Can strikethrough text be excluded from the export results?
Overall, FineReader Engine API does not provide a way to completely ignore strikethrough text during recognition. However, the information on whether or not a certain text fragment is strikethrough is available via the ICharParams::IsStrikeout. A guide on how to access text properties via the API is available in the Developer's Guide article Guided Tour > Advanced Techniques > Working with Text.
It is also possible to disable detection of the strikethrough formatting using the IFontFormattingDetectionParams::DetectUnderlineStrikeout property, but the strikethrough text itself would still be included in the output.
