超時
TimeoutMs提供了一個可選的超時時間（以毫秒為單位），超過該時間後，OCR讀取操作將被取消。
與 AbortToken 類似，TimeoutMS 在程序或應用程序運行時遇到卡住的情況下，也有助於讀取大型輸入文件。
請注意，該功能不支持在 .NET Framework 4.x.x 中。
using IronOcr;
int cancel_time = 1000;
// Opens a Large PDF which may need to be cancelled early
IronTesseract ocrTesseract = new IronTesseract() { Language = OcrLanguage.English };
var ocrInput = new OcrInput();
ocrInput.LoadPdf("large-report.pdf");
// Starts a read on the PDF using IronOCR with specified cancel time
OcrReadTask ocrRead = ocrTesseract.ReadAsync(ocrInput, cancel_time);
ocrRead.Wait();Imports IronOcr
