Jim,

QPL has hundreds of functions and even ones I have need seen before. There is a QP.ReplaceTag function that searches for text within the content stream an replaces the text with a new value. This may or may not work as expected based on the complexity of the document including fonts and the uniqueness of the tag. Text will not be rewrapped and spacing of other text elements may or may not be affected.

QP.LoadFromFile("99pages.pdf", "");

QP.ReplaceText("Page 19", "Page 99") // This shouldn't cause too many problems.

QP.SaveToFile("out.pdf");

My code is working correctly with your PDF and is returning the 22pt font from both pages.

Is LoadFromFile returning 1 in your case ? Does QP.PageCount return 1 or 2 ? It should be 2 for your PDF. It could be a permissions problem. I suspect LoadFromFile is failing. By default QPL always has a single blank page allocated in memory it could be that is the reason nothing is being extracted.

You may then try string s= QP.GetPageText(7); MessageBox.Show(s); to make sure the text is actually being extracted.

Hi!

I have an Oracle Database with blob fields used to store some pdf files.

I am trying to use Debenu Quick PDF to read these PDF blobs from Oracle and save them into PDF files (C:\ folder).

I have the following Delphi 7 code:

procedure TForm1.Button3Click(Sender: TObject);
var i, DocumentID, OK: Integer;
    blob: TStream;
begin
// snipped some code used to open the object QryStream (TQuery type) and to create
// the QP object

         while not QryStream.Eof do
           begin
             Inc(i);
             blob := QryStream.CreateBlobStream(QryStream.FieldByName('Content'),bmRead);
             OK := QP.LoadFromStream(blob,'');
             if OK <> 0 then
               begin
                 DocumentID := QP.SelectedDocument();
                 QP.DASaveAsFile(DocumentID,'C:\File_' + IntToStr(i) + '.pdf');
               end
             else
                 ShowMessage('Error: ' + IntToStr(QP.LastErrorCode));
             QryStream.Next;
           end;
       end;

The code below:
OK := QP.LoadFromStream(blob,'');
gives an Access violation error at address XXXXXXX

What am I doing wrong here?
I really need to read these PDFs stores and to save them as files!

Thank you!
Henrique

My company is looking to license a PDF library for use in our product and I have been assigned the task of
evaluating different libraries to determine which we want to use.

We use the Lib version, my application
crashes on this line:

DEBENUPDFLIBRARYLIB0912_DllMain(GetModuleHandle(NULL), DLL_PROCESS_ATTACH, NULL);

This is the error we get:
Unhandled exception at 0x770407e4 in cadracad.exe: 0xC0000025: Windows cannot continue from this exception.

We are attempting to call this from our C code which is not built with Unicode support. We are using
Visual Studio 2008 compilers. Is it possible to do what we are attempting?

Thanks!

I am wondering what your final goal is ? Do you want to reduce file size ? remove transparency ?

What type of files are you working with ? Large artwork files ? Do you want to send it to a printer ?

Hi Jim!

There isn't a replace text function.

Changing the free text content isn't easy stuff for such a light weight library.

Tag data (like meta data) you can change easily.

Please have a look in the online reference...

Cheers, Ingo
