原文?C#版二維碼生成器附皮膚下載

前言

　　本文所使用的二維碼生成代碼是谷歌開源的條形碼圖像處理庫完成的，c#版的代碼可去https://code.google.com/p/zxing/downloads/list下載壓縮包。

　　截止目前為止最新版本為2.2，提供以下編碼格式的支持：

• UPC-A and UPC-E
• EAN-8 and EAN-13
• Code 39
• Code 93
• Code 128
• QR Code
• ITF
• Codabar
• RSS-14 (all variants)
• Data Matrix
• PDF 417 ('alpha' quality)
• Aztec ('alpha' quality)

　同時官網提供了 Android、cpp、C#、iPhone、j2me、j2se、jruby、objc、rim、symbian等多種應用的類庫，具體詳情可以參考下載的源碼包中。

　　本文已經下載好了，c#版的zxing代碼，并編譯生成了類庫，供程序直接調用。

軟件截圖及說明

功能說明：1、根據文字輸入及時生成二維碼，支持保存，打印

　　　　　2、支持解碼，打開二維碼文件解碼

　　　　　3、采用IrisSkin4皮膚美化

代碼說明

public MainForm()
{
InitializeComponent();
this.skinEngine1.SkinFile = Application.StartupPath + "//skins//SportsGreen.ssk";
this.p1.Visible = true;
//this.p2.Visible = false;

//用于實現PictureBox的鼠標移動過去的提示
ToolTip toolTip = new ToolTip();
toolTip.AutoPopDelay = 5000;//一下4個都是屬性
toolTip.InitialDelay = 1000;
toolTip.ReshowDelay = 500;
toolTip.ShowAlways = true;
toolTip.SetToolTip(this.open, "打開");//參數1是button名,參數2是要顯示的內容
toolTip.SetToolTip(this.save, "保存");
toolTip.SetToolTip(this.print,"打印二維碼");
toolTip.SetToolTip(this.decod,"解碼");
toolTip.SetToolTip(this.exit,"返回生成二維碼");
}?

　　主窗體顯示，皮膚，按鈕圖表鼠標移動顯示提示等代碼。

//隨文本框輸入內容生成二維碼圖片
private void txtContent_TextChanged(object sender, EventArgs e)
{
string content = txtContent.Text;
if (content == "")
{
MessageBox.Show("請輸入內容", "警告", MessageBoxButtons.OK, MessageBoxIcon.Error);
return;
}
ByteMatrix byteMatrix = new MultiFormatWriter().encode(content, BarcodeFormat.QR_CODE, 200, 200);
Bitmap bitmap = toBitmap(byteMatrix);
orpic.Image = bitmap;

}
//生成圖片代碼
public static Bitmap toBitmap(ByteMatrix matrix)
{
int width = matrix.Width;
int height = matrix.Height;
Bitmap bmap = new Bitmap(width, height, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
for (int x = 0; x < width; x++)
{
for (int y = 0; y < height; y++)
{
bmap.SetPixel(x, y, matrix.get_Renamed(x, y) != -1 ? ColorTranslator.FromHtml("0xFF000000") : ColorTranslator.FromHtml("0xFFFFFFFF"));
}
}
return bmap;
}
//時間顯示代碼
private void timer_Tick(object sender, EventArgs e)
{
this.timeshowlable.Text = DateTime.Now.ToString();
}

　　隨文本框輸入內容生成二維碼圖片及時間顯示代碼。

}

private void decod_MouseLeave(object sender, EventArgs e)
{
System.Drawing.Bitmap map = new Bitmap(Application.StartupPath + @"\image\encoding.png");
this.decod.Image = map;
}

　　鼠標移動到按鈕圖片，圖片切換代碼。

　　打開，保存，面板切換代碼。

private void print_Click(object sender, EventArgs e)
{
PrintDialog printDialog = new PrintDialog();
printDialog.Document = printDocument;
if (printDialog.ShowDialog() == DialogResult.OK) { try
{
printDocument.Print();
}
catch
{ //停止打印
printDocument.PrintController.OnEndPrint(printDocument, new System.Drawing.Printing.PrintEventArgs());
}
}
}

private void printDocument_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
{
if (this.p1.Visible == true)
{
e.Graphics.DrawImage(this.orpic.Image, 20, 20);
}
else
{
e.Graphics.DrawImage(this.picOpenQr.Image, 20, 20);
}
}

　　打印代碼。

關鍵代碼在txtContent_TextChanged()及打開方法中處理了。

最后說明：程序比較簡單，不做過多說明，時間倉促代碼存在很多不合理的地方，歡迎拍磚。
