用C#实现一个字模点阵提取程序
本文源代码位于：http://download.csdn.net/detail/caozhy/4401532
程序比较简单，已经给出了主要源代码，十分希望对程序感兴趣的同学自己动手编译调试。实在懒得动脑动手的再去下载。故而设置了10分下载分。
上大学的时候搞单片机实验，大家都知道要提取字库。
很多人还在研究UCDOS下的那些点阵文件，其实使用C#，可以很方便地写一个程序提取Windows字体。
优点是，代码实现起来非常容易。并且可以借助Windows上庞大的TTF字体资源，实现各种各样的字体，不再局限UCDOS中几种有限的字体。还可以实现很多特殊效果，因为Windows的字体就是绘图嘛。
以前用VB写过一个，写了好久才写成。最近有人问，给了他思路，他却还是搞不定，我就很郁闷了，这个很难么？
自己写了下，几行代码就出来了。主要是LINQ实在太简洁了，没办法。
代码如下：
private void button3_Click(object sender, EventArgs e){ //显示按钮 var data = textBox2.Text.Select(x => x == '1').Concat(Enumerable.Repeat(false, 256)) .Take(256).ToArray(); Graphics g = pictureBox1.CreateGraphics(); for (int i = 0; i < 16; i++) { for (int j = 0; j < 16; j++) { Brush brush = data[j * 16 + i] ? Brushes.Blue : Brushes.White; g.FillRectangle(brush, new Rectangle() { X = i * 16, Y = j * 16, Width = 16, Height = 16 }); } }}private void button1_Click(object sender, EventArgs e){ //字体设置 FontDialog fd = new FontDialog() { Font = textBox1.Font, FontMustExist = true }; if (fd.ShowDialog() == System.Windows.Forms.DialogResult.OK) { textBox1.Font = fd.Font; }}private void button2_Click(object sender, EventArgs e){ //产生字模 Bitmap bmp = new Bitmap(16, 16); Graphics g = Graphics.FromImage(bmp); g.FillRectangle(Brushes.White, new Rectangle() { X = 0, Y = 0, Height = 16, Width = 16 }); g.DrawString(textBox1.Text, textBox1.Font, Brushes.Black, new PointF() { X = Convert.ToSingle(domainUpDown1.Text), Y = Convert.ToSingle(domainUpDown2.Text) }); textBox2.Text = string.Join("", Enumerable.Range(0, 256).Select(a => new { x = a % 16, y = a / 16 }) .Select(x => bmp.GetPixel(x.x, x.y).GetBrightness() > 0.5f ? "0" : "1")); button3.PerformClick();}private void textBox1_TextChanged(object sender, EventArgs e){ //输入文字的文本框 textBox1.Text = textBox1.Text.Length > 0 ? textBox1.Text.Substring(textBox1.Text.Length - 1) : ""; textBox1.SelectionStart = textBox1.Text.Length;}private void domainUpDown1_SelectedItemChanged(object sender, EventArgs e){ //微调，用来设置偏移 button2.PerformClick();}private void domainUpDown2_SelectedItemChanged(object sender, EventArgs e){ button2.PerformClick();}// 修改字体private void button1_Click(object sender, EventArgs e){ if (fontDialog1.ShowDialog() == DialogResult.OK) textBox1.Font = fontDialog1.Font;}// 生成字模private void button2_Click(object sender, EventArgs e){ if (string.IsNullOrEmpty(textBox1.Text)) return; Bitmap bmp = new Bitmap(16, 16); Graphics g = Graphics.FromImage(bmp); //g.FillRectangle(Brushes.White, new Rectangle() { X = 0, Y = 0, Height = 16, Width = 16 }); g.Clear(Color.White); //g.DrawString(textBox1.Text, textBox1.Font, Brushes.Black, new PointF() { X = Convert.ToSingle(domainUpDown1.Text), Y = Convert.ToSingle(domainUpDown2.Text) }); g.DrawString(textBox1.Text, textBox1.Font, Brushes.Black, (float)numericUpDown1.Value, (float)numericUpDown2.Value); //textBox2.Text = string.Join("", Enumerable.Range(0, 256).Select(a => new { x = a % 16, y = a / 16 }).Select(x => bmp.GetPixel(x.x, x.y).GetBrightness() > 0.5f ? "0" : "1")); StringBuilder sb = new StringBuilder(); for (int y = 0; y < 16; y++) { for (int x = 0; x < 16; x++) { if (bmp.GetPixel(x, y).GetBrightness() > 0.5f) sb.Append("0"); else sb.Append("1"); } } textBox2.Text = sb.ToString(); button3.PerformClick();}// 显示private void button3_Click(object sender, EventArgs e){ //var data = textBox2.Text.Select(x => x == '1').Concat(Enumerable.Repeat(false, 256)).Take(256).ToArray(); bool[] data = new bool[256]; for (int i = 0; i < 256; i++) { data[i] = textBox2.Text[i] == '1'; } Graphics g = pictureBox1.CreateGraphics(); for (int i = 0; i < 16; i++) { for (int j = 0; j < 16; j++) { Brush brush = data[j * 16 + i] ? Brushes.Blue : Brushes.White; //g.FillRectangle(brush, new Rectangle() { X = i * 16, Y = j * 16, Width = 16, Height = 16 }); g.FillRectangle(brush, i * 16, j * 16, 16, 16); } }}
[解决办法]
你好，运行了下，在显示字模的消息中有错，是string.Join的错误，它的第二个参数是string[]。但是源码中是string。求指教。
