zxing是谷歌開源的二維碼庫，zbar，thoughtworkQRcode也是開源的，三者之間比較各有優(yōu)劣，本文將通過一個(gè)案例demo源碼，帶來認(rèn)識(shí)學(xué)習(xí)下這三者的實(shí)際解碼效果，感興趣的可以了解一下

最近做項(xiàng)目需要解析二維碼圖片，找了一大圈，發(fā)現(xiàn)沒有人去整理下開源的幾個(gè)庫案例，花了點(diǎn)時(shí)間

做了zxing，zbar和thoughtworkqrcode解析二維碼案例，希望大家有幫助。

下面通過一個(gè)案例demo源碼，來認(rèn)識(shí)學(xué)習(xí)下這三者的實(shí)際解碼效果，

第一次上傳demo源碼，獻(xiàn)丑了

zbar解析關(guān)鍵代碼：

Image primaryImage = Image.FromFile(fileName);
Bitmap pImg = MakeGrayscale3((Bitmap)primaryImage);
using (ZBar.ImageScanner scanner = new ZBar.ImageScanner())
{
    List<ZBar.Symbol> symbols = new List<ZBar.Symbol>();
    System.Diagnostics.Stopwatch watch = new Stopwatch();
    watch.Start();
    symbols = scanner.Scan((Image)pImg);
    watch.Stop();
    TimeSpan timeSpan = watch.Elapsed;
    MessageBox.Show("掃描執(zhí)行時(shí)間：" + timeSpan.TotalMilliseconds.ToString());
    if (symbols != null && symbols.Count > 0)
    {
        string result = string.Empty;
        symbols.ForEach(s => result += "條碼內(nèi)容:" + s.Data + " 條碼質(zhì)量:" + s.Type + Environment.NewLine);
        MessageBox.Show(result);
    }
}

zxing解析關(guān)鍵代碼：

Image primaryImage = Image.FromFile(fileName);
Bitmap pImg = MakeGrayscale3((Bitmap)primaryImage);
BarcodeReader reader = new BarcodeReader();
System.Diagnostics.Stopwatch watch = new Stopwatch();
watch.Start();
Result result = reader.Decode((Bitmap)pImg); //通過reader解碼
watch.Stop();
TimeSpan timeSpan = watch.Elapsed;
MessageBox.Show("二維碼值："+result+"掃描執(zhí)行時(shí)間：" + timeSpan.TotalMilliseconds.ToString());

thoughtworkqrcode解析關(guān)鍵代碼：

Image primaryImage = Image.FromFile(fileName);
Bitmap pImg = (Bitmap)primaryImage;// MakeGrayscale3((Bitmap)primaryImage);
try
{
    System.Diagnostics.Stopwatch watch = new Stopwatch();
    watch.Start();
    string decodedString = new QRCodeDecoder().decode(new QRCodeBitmapImage(pImg), Encoding.UTF8);
    watch.Stop();
    TimeSpan timeSpan = watch.Elapsed;
    MessageBox.Show("二維碼值：" + decodedString + "掃描執(zhí)行時(shí)間：" + timeSpan.TotalMilliseconds.ToString());
}
catch (Exception ex)
{
    MessageBox.Show("好難過");
}

下面來測(cè)試下三者之間的給力程度吧，在草料二維碼網(wǎng)頁上在線生成一個(gè)二維碼
