _letterspacepercentage)
        {
            _pathdataTOP = _pathdata;
            _textTOP = _text;
            _fontTOP = new Font(_font, _fontTOP.Style);
            _colorTOP = _color;
            _fillcolorTOP = _fillcolor;
            _letterspacepercentageTOP = _letterspacepercentage;
            return TextOnPathBitmap();
        }

        //核心方法
        public Bitmap TextOnPathBitmap()
        {
            int i = 0;
            PointF[] _TmpPoints = null;
            PointF _TmpPoint = default(PointF);
            PointF[] _Points = new PointF[25001];
            //= oGP.PathPoints()
            int _count = 0;
            GraphicsPath _gp = new GraphicsPath(_pathdataTOP.Points, _pathdataTOP.Types);
