How to Replace Text annotations in PDF documents using Cloud Java SDK

For replacing text annotations in PDF documents, we’ll use Aspose.PDF Cloud Java SDK This Cloud SDK allows you to easily build cloud-based PDF creator, editor & converter apps in Java language for various cloud platforms. Open Repository package manager, search for Aspose.PDF Cloud and install. You may also use the following command from the Package Manager Console for install it using Maven.

Add Aspose Cloud repository to your application pom.xml

Add Aspose Cloud repository


    <repositories>
        <repository>
            <id>aspose-cloud</id>
            <name>Aspose Cloud Repository</name>
            <url>https://releases.aspose.cloud/java/repo/</url>
        </repository>
    </repositories>

To install the API client library to your local Maven repository, simply execute:

Installation from Github


    mvn clean install

To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:

Deploy Maven repository


    mvn clean deploy

Steps to replace annotations using Java SDK

Aspose.PDF Cloud developers can easily load & replace annotations in PDF documents in just a few lines of code.

  1. Uploads the document to the cloud.
  2. Get Annotation using GetTextAnnotationAsync().
  3. Modify Annotation Contents and Icon.
  4. Save the Changes Back to the Cloud
  5. Downloads the updated document.
 

This sample code shows replacing Text Annotations in PDF document via Java

                // upload local PDF file to remote storage
                File file = new File(Path.of(LOCAL_FOLDER, PDF_DOCUMENT).toString());
                pdfApi.uploadFile(Path.of(REMOTE_FOLDER , PDF_DOCUMENT).toString(), file, null);
                System.out.println(String.format("File '%s' successfully uploaded!", Path.of(LOCAL_FOLDER, PDF_DOCUMENT).toString()));

                TextAnnotationResponse response = pdfApi.getTextAnnotation(PDF_DOCUMENT, ANNOTATION_ID, null, REMOTE_FOLDER);
                if (response.getCode() != 200)
                    System.err.println("Error: unexpected error when extracting annotation! '" + response.getStatus() + "'");
                else {
                    TextAnnotation result = response.getAnnotation();
                    result.setContents(REPLACED_CONTENT);
                    result.setIcon(TextIcon.STAR);

                    TextAnnotationResponse response2 = pdfApi.putTextAnnotation(PDF_DOCUMENT, ANNOTATION_ID, result, null, REMOTE_FOLDER);
                    if (response2.getCode() != 200)
                        System.err.println("Error: unexpected error when replacing annotation! '" + response.getStatus() + "'");
                    else{
                        // download changed PDF file from remote folder...
                        File f = pdfApi.downloadFile(Path.of(REMOTE_FOLDER , PDF_DOCUMENT).toString(), null, null);
                        java.nio.file.Files.copy(Path.of(f.getPath()), Path.of(LOCAL_FOLDER, PDF_OUTPUT), StandardCopyOption.REPLACE_EXISTING);
                        System.out.println(String.format("File '%s' successfully dowloaded!", Path.of(LOCAL_FOLDER, PDF_OUTPUT).toString()));                
                        System.out.println("Successfully added annotation in document ! '" + PDF_OUTPUT + "'");
                    }
                }
            }
            catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
 

Work with the annotations in PDF via Java SDK

Adding annotations to a PDF serves many important purposes across different use cases. One of the most common reasons is for review and feedback. Annotations let users highlight specific parts of a document, leave comments, ask questions, or suggest changes. This makes the review process more efficient and organized, especially when multiple collaborators are involved. Add the Annotations into PDF documents with Aspose.PDF Cloud Java SDK.

With our Java SDK you can

  • Add PDF document’s header & footer in text or image format.
  • Add tables & text or image stamps to PDF documents.
  • Append multiple PDF documents to an existing file.
  • Work with PDF attachments, annotations, & form fields.
  • Apply encryption or decryption to PDF documents & set a password.
  • Delete all stamps & tables from a page or entire PDF document.
  • Delete a specific stamp or table from the PDF document by its ID.
  • Replace single or multiple instances of text on a PDF page or from the entire document.
  • Extensive support for converting PDF documents to various other file formats.
  • Extract various elements of PDF files & make PDF documents optimized.
  • You can try out our free App to add the annotations into PDF files online and test the functionality.
