Steps to create a link via Java SDK

Aspose.PDF Cloud developers can easily load & create link in PDF in just a few lines of code.

  1. Initialize the Aspose PDF API
  2. Upload the PDF Document to Cloud Storage
  3. Reads a local link file and uploads it to the Aspose.PDF Cloud storage.
  4. Inserts the uploaded link into the uploaded PDF file at a specific location.
  5. Download the result if needed it
 

This sample code shows creating a link in PDF documents


    package com.aspose.asposecloudpdfusecases.links;

    import java.io.File;
    import java.nio.file.Path;
    import java.nio.file.StandardCopyOption;
    import com.aspose.asposecloudpdf.api.PdfApi;
    import com.aspose.asposecloudpdf.model.AsposeResponse;
    import com.aspose.asposecloudpdfusecases.AppHelper;

    public class linksAdd {
        public static void Append(){
            String LOCAL_FOLDER     = "C:\\Samples\\";
            String REMOTE_FOLDER    = "Your_Temp_Pdf_Cloud";
            String PDF_DOCUMENT     = "sample.pdf";
            String PDF_OUTPUT       = "output_sample_link_add.pdf";
            String link_FILE_NAME  = "sample.jpg";
            Integer PAGE_NUMBER     = 1;

            try{
                PdfApi pdfApi = new PdfApi(API_KEY, API_SECRET);

                // 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()));

                file = new File(Path.of(LOCAL_FOLDER, link_FILE_NAME).toString());
                pdfApi.uploadFile(Path.of(REMOTE_FOLDER, link_FILE_NAME).toString(), file, null);
                System.out.println(String.format("File '%s' successfully uploaded!", Path.of(LOCAL_FOLDER, link_FILE_NAME).toString())); 

                double llx = 10;
                double lly = 10;
                double urx = 100;

                AsposeResponse response = pdfApi.postInsertlink(PDF_DOCUMENT, PAGE_NUMBER, llx, lly, urx, ury, REMOTE_FOLDER + "/" + link_FILE_NAME, null, REMOTE_FOLDER, null);
                if (response.getCode() != 200)
                    System.err.println("Error: unexpected error when adding link to document! '" + 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 link to document ! '" + PDF_OUTPUT + "'");
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
