打印系统开发(63)——C# 实现虚拟打印机 HP Color LaserJet 4500 （2） True Type Font字体显示

本来打算酸所有的PCL HPGL/2的都贴出来.后来发现这里重要的字体显示 TTF的数据显示就2000多行 10来个类了.所以把这个独立出来.另外我增加了一些字符对应和轮廓显示的方法.有兴趣的朋友可以单独去使用.

效果图

使用代码

    private Zgke.MyImage.ImageFile.ImageTTF m_TTF = new ImageTTF(@"C:/Windows/Fonts/FZYTK.TTF");private void Form2_Load(object sender, EventArgs e){m_TTF.FillDraw = false;m_TTF.Brush = Brushes.Red;}private void button1_Click(object sender, EventArgs e){if (textBox1.Text.Length > 0) pictureBox1.Image = m_TTF[textBox1.Text[0]];}

下面是我们在虚拟打印机里使用的方法 以后贴PCL HPGL时候不会在贴这个类.只要是ImageTTF的就是这个了.

        /// <summary>///暴露一个方法这个方法用来在PCL文件显示里使用      /// </summary>public void LoadImage(){//字符数据string _TextFontBytes = "000200010000007F00C0001B001F0000373727373737273737373707373737073707270737072707273727073737372708151C051B0A1C041C150E1416140E141D051C0A1D041E140E14161419160A170041000F0020000F0041004100410041000F0020000F00410041004150002000";byte[] _Bytes = new byte[_TextFontBytes.Length / 2];for (int i = 0; i != _Bytes.Length; i++){_Bytes[i] = Convert.ToByte(_TextFontBytes.Substring(i * 2, 2), 16);}//方法pictureBox1.Image = m_TTF.GetImageOfBytes(_Bytes);}
