设置条码读取选项
IronBarcode 在 BarcodeReaderOptions 类中有多种选项来支持定制和优化的读取。 您可以设置它以消耗更多资源以获得更准确的读取,设置在找到一个条形码后停止或读取所有条形码,缩小要检测的条形码类型范围,聚焦一个裁剪区域,并限制并行线程的数量。
using IronBarCode;
BarcodeReaderOptions myOptionsExample = new BarcodeReaderOptions()
{
// Choose a reading speed from: Faster, Balanced, Detailed, ExtremeDetail
// There is a tradeoff in performance as more detail is set
Speed = ReadingSpeed.Balanced,
// Reader will stop scanning once a single barcode is found (if set to true)
ExpectMultipleBarcodes = true,
// By default, all barcode formats are scanned for
// Specifying a subset of barcode types to search for would improve performance
ExpectBarcodeTypes = BarcodeEncoding.AllOneDimensional,
// Utilize multiple threads to read barcodes from multiple images in parallel
Multithreaded = true,
// Maximum threads for parallelized barcode reading
// Default is 4
MaxParallelThreads = 2,
// The area of each image frame in which to scan for barcodes
// Specifying a crop area will significantly improve performance and avoid noisy parts of the image
CropArea = new System.Drawing.Rectangle(),
// Special setting for Code39 barcodes
// If a Code39 barcode is detected, try to read with both the base and extended ASCII character sets
UseCode39ExtendedMode = true
