Simplified example from my application:
var text = “1”;
var pdfDoc = new Document(“cs_10.pdf”);
var textAbsorber = new TextFragmentAbsorber($"(?i){text}", new TextSearchOptions(true));
pdfDoc.Pages.Accept(textAbsorber);Console.WriteLine(textAbsorber.TextFragments.Count);
Error:
Unhandled exception: System.ArgumentOutOfRangeException: Index is out of range. The index must be a positive number, and its size should not exceed the size of the collection.
Parameter name: startIndex
