IronOCR for .NET 2026.11.130 de out. de 2026
Recursos
Updated internal dependencies.
Correções
Fixed an issue where page orientation detection could incorrectly identify an upright page as rotated when small vertical text, such as captions, outweighed larger body text. Confidence reporting now better indicates whether the detected orientation is reliable.
Fixed an issue where copied text from searchable PDFs could place each word on a separate line or merge adjacent words in some PDF viewers. Copied text now preserves normal word spacing and line structure.
Fixed an issue where ReadDocumentAdvanced could throw an exception while detecting tables in some multi-page scanned PDFs that contain no tables.
