Using AQtime to profile a simple application I have found that I loose 8 bytes on every call that uses the Renderer. While this sounds like a small amount of memory.. trust me - it adds up. My application needs to run unattended for months, and it could process thousands of pages every day making several calls to the Renderer per page.

This is my sample code:

procedure TForm1.Button2Click(Sender: TObject);

var quickPDF : TiSEDQuickPDF;

begin

      quickPDF := TiSEDQuickPDF.Create;

      quickPDF.UnlockKey( MY_QDPF_KEY );

      quickPDF.LoadFromFile( 'AnyDocument.pdf' );

      try

            // This call uses renderer to get text details

            Memo1.Lines.Text := quickPDF.GetPageText( 3 );

      finally

            quickPDF.Free;

      end;

end;

I have found the offending section of code in uPDFRenderer.pas but I don’t know why this code is creating a leak.

This function is found at line 1355 of uPDFRenderer.pas

  procedure DrawXObject(const ResName: string);

Does anybody have any ideas or suggestions?

Thanks

Found it!

Unit:uPDFImageDecoder approx Line:1300

Change From :

procedure TPDFImageDecoder.SetColorManager(
NewColorManager: TPDFColorManager);
begin
  FColorManager := NewColorManager; // << This simply assigns a new object to the pointer for an old object that  can now no longer be freed.
  FPrivateColorManager := False;
end;

Change TO:

Dave,

If you can wait for Michel you may be better off.  The only DCU that I have is D7 and I am not well equiped to compile other versions at this time.

If D7 is what you need and you just can't wait, let me know and I will send you the DCU.

DCUs are version specific. If you are using D7 and you do not have source code you must have DCUs that were compiled with D7 the same will hold true for D2005 & D2006.

Supplying multiple versions of the DCUs for the group may prove to be a challenge. While I have several versions of Delphi, I don’t usually have more that one version installed at a time. Even though I bought it, I may never install D2005. I will probably just jump to D2006 when I finally get around to upgrading.
