• No java bindings

NuGet packages available on the releases page and on www.nuget.org:

• Tabula

Differences with tabula-java

• Uses PdfPig, and not PdfBox.
• Coordinate system starts from the bottom left point (going up) of the page, and not from the top left point (going down).
• The NurminenDetectionAlgorithm is replaced by SimpleNurminenDetectionAlgorithm, because it requieres an image management library.
• Table results might be different because of the way PdfPig builds Letters bounding box.

Usage

Stream mode - BasicExtractionAlgorithm

using (PdfDocument document = PdfDocument.Open("doc.pdf", new ParsingOptions() { ClipPaths = true })) { ObjectExtractor oe = new ObjectExtractor(document); PageArea page = oe.Extract(1); // detect canditate table zones SimpleNurminenDetectionAlgorithm detector = new SimpleNurminenDetectionAlgorithm(); var regions = detector.Detect(page); IExtractionAlgorithm ea = new BasicExtractionAlgorithm(); List<Table> tables = ea.Extract(page.GetArea(regions[0].BoundingBox)); // take first candidate area var table = tables[0]; var rows = table.Rows; }
