Hello.

Yes sure.

I will attach the file, and the code is as follows:

PdfContentEditor ced = new PdfContentEditor();

ced.BindPdf(@"\the\file\path\test1.pdf");

ced.ReplaceText("<<APR1>>", "ABC12345");

ced.Save(@"\the\file\path\test1_out.pdf");

Thats all. And also i have tryed to optimised the input pdf for lower versions of pdf formats ,but the problem is still there.

But I noticed that the output pdf get broken only when a replacement is about to be done. I mean, when I enter some matching string that I know it exists in the input PDF and it has to be related , the output file gets broken. otherwise, it gets OK, as a copy of the input file.

 

Thank You

Hi,

Can you please provide us with the input file as well so that we can more accurately determine the cause of the problem.

Thanks.

Hi,
Yes sure. I somehow missed to provide it.
Here it is.
Thank You

Hi,

I have been able to reproduce this error. I have logged this issue as PDFKITNET-3790 into our issue tracking system. Our developers will try their best to rectify this problem as soon as possible.

Thanks.

Hi,

you can go to the page (http://www.aspose.com/Community/Forums/thread/96008.aspx )

to download the new dll to test. this problem has been solved in the new fix version.

but until now, the function of replacing text is not perfect, for some special document, it may exist some problems. we will try best to improve this function.

Hello,

I am sorry to say but the replaceText method of this API is a complete failure. I wrote the same syntax as you in version 2.0 as well as 2.1 which is the latest release with all hot fixes. i.e.

 PdfContentEditor pdfContent = new PdfContentEditor();
        try{
            pdfContent.bindPdf("c:\\Curves.pdf");
            pdfContent.replaceText("curve", "ZZZZZZZZ");
            pdfContent.save("c:\\ReplacedCurves.pdf");
        }catch(Exception ex){
            ex.printStackTrace();
        }

But now i am getting the execption below :

java.lang.NullPointerException

at com.aspose.pdf.kit.f4.a(Unknown Source)

at com.aspose.pdf.kit.PdfContentEditor.replaceText(Unknown Source)

at Test.main(Test.java:56)

 

Thanks & Regards

Hello I  have attached x.pdf. please try to replace

Gramm-Leach-Bliley in this document with any word. Try to change Edward L. Stull with any other word. observe that it will not work. also see that the justification of the document gets distorted in the output pdf file.

 

Thanks & Regards

Anand

I did find with PDF files that wouldn't replace the text I could open it save it and then open it again at which point the replace function would work.   Not sure what pdfkit does when it writes out the file but it seems to like it when it reads it in again.

pdfContent.BindPdf("c:\\temp\\junk.pdf");

pdfContent.Save("c:\\temp\\junk2.pdf");

pdfContent.BindPdf("c:\\temp\\junk2.pdf");

pdfContent.ReplaceText("Sept", "Oct");

pdfContent.Save("c:\\temp\\Replaceddate.pdf");

Hope they find a solution to this.

 

Hello mark,

 

Thanks for considering Aspose.

 

Please share the Pdf file that you are using, so that we can test the issue at our end.

Hi Mark,

You are using a .NET edition of Aspose.Pdf.Kit, so the workaround may not work for Anand's project which uses a JAVA Kit. But your solution is very special and may be useful to us. Could you pease share the source Pdf file here to help us to resolve the issue?

Thank you,

I have a three for one special. The first file junk.pdf is the starting pdf.  Junk2 is the file after aspose saves it out and the third file  is after I have replaced some text in junk2.  I will say that it might have something to do with color in the pdf.  I will be getting my license soon so I will try it with the full version shortly.

 

Hi Anand,

The issue of PdfKitJava-6004 has resolved, and we also added a new method of PdfContentEditor.replaceText(String, int, String) for replacing words in one appointed page. Please download the attached Beta version(2.1.0.4) of aspose.pdf.kit.jar and try it.

Note that replacing words like Gramm and Edward with any words could be supported, but words such as "Gramm-Leach-Bliley" and "Edward L. Stull" may not be successfully replaced with other words by this Beta version. We will try to enhance the feature to support the latter form of words in our next version.

Thanks,
