C# 绘图及古诗填字
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();

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_4 = '；';
public static Char Char_period_5 = '：';
public static Char Char_period_6 = '\r';
public static Char Char_period_7 = '
