『尝试』随手绘制几张点阵图片

本文仅属 个人尝试，最终目的是实现 点阵图片 存储离线数据。

本文只包括 生成 点阵图片的代码，不包括 读取点阵图片。

    class Program
    {
        static void Main(string[] args)
        {
            
            int xp = 200;
            int yp = 55;

            for (int s = 3; s < 8; s++)
            {
                int width = xp * s + (xp - 1);
                int height = yp * s + (yp - 1);

                using (Bitmap bitmap = new Bitmap(width, height))
                {
                    using (Graphics g = Graphics.FromImage(bitmap))
                    {
                        g.Clear(Color.White);

                        for (int x = 0; x < xp; x++)
                            for (int y = 0; y < yp; y++)
                            {
                                int px = x * (s + 1);
                                int py = y * (s + 1);

                                //g.FillRectangle(new SolidBrush(RandomColor()), px, py, s, s);
                                g.FillPath(new SolidBrush(RandomColor()), GraphicsPath(px, py, s, s));
                            }
                    }
                    bitmap.Save(@"D:" + s + ".png", ImageFormat.Png);
                }
            }


        }


        public static Color RandomColor()

            return Color.FromArgb(r * 255, g * 255, b * 255);
        }

        public static GraphicsPath GraphicsPath(int px, int py, int pw, int ph)

            path.AddLines(new Point[]{

            });



            //path.AddArc(new Rectangle(new Point(rect.X, rect.Y), new Size(2 * cRadius, 2 * cRadius)), 180, 90);
            //path.AddLine(new Point(rect.X + cRadius, rect.Y), new Point(rect.Right - cRadius, rect.Y));
            //path.AddArc(new Rectangle(new Point(rect.Right - 2 * cRadius, rect.Y), new Size(2 * cRadius, 2 * cRadius)), 270, 90);
            //path.AddLine(new Point(rect.Right, rect.Y + cRadius), new Point(rect.Right, rect.Bottom - cRadius));
            //path.AddArc(new Rectangle(new Point(rect.Right - 2 * cRadius, rect.Bottom - 2 * cRadius), new Size(2 * cRadius, 2 * cRadius)), 0, 90);

            //path.AddArc(new Rectangle(new Point(rect.X, rect.Bottom - 2 * cRadius), new Size(2 * cRadius, 2 * cRadius)), 90, 90);

            path.CloseFigure();
            return path;
