Spire.Barcode for Java 5.1.11 现已发布。 在该版本中，BarcodeScanner 类新增了方法用于获取条码信息，扫描 Aztec 类型，以及使用更多重载设置进行扫描。此外，此次更新还包含了一些内部接口的调整。详情请查阅以下内容。

新功能:

• BarcodeScanner 类支持获取条码信息，包括类型、数据值和顶点位置信息。

BarcodeInfo[] infos = BarcodeScanner.scanInfo("barcode.png");
Point[] loaction = infos[0].getVertexes();
BarCodeReadType barCodeReadType = infos[0].getReadType();
String dataString =  infos[0].getDataString();

• BarcodeScanner 类支持扫描 Aztec 类型。

String[] s = BarcodeScanner.scan("AZTEC.png",BarCodeType.Aztec);

• BarcodeScanner 类支持使用更多重载设置进行扫描。

Public static String[] scan(BufferedImage bitmap, java.awt.Rectangle rect, BarCodeType barcodeType, boolean IncludeCheckSum)
Public static String[] scan(String fileName, BarCodeType barcodeType, boolean IncludeCheckSum)
Public static String scanOne(String fileName, BarCodeType barcodeType, boolean IncludeCheckSum)
Public static String scanOne(InputStream stream, BarCodeType barcodeType, boolean IncludeCheckSum)

• 新增外部使用枚举：

com.spire.barcode.publics.drawing.FontStyle
com.spire.barcode.publics.drawing.GraphicsUnit
com.spire.barcode.publics.drawing.StringAlignment

• IBarCodeSettings 接口变动
