Hi,

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;

QP.UnlockKey(DebenuKey);

QP.NewDocument();

Pages := QP.GetImagePageCount(DirTmp + 'scanner.tif');

if Pages = 0 then Pages := 1;

for nK := 1 to Pages do

begin

if nK > 1 then QP.NewPage();

Id := QP.AddImageFromFile(DirTmp + 'scanner.tif', nK);

QP.SelectImage(Id);

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.SetOrigin(1);

QP.DrawImage(0, 0, ImageWidthInPoints, ImageHeightInPoints);

end;

QP.SaveToFile(DirTmp + 'scanner.pdf');

QP.Free;

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,

Ingo
