本文主要是介绍C# 绘图及古诗填字,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!

绘图

绘图的结果如下:

绘图部分主要使用了 Bitmap、Graphics 

具体的函数是 MakeMap

入参说明

string bg : 背景图
Rectangle rect :绘图区域
int row_count :行数
int col_count :列数
string fn :保存到的文件

代码如下:

        public void MakeMap(string bg ,Rectangle rect ,int row_count,int col_count ,string fn){Bitmap bmp = new Bitmap(bg);Graphics g = Graphics.FromImage(bmp);           SHIUtils u = new SHIUtils();u.init_data(data);int line_w = 1;int cell_w = (rect.Width - line_w*(col_count+1)) / col_count;int cell_h = (rect.Height - line_w * (row_count + 1)) / row_count;int w = line_w * (col_count + 1) + cell_w * col_count;int h = line_w * (row_count + 1) + cell_h * row_count;int x0 = rect.X + (rect.Width - w) / 2;int y0 = rect.Y + (rect.Height - h ) / 2;Pen pen = new Pen(Color.FromArgb(196, 196, 196));for (int col = 0; col <= col_count; col++){int x = x0 + (line_w + cell_w) * col;g.DrawLine(pen, x, y0, x, y0 + h - line_w);}for (int row = 0; row <= row_count; row++){int y = y0 + (line_w + cell_h) * row;g.DrawLine(pen, x0, y, x0 + w - line_w, y);}// g.SmoothingMode = SmoothingMode.HighQuality;g.TextRenderingHint = TextRenderingHint.AntiAlias;Font font = new Font("汉呈波波浓墨行楷", cell_w*90/100, FontStyle.Regular);SolidBrush brush = new SolidBrush(Color.Black);SolidBrush brush_cell = new SolidBrush(Color.FromArgb(225, 225, 225));StringFormat sf = new StringFormat();SHIMap map = u.make_map(col_count, row_count);for (int col = 0; col < col_count; col++)for (int row = 0; row < row_count; row++){MapHole cell= map.map[col, row];if (cell.chr != ' '){int x = x0 + (line_w + cell_w) * col + line_w;int y = y0 + (line_w + cell_h) * row + line_w;g.FillRectangle(brush_cell, new Rectangle(x , y , cell_w  , cell_h));string s = cell.chr.ToString();if (cell.sentence_list.Count == 2)s = "?";sf.Alignment = StringAlignment.Center;sf.LineAlignment = StringAlignment.Center;g.DrawString(s, font, brush, new Rectangle(x, y, cell_w, cell_h), sf);} }            g.Dispose(); bmp.Save(fn, ImageFormat.Png);bmp.Dispose();}

 古诗填字

绘图的内容由SHIUtils生成。

SHIMap map = u.make_map(col_count, row_count);

 函数中使用了随机数,每次调用生成的内容都不一样,具体的代码如下:

 public class SHIUtils{public static Char Char_comma = ',';public static Char Char_period = '。';public static Char Char_period_1 = '!';public static Char Char_period_2 = '?';public static Char Char_period_3 = '、';public static Char Char_period_4 = ';';public static Char Char_period_5 = ':';public static Char Char_period_6 = '\r';public static Char Char_period_7 = '\n';public Random rd = new Random(Guid.NewGuid().GetHashCode());public void clear(){}private SHIData _data = null;private Dictionary<char, int> _char_dict = new Dictionary<char, int>();private Dictionary<int, SHI> _shi_dict = new Dictionary<int, SHI>();private Dictionary<int,  Sentence> _sentence_dict= new Dictionary<int, Sentence>();private Dictionary<char, Dictionary<int, Sentence>> _sentence_index = new Dictionary<char, Dictionary<int, Sentence>>();private Dictionary<char, List<Sentence>> _sentence_index_list = new Dictionary<char, List< Sentence>>();private Dictionary<int, Dictionary<int, Sentence>> _sentence_index_len = new Dictionary<int, Dictionary<int, Sentence>>();private Dictionary<int, List< Sentence>> _sentence_index_len_list = new Dictionary<int, List<Sentence>>();public Dictionary<int, List<Sentence>> get_sentence_index_len_list(){return _sentence_index_len_list;}public Dictionary<int, SHI> get_shi_dict(){return _shi_dict;}private void do_init(){clear();make_char_dict();make_sentence_list();}private void make_char_dict(){_char_dict.Clear();foreach (SHI i in _data.Items){foreach (Char ch in i.contson){if (_char_dict.ContainsKey(ch))continue;_char_dict[ch] = _char_dict.Count;}}}private void make_sentence_list(){_shi_dict.Clear();_sentence_dict.Clear();_sentence_index.Clear();_sentence_index_list.Clear();_sentence_index_len.Clear();_sentence_index_len_list.Clear();foreach (SHI i in _data.Items){_shi_dict[i.id] = i;Sentence s = null;int idx = 0;foreach (Char ch in i.contson){if (ch == '\r')continue;if (ch == '\n')continue;if (s == null){s = new Sentence();s.shi_id = i.id;s.idx = idx;s.id = s.shi_id * 1000 + idx;idx++;_sentence_dict[s.id]=s;}if ((ch == Char_comma) || (ch == Char_period) || (ch == Char_period_1) || (ch == Char_period_2) || (ch == Char_period_3) || (ch == Char_period_4)||(ch==Char_period_5) || (ch == Char_period_6) || (ch == Char_period_7)){s.chr_end = ch;foreach (Char ch_s in s.chrlist){Dictionary<int, Sentence> ls = null;if (!_sentence_index.TryGetValue(ch_s,out ls)){ls = new Dictionary<int, Sentence>();_sentence_index[ch_s] = ls;}if (!
