   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
	Cheers, Ingo

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