条形码快速入门
IronBarCode 支持多种标准格式,从图像文件(jpeg、png 和 jpg)到更适合程序化操作的格式(例如位图),后者允许在程序中传递变量。此外,它还支持 PDF 等外部格式,使 IronBarCode 能够无缝集成到任何代码库中,并为开发人员提供处理文件格式和变量的灵活性。
IronBarCode 允许开发人员扫描标准文件格式的条形码。 然而,在某些情况下,开发人员希望微调 Read 方法的行为,尤其是在以编程方式读取一批条形码文件的情况下。 This is where BarcodeReaderOptions comes in. IronBarCode lets you fully customize things such as the speed at which it reads with Speed, whether multiple barcodes are expected in the file with ExpectedMultipleBarcodes, and what kind of barcodes they are with the property ExpectBarcodeTypes. 该工具允许开发人员运行多个线程并行读取多个图像中的 BarCode,还可以控制并行读取时使用的线程数量。
