Aspose.PDF Product Family

Hi,

I have a pdf file which has some text like “HYPER_Google_1”(attached input.png file), I would like to replace this text with “Google”. However I dont want to display the anchor tag in the pdf file. My required output should be something like the attached output(expected_output file) pdf file.

Could you please help me with this requirement.

I tried with below sample code.

String key = “http://www.google.com/”;
key = “"”+key+“"”;
key = “Google”;
pdfContentEditor.replaceText(“HYPER_Google_1”, key);
//save output PDF
pdfContentEditor.save(“D:/Dharma/Aspose/word-hypderlink-issue/ReplaceTextOnAllPages.pdf”);
createHyperlink();
System.out.println(“Text replaced successfully!”);

Hi Dharmender,

Thanks for contacting support.

In order to accomplish your requirement, please try using the following code snippet. For your reference, I have also attached the resultant PDF generated over my end.

Java:

//open document
com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document("C:\\pdftest\\output.pdf");

//create TextAbsorber object to find
//all instances of the input search phrase
com.aspose.pdf.TextFragmentAbsorber
textFragmentAbsorber = new
com.aspose.pdf.TextFragmentAbsorber("<a href=\"http://www.google.com/\">Google</a>");
//accept the absorber for the first page of document
pdfDocument.getPages().accept(textFragmentAbsorber);

//get the extracted text fragments into collection
com.aspose.pdf.TextFragmentCollection
textFragmentCollection = textFragmentAbsorber.getTextFragments();

//get the first occurrence of text and replace
com.aspose.pdf.TextFragment textFragment =
textFragmentCollection.get_Item(1);

//update text and other properties
textFragment.setText("GOOGLE");
textFragment.getTextState().setFont(com.aspose.pdf.FontRepository.findFont("Verdana"));
textFragment.getTextState().setFontSize(12);

// save updated PDF file
pdfDocument.save("C:\\pdftest\\output_Text_Updated.pdf");

Hi Dharmender,

During my testing, I have used the latest release of Aspose.Pdf for Java 9.3.1 in Eclipse Juno application running over Windows 7 (x64) with JDK 1.7. Can you please share some details regarding your working environment i.e. API version, Operating System version, JDK version etc.

Now concerning to the requirement of adding hyperlinks in existing PDF file, the code snippet shared over following link can be used Add Hyperlink in PDF file. However I have observed that our API having some issues while adding hyperlink (the title and content of hyperlink are not visible in resultant file). For
the sake of correction, I have logged it in our issue tracking system as PDFNEWJAVA-34365. We will
investigate this issue in details and will keep you updated on the status of a
correction. We
apologize for your inconvenience.

Hi Dharmender,

I have further investigated the issue and have found that when replacing URL inside PDF, the hyperlink is also removed. However, in order to accomplish your requirement, you need to perform two steps. First, you need to replace the URL inside the PDF file and then add the hyperlink over the same location (where the replaced text is inserted). Please take a look at the following code snippet.

For your reference, I have also attached the output generated over my end.

[Java]

// Open document
com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document("C:\\pdftest\\output_pdf_from_word.pdf");

// Create TextAbsorber object to find all instances of the input search phrase
com.aspose.pdf.TextFragmentAbsorber textFragmentAbsorber = new com.aspose.pdf.TextFragmentAbsorber("<a href=\"http://www.google.com/\">Google</a>");

// Accept the absorber for the first page of the document
pdfDocument.getPages().accept(textFragmentAbsorber);

// Get the extracted text fragments into a collection
com.aspose.pdf.TextFragmentCollection textFragmentCollection = textFragmentAbsorber.getTextFragments();

// Get the first occurrence of text and replace
com.aspose.pdf.TextFragment textFragment = textFragmentCollection.get_Item(1);

// Update text and other properties
textFragment.setText("GOOGLE");
textFragment.getTextState().setFontSize(12);

// Create Link annotation object over the same position where the replaced text is inserted
com.aspose.pdf.LinkAnnotation link = new com.aspose.pdf.LinkAnnotation(pdfDocument.getPages().get_Item(1), new com.aspose.pdf.Rectangle(textFragment.getRectangle().getLLX(), textFragment.getRectangle().getLLY(), textFragment.getRectangle().getURX(), textFragment.getRectangle().getURY()));

// Create border object for LinkAnnotation
com.aspose.pdf.Border border = new com.aspose.pdf.Border(link);

// Set the border width value as 0
border.setWidth(0);

// Set the border for LinkAnnotation
link.setBorder(border);

// Specify the link type as a remote URI
link.setAction(new com.aspose.pdf.GoToURIAction("www.google.com"));

// Add link annotation to annotations collection of the first page of PDF file
pdfDocument.getPages().get_Item(1).getAnnotations().add(link);

// Save updated PDF file
pdfDocument.save("C:\\pdftest\\output_Updated.pdf");

Hi,

Thanx for your respone.

I have used the above code sample and tested on my standalone program it is working. But when i integrate the same code into application, it is giving Null pointer exception at pdfDoc.getPages().accept(textFragmentAbsorber);

Could you please help me in troubleshooting the issue.

Hi Dharmender,

During our testing with one of our sample PDF files, We did not notice any issue and it seems to be related to the source PDF file which you are using. Can you please share the resource file so that we can test the scenario at our end. We are sorry for this inconvenience.

Hi Dharmender,

In order to change the Font Size/Color of hyperlink, we in fact need to change the replaced text and as the hyperlink is placed over the same coordinates as the replaced text, so it will appear that hyperlink Size/Color is changed. Please try using the following code lines.

For your reference, I have also attached the resultant PDF file.

[Java]

//update text and other properties
textFragment.setText("GOOGLE");
textFragment.getTextState().setFontSize(22);
textFragment.getTextState().setForegroundColor(com.aspose.pdf.Color.getYellowGreen());

I am facing this issue on Unix machine but not facing this on windows machine.

i am using the latest aspose-pdf-9.3.1-jdk16 jar file for this.

Hi Dharmender,


As per my understanding, you are facing an issue while searching text inside PDF document because TextFragmentCollection being returned is 0 over Unix platform. I have logged this problem
as PDFNEWJAVA-34373 in our issue tracking system. We will further
investigate this problem and will keep you updated on the status
of correction. Please be patient and spare us little time. We are sorry for
this inconvenience.
