With many modern PDF files options 0, 1, 2 don't extract text from some complex PDF's.  Option 8 is an improved version of option 0.  Options 3,4,5,6,7 use the improved extraction logic.

I only want to know if the word "blah" appears in the PDF file. I understand that I can't do this with image only PDF files ... that is okay. Thus I load all the strings into a buffer and then I'll search myself for "blah".

sTxt += QP.DAExtractPageText(FH, PR, 0);

0 should be the fastest.
If 0 is useful for you depends on what you wanna do with the text.

Thank you for your help. I'm testing the sample function below. Is this the fastest way? I just want to make sure I'm doing all I can. Also, I don't understand DASetTextExtractionOptions ... should I use it to optimize anything?



Quote
size_t GetText_PDF(std::wstring & sF, std::wstring & sTxt)
{
     int FH, PR, iPages;

    // Open file readonly
    FH = QP.DAOpenFileReadOnly(sF, L"");
    if(FH == 0){return FILE_ERROR_OPEN;}

    // Get page count
    iPages = QP.DAGetPageCount(FH);

    // loop over pages
    for(int i = 1; i <= iPages; i++)
    {
        // Get a page reference to the current page
        PR = QP.DAFindPage(FH, i);

        // Extract the text from the current page
        sTxt += QP.DAExtractPageText(FH, PR, 8);
    }

     // Close file
     QP.DACloseFile(FH);

     return FILE_SUCCESS;
}

Hi!

This library offers over 500 functions for a low price.
Textextraction was already in the first versions many years ago.
So this should be stable but it won't be optimized specially for
textextraction.
Personal opinions will be different so you have to try.

Cheers, Ingo

Well, yes I've read some of the materials. I'm looking at about 5 different solutions and wanted my hand held a little :)

I know how to use you're library, just wanted a fuzzy feeling that it is up to the task for my requirements. Some PDF libraries are more for creation or editing ... I just want the text as fast as I can. Is QuickPDF optimized for this?

P.S.
I did not find it referenced anywhere, but can the .LIB version work with C++ Builder 2007 or is that for only Visual Studio? The .DLL version is fine, just wondering.

So you didn't read the documents from the original support pages of the publishers ;-)

Hi!

The searching could be done with your programming language
and the textextraction could be done with QuickPDF with several
kinds of options.
Your performance-question: It always depends on ... Try it ;-)

I am evaluating the QuickPDF library (.dll version) for use in a C++ application. The only functionally I need it to extract the text. The entire PDF's text will be placed in memory and then I'll search for keyword terms.

Is QuickPDF suitable for this type of work and offer good performance?
