Extract PDF text by coordinates

Question

I\'d like to know if there\'s some PDF library in Microsoft .NET being able of extracting text by giving coordinates.

For example (in pseudo-code):

<         


        

Answer 1

This should work:

RenderFilter[] filters = new RenderFilter[1];
LocationTextExtractionStrategy regionFilter = new LocationTextExtractionStrategy();
filters[0] = new RegionTextRenderFilter(new Rectangle(llx,lly,urx,ury));
FilteredTextRenderListener strategy = new FilteredTextRenderListener(regionFilter, filters);

String result = PdfTextExtractor.GetTextFromPage(pdfReader, i, strategy);
Console.WriteLine(result);
