How to remove "Pdf author" ?

[g.politi]

Hi,

maybe "Pdf author" is not the right translation (I'm using an italian version of the Acrobat reader) but looking at the advance property I see that the Pdf Author of the Pdf is "PDF-XChange (xcpro40.dll v4.0.0185.0000)".

Is possible to change it with another string ?

Best regards

G

Hello g.politi,

The term in English is "PDF Producer"

And using "PXC_SetDocumentInfoA"

you can set the "InfoField_Producer"

There is also an Author Field - which you can control in the very same way - please refer to section 2.1.9 of the PDF Tools SDK Manual.

Best,
Stefan

Thanks for the quick reply .... I already tried to use the way you explained but seems it doesn't work ....

Here the code used (Delphi 2009)

dwResult:=PXCp_SetDocumentInfoExW(hDoc,PWChar('InfoField_Author'),PWChar('test'));
if IS_DS_ERROR(dwResult) then
begin
PXCp_Delete(hMergeDoc);
exit;
end;
dwResult:=PXCp_SetDocumentInfoExW(hDoc,PWChar('InfoField_Creator'),PWChar('test'));
if IS_DS_ERROR(dwResult) then
begin
PXCp_Delete(hMergeDoc);
exit;
end;
dwResult:=PXCp_SetDocumentInfoExW(hDoc,PWChar('InfoField_Producer'),PWChar('test'));
if IS_DS_ERROR(dwResult) then
begin
PXCp_Delete(hMergeDoc);
exit;
end;


dwResult := PXCp_WriteDocumentW(hDoc, PWChar(WideString(sFileNameDest)), PXCp_CreationDisposition_Overwrite, PXCp_Write_NoRelease);
PXCp_Delete(hDoc);


Best regards

NOTE: I also tried using dwResult := PXCp_SetDocumentInfoW(hDoc, InfoField_Producer, PWChar('test')); without any luck ...

Hello g.politi,

The PXCp_SetDocumentInfoEx(A/W) functions are for storing additional information, while the
PXCp_SetDocumentInfo(A/W) are for storing standard information - all possible standard Fields are:

Code: Select all

InfoField_Title        Sets the Title field in the info structure of the pdf file.
InfoField_Subject      Sets the Subject field in the info structure of the pdf file.
InfoField_Author       Sets the Author field in the info structure of the pdf file.
InfoField_Keywords     Sets the Keywords field in the info structure of the pdf file.
InfoField_Creator      Sets the Creator field in the info structure of the pdf file.
InfoField_Producer     Sets the Producer field in the info structure of the pdf file.

So please use the SetDocumentInfo functions for those.

Best,
Stefan

Hi Stefan,

I did it without any luck .... I used:

dwResult := PXCp_SetDocumentInfoW(hDoc, InfoField_Producer, PWChar('test'));

is this correct ?

the program flow is : open a Pdf, use PXCp_SetDocumentInfoW and save the PDF

What I'm doing wrong ?

Thanks for the support

Hello Giovanni,

After speaking with the dev guys they told me that this particular field is rewritten by xcpro40.dll, and it is done so intentionally, so I am afraid that this one field you can not control

Sorry guys, but this is not fair play! Because (1) we have paid much money for the Pro version of PDF-Tools SDK and (2) our competitors they not use tracker-components can also create PDF's with own producer-tag and (3) also in your documentation we can read, that "producer" can be change.

SO PLEASE ALLOW THIS VERY IMPORTANT META-TAG. Because our application does not appears professional!

BTW: I have also tried to set AllowSaveCustomProducer and rewrite the producer by the viewer. But also without success!
Please tell us a way/workaround to write the producer.

As stated - this is not possible and will not be possible.

If you are trying to hide the fact you utilise our libraries/products from the outside world - then how do you propose to avoid stating in your documentation etc that you are doing so - which is a requirement of your licensing our tools ?

Sad, but I will bow to this pressure.

Thanks for the understanding Dorwol!
