該文主要是利用OnBarcode.dll 生成 DataMatrix 格式的二維碼的一些簡單方法和操做技巧。關於QrBarcode的二維碼比較常見和簡單,網上有不少資源。函數
一、附件爲dll測試
二、利用上述控件生成二維碼的核心代碼:this
(a)C# 代碼:編碼
DataMatrix datamatrix = new DataMatrix();
datamatrix.Data = "0123456789";
// Create Data Matrix and encode barcode to Jpeg format
datamatrix.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg;
datamatrix.drawBarcode("C://csharp-datamatrix.jpg");
(b) VB.NET 代碼:spa
Dim datamatrix As OnBarcode.Barcode.DataMatrix
datamatrix = New OnBarcode.Barcode.DataMatrix()
datamatrix.Data = "0123456789"
' Create Data Matrix and encode barcode to Jpeg format
datamatrix.ImageFormat = System.Drawing.Imaging.ImageFormat.Jpeg
datamatrix.drawBarcode("C://vbnet-datamatrix.jpg")
(c)其餘函數接口(分別是C#和VB):code
public void drawBarcode(Graphics graphics);
public void drawBarcode(string filename);
public Bitmap drawBarcode();
public void drawBarcode(Stream fileStream);
Public Sub drawBarcode(ByRef graphics As Graphics)
Public Sub drawBarcode(ByVal filename As String)
Public Function drawBarcode() As Bitmap
Public Sub drawBarcode(ByRef fileStream As Stream)
三、實踐部分:orm
建立以下界面:按鈕按下,生產條碼。blog
using System;接口
using System.Collections.Generic;圖片
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using OnBarcode.Barcode;
using System.Drawing.Imaging;
namespace DataMatrix1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
DataMatrix datamatrix = new DataMatrix();
// Barcode data to encode
datamatrix.Data = "OnBarcode";
// Data Matrix data mode
datamatrix.DataMode = DataMatrixDataMode.ASCII;
// Data Matrix format mode
datamatrix.FormatMode = DataMatrixFormatMode.Format_10X10;
/*
* Barcode Image Related Settings
*/
// Unit of meature for all size related setting in the library.
datamatrix.UOM = UnitOfMeasure.PIXEL;
// Bar module size (X), default is 3 pixel;
datamatrix.X = 3;
// Barcode image left, right, top, bottom margins. Defaults are 0.
datamatrix.LeftMargin = 0;
datamatrix.RightMargin = 0;
datamatrix.TopMargin = 0;
datamatrix.BottomMargin = 0;
// Image resolution in dpi, default is 72 dpi.
datamatrix.Resolution = 72;
// Created barcode orientation.
// Rotate0 = 0,
// Rotate90 = 1,
// Rotate180 = 2,
// Rotate270 = 3,
// 4 options are: facing left, facing right, facing bottom, and facing top
datamatrix.Rotate = Rotate.Rotate0;
// Geneat data matrix and encode barcode to gif format
datamatrix.ImageFormat = System.Drawing.Imaging.ImageFormat.Bmp;
datamatrix.drawBarcode("C:\\datamatrix.jpg"); //以保存特定格式方法生產二維碼
//You can also call other drawing methods to generate barcodes
//public void drawBarcode(Graphics graphics);
//public void drawBarcode(string filename);
//public Bitmap drawBarcode();
//public void drawBarcode(Stream stream); //將該種編碼的格式,寫入文件流之中
this.pictureBox1.Image = datamatrix.drawBarcode(); //調用其中一個接口,將圖片以bitmap形式顯示出來
}
}
}
測試結果:
當初只是隨便分享一下,沒想到你們使用條碼的這麼多,評論也有不少,謝謝你們支持。
這裏附上幾個條碼經常使用的dll。
可在這裏下載:https://i.cnblogs.com/Files.aspx
事實上:生成條碼的方法有不少種,庫也有不少,你們能夠多去琢磨琢磨,不能侷限一種,就我所知所用過的就有五個庫。
網上也有不少對條碼底層的開源研究,可自行。
分享共進步,謝謝閱讀!
