    I am using the GcPdfDocument.FindText method with a regular expression search parameter. This method correctly finds matching text, but the result doesn’t seem to include a property that shows the text that was actually matched. It has a NearText property, but it includes additional text “near” the found text (hence the name NearText, I guess). Is the exact matched text intentionally not returned for some reason? I guess I could use the .NET regex function on the NearText property to extract the exact text, but that feels like an unneccessary step. Am I missing something? Thanks.

    After looking around a little more, I see the TextMapFragment property that appears to show the positions of the matched text within the NearText property, but it doesn’t always seem to be the correct positions. I have attached a small project that hopefully demonstrates the issue.

    The requirement is not clear to the developers with your given comments. They have modified the sample, and PositionInNearText has correct value, please go through it and let me know if it works.

    Ok, so to extract the found text, I would need to do

    text.NearText.Substring(text.PositionInNearText, text.TextMapFragment[0].Length)

    It seems confusing to me that FoundPosition has a property for the start position, but not the length (I have to go into the TextMapFragment to get the length). Anyway, thanks for the help.
