Hello.

I have another pdf file. I want to change its content.

Sample code how I get the text:

var

i,j:integer;

str:string;

begin

j:= PDFLibrary.DAOpenFile('D:\32a0g.pdf','');

i:= PDFLibrary.DAExtractPageTextBlocks(j,PDFLibrary.DAFindPage(j,1),3);

str:= PDFLibrary.DAGetTextBlockText(i,2);

memo1.Text:= str;

end;

//************ RESULT STR = TEST **********//

how do i change the content of "PDFLibrary.DAGetTextBlockText (i, 2);" on "TSET"

ReplaceTag('TEST','TSET'); - does not work :(

Hi Muljtik,

there are still probs while subsetted fonts are used.
Here's a sample how to use the function:
https://www.debenu.com/kb/replace-text-pdf/
...

DPL.CombineContentStreams();
string content = DPL.GetContentStreamToString();
DPL.SetPageContentFromString(content.Replace("Moby", "Mary"));

Cheers and welcome here,
Ingo

      PDFLibrary.LoadFromFile('D:\a0g1.pdf','');
      i:=PDFLibrary.Decrypt;
      str:= inttostr(i);

     // PDFLibrary.CombineContentStreams();
    //   str:= PDFLibrary.GetContentStreamToString();

memo1.Text:= str;

//****************************//

Function Decrypt returns code 0....

0 could mean that the pdf isn't encrypted.
You should try a...
If PDFLibrary.EncryptionStatus > 0 Then
PDFLibrary.Decrypt;
...first.
