I am user of 11.12 version and I generated a lot of PDF using the simple code below.  By the way, some documents was stoled and now I need identify who was generated by Debenu to try a proof that is original. If part of License Key or any other tag is found, I can to proof that document was generated by Debenu or by me.

Thaks a lot for any information.

QP := TDebenuPDFLibrary.Create;
Pages := QP.GetImagePageCount(DirTmp + 'scanner.tif');
if Pages = 0 then Pages := 1;
for nK := 1 to Pages do
    if nK > 1 then QP.NewPage();
    Id := QP.AddImageFromFile(DirTmp + 'scanner.tif', nK);
    Dpix := QP.ImageHorizontalResolution();
    Dpiy := QP.ImageVerticalResolution();

    if Dpix = 0 then Dpix := 200;
    if Dpiy = 0 then Dpiy := 200;

    ImageWidthInPoints := 792;
    ImageHeightInPoints := 1145;

    QP.SetPageDimensions(ImageWidthInPoints, ImageHeightInPoints);
    QP.DrawImage(0, 0, ImageWidthInPoints, ImageHeightInPoints);
QP.SaveToFile(DirTmp + 'scanner.pdf');

Hi Zadoque,

if you read in the pdf-file as a string or stream you can check fulltext for the strings:
"/QuickPDF" and/or "/iSQP" (without the quotes).
If one of them is inside it's a pdf made by QuickPDF.

Cheers and welcome here,
