Extract Text from PDF Document via .NET Library

PDF.Extractor for .NET supports three types of operating mode:

1. Pure gives the possibility to extrat the text from the PDF file using several formatting procedures, which include taking into account relative positions and adding extra spaces align text to the width of the page.

2. Raw extracts text the PDF file without formatting it.

3. Plain extracts text from the PDF file considering relative positioning of the text fragments but (unlike the Pure Mode) without adding extra space.

If the mode isn't set by developer the default mode is 'Raw'

Sample code for extracting text with 'default' options:

{
    PdfTextExtractionOptions extractorOptions = new PdfTextExtractionOptions();
    extractorOptions.AddDataSource(new FileDataSource(dataDir + "input.pdf"));
    ResultContainer resultContainer = extractor.Process(extractorOptions);
    string textExtracted = resultContainer.ResultCollection[0].ToString();
    Console.WriteLine(textExtracted);
}

{
    PdfTextExtractionOptions extractorOptions = new PdfTextExtractionOptions(PdfTextExtractionOptions.TextFormattingMode.Pure);
    extractorOptions.AddDataSource(new FileDataSource(dataDir + "input.pdf"));
    ResultContainer resultContainer = extractor.Process(extractorOptions);
    string textExtracted = resultContainer.ResultCollection[0].ToString();
    Console.WriteLine(textExtracted);
}

Multiple input files (or streams) can be specified as input. Then the ResultCollection will contain the corresponding number of results. Example:

    GetInputPath(dataDir + "text_sample2.pdf")
};
using (PdfExtractor extractor = new PdfExtractor())
{
    PdfTextExtractionOptions extractorOptions = new PdfTextExtractionOptions(PdfTextExtractionOptions.TextFormattingMode.Pure);
    foreach (string inputPath in inputPaths)
    {
        extractorOptions.AddDataSource(new FileDataSource(inputPath));
    }
    ResultContainer resultContainer = extractor.Process(extractorOptions);
    for (int i = 0; i < resultContainer.ResultCollection.Count; i++)
    {
        string textExtracted = resultContainer.ResultCollection[i].ToString();
        Console.WriteLine(textExtracted);
    }
