# camelot-sharp

A C# library to extract tabular data from PDFs (port of camelot Python version using PdfPig).

Original Python source code available here: [camelot-dev/camelot](https://github.com/camelot-dev/camelot).

[![Windows](https://github.com/BobLd/camelot-sharp/actions/workflows/dotnet.yml/badge.svg)](https://github.com/BobLd/camelot-sharp/actions/workflows/dotnet.yml)

NuGet packages available on the [releases](https://github.com/BobLd/camelot-sharp/releases) page and on www.nuget.org:

- [Camelot](https://www.nuget.org/packages/Camelot)

- [Camelot.ImageProcessing.OpenCvSharp4](https://www.nuget.org/packages/Camelot.ImageProcessing.OpenCvSharp4)

# Usage

## Stream mode 

```csharp

using (PdfDocument doc = PdfDocument.Open(@"Files\foo.pdf", new ParsingOptions() { ClipPaths = true }))

{

	Stream stream = new Stream();

	var tables = stream.ExtractTables(doc.GetPage(1));

	Assert.Single(tables);

	Assert.Equal((612, 792), stream.Dimensions);

	Assert.Equal(612, stream.PdfWidth);

	Assert.Equal(792, stream.PdfHeight);

	//Assert.Equal(84, stream.HorizontalText.Count);

	var parsingReport = tables[0].ParsingReport();

	//   parsing_report = {"accuracy": 99.02, "whitespace": 12.24, "order": 1, "page": 1}

	parsingReport["order"] = 1;

	parsingReport["page"] = 1;

}

```

## Lattice mode

```csharp

using (var doc = PdfDocument.Open(@"Files\column_span_2.pdf", new ParsingOptions() { ClipPaths = true }))

{

	var page = doc.GetPage(1);

	Lattice lattice = new Lattice(new OpenCvImageProcesser(), new BasicSystemDrawingProcessor(), line_scale: 40);

	var tables = lattice.ExtractTables(page,

		layout_kwargs: new DlaOptions[]

		{

			new DocstrumBoundingBoxes.DocstrumBoundingBoxesOptions()

			{

				WithinLineMultiplier = 2

			}

		});

	Assert.Single(tables);

	Assert.Equal(DataLatticeShiftTextLeftTop.Length, tables[0].Cells.Count);

	Assert.Equal(DataLatticeShiftTextLeftTop, tables[0].Data().Select(r => r.Select(c => c).ToArray()).ToArray());

}

```
