Unable to extract text from non searchable PDF in groupdocs parser

Hello,

I am extracting text from my documents using below code,

private string ExtractTextAll(MemoryStream stream, bool formatted)
{
    stream.Seek(0, SeekOrigin.Begin);
    GroupDocs.Parser.ExtractorFactory factory = new GroupDocs.Parser.ExtractorFactory();
    GroupDocs.Parser.Extractors.Text.TextExtractor extractor = formatted
        ? factory.CreateFormattedTextExtractor(stream)
        : factory.CreateTextExtractor(stream);
    if (extractor == null)
    {
        return null;
    }
    try
    {
        return extractor.ExtractAll();
    }
    finally
    {
        extractor.Dispose();
    }
}

but there are some pdf’s which are non searchable and in those pdf the text is not getting extracted, non-text-searchable.pdf (68.8 KB)

I tried the same in groupdocs parser online but I am unable to extract text in online example either.

How can I extract text from groupdocs parser in non searchable PDF’s.

GroupDocs.Parser API supports the text extraction only from ‘text’ formats. It can’t extract a text from image (the sample PDF has the image instead of text). However, Parser has a special API to connect third-party OCR solutions to parse a text from an image. Please see details here - Using OCR.

Thank you for your response, but I have a question, If I am using a 3rd party tool for OCR, what is the need of using Parser api as I can extract text from using my 3rd party tool.

and if I am using groupdocs for my product, why should I buy a 3rd party tool for OCR?

GroupDocs.Parser API supports the text extraction only from ‘text’ formats. It can’t extract a text from image (the sample PDF has the image instead of text).

Is there any plan from the side of groupdocs to provide solution for text extraction from image or pdf’s which contains image?
