Word to PDF Converter online

Converting from Word to PDF format and vice versa is one of the most requested operations with office documents. Word document formats are great when you want to let other people make changes to the content. In contrast, the PDF format is an excellent choice when we need to protect the document from being modified. We need both of the unique features that Word and PDF formats provide. PDF and Word document formats complement each other in some cases and are therefore closely linked in today’s office work. Quite often we want to convert an editable Word document to an immutable PDF file. This may be a contract or some financial data that should not be modified.

What’s new in this release?

Earlier, Aspose.Words for .NET version 6.3 supported glossary documents while loading or saving Office Open XML only. But the newer version 6.4 enables exporting Word documents to PDF compliant to PDF/A-1b and Aspose.Words team is also committed to support PDF/A-1a in the next few months as well.

Example: How to export Word to PDF docs compliant to PDF/A-1b?

Document doc = new Document(@»C:TestRendering.doc»);
PdfOptions options = new PdfOptions();
options.Compliance = PdfCompliance.PdfA1b;
doc.SaveToPdf(0, doc.PageCount, @»C:TestRendering Out.pdf», options);

1. Добавьте зависимые библиотеки, необходимые для преобразования вложений на локальном компьютере.

Есть два способа добавить зависимости:

1) Настроить адрес удаленного склада aspose

Добавьте конфигурацию в файл settings.xml:

     <profile>

      <id>jdk-1.6</id>

      <activation>

        <jdk>1.6</jdk>

      </activation>

      <repositories>

        <repository>

        <id>AsposeJavaAPI</id>

        <name>Aspose Java API</name>

        <url>http://repository.aspose.com/repo/</url>

        </repository>

      </repositories>

</profile>

Затем проверьте зависимости, такие как aspose.email, aspose.words.aspose.excel, aspose.pdf с официального сайта, и добавьте их в файл pom. Такие как:

<dependency>

<groupId>com.aspose</groupId>

<artifactId>aspose-email</artifactId>

<version>20.3</version>

<classifier>jdk16</classifier>

</dependency>

2) Загрузите пакет jar в частную библиотеку, затем поместите загруженный пакет jar на локальный склад, а затем импортируйте его в проект локально по идее.

Адрес частной библиотеки:

https://repository.aspose.com/repo/com/aspose/

Импортировать шаги

File-> Project Structure ->Modules



2. Отладить функцию преобразования вложений, реализовать функцию преобразования изображений в PDF, преобразования слов в PDF и синтеза PDF в PDF.

Ниже показан эффект объединения двух изображений в PDF-файл, этапы реализации аналогичны, поэтому сначала посмотрите непосредственно на диаграмму эффекта:



Обратите внимание: при использовании почтальона для проверки слияния двух слов вам необходимо установить Content-Type = multipart / form-data в заголовках, в противном случае будет принято менее 2 файлов. Кроме того, в form-data вам необходимо установить ключ параметра для файла, чтобы выбрать файл для передачи в интерфейс в качестве параметра.



Изображение в функцию pdf:

1) Добавить зависимость:

 <dependency>
            <groupId>com.aspose</groupId>
            <artifactId>aspose-imaging</artifactId>
            <version>20.3</version>
            <classifier>jdk16</classifier>
</dependency>

Примечание. Репозиторий aspose необходимо указать в файле настроек.

Инструменты следующие:

package com.example.cn.service;

import com.aspose.imaging.Image;
import com.aspose.imaging.License;
import com.aspose.imaging.imageoptions.PdfOptions;

Объедините файлы pdf:

 public void mergePdfFiles(List<String> files, String newFile) throws IOException, DocumentException {
        PdfReader pdfReader = new PdfReader(files.get(0));
        Document document = new Document(pdfReader.getPageSize(1));
        pdfReader.close();
        PdfCopy copy = new PdfCopy(document, new FileOutputStream(newFile));
        document.open();
        for (int i = 0; i < files.size(); i++) {
            PdfReader reader = new PdfReader(files.get(i));
            int n = reader.getNumberOfPages();
            for (int j = 1; j <= n; j++) {
                document.newPage();
                PdfImportedPage page = copy.getImportedPage(reader, j);
                copy.addPage(page);
            }
            reader.close();
        }
        copy.close();
        document.close();
                 log.debug («Удаление одного файла»);
        files.forEach(e -> {
            File dateFile = new File(e);
            if (dateFile.exists()) {
                dateFile.delete();
            }
        });
    }

3. Реализуйте функцию локального преобразования электронных писем в PDF.

Идея реализации: сначала преобразовать тип электронной почты в html, затем в PDF, электронная почта -> html-> pdf

Чтобы передать параметры, content-Type = application / x-emf

Основной код выглядит следующим образом:



Преобразование электронной почты в HTML:

 public void emlToHtml(InputStream file, String path) {
        MailMessage messageEML = MailMessage.load(file);
        messageEML.save(path, SaveOptions.getDefaultHtml());
    }

Конвертировать html в pdf:

 public void emlToPdf(InputStream file,String path) throws Exception {

                 // ByteArrayInputStream преобразуется во входной поток
//        Presentation doc = new Presentation(file);
//        doc.save(path, SaveFormat.Pdf);
        emlToHtml(file,path);
                 // Конвертировать в PDF
        getLicense();
        Document doc = new Document(path);
        doc.save(path, SaveFormat.PDF);

//        getLicense();
//        Workbook workbook = new Workbook(file);
//        workbook.save(path, com.aspose.cells.SaveFormat.PDF);
    }

Перед конвертацией в pdf необходимо получить лицензию, то есть сертификат:

Проверьте, если лицензия не добавлена, между двумя PDF-файлами, синтезированными API, будет водяной знак aspose. следующим образом:

 

Появилась огромная яма! Проблема с водяными знаками очень велика, потому что она не решена, этот Peugeot слишком бросается в глаза, покупатель определенно будет недоволен, а затем попытается импортировать в соответствии с подсказкой.лицензия aspose.words, После перенаправления пакета водяной знак устранен!

  

Класс лицензии должен быть в пакете aspose.words:

Таким же образом: сначала получите лицензию, а затем конвертируйте eml в html файл в PDF.

Два письма без водяных знаков объединяются в один PDF-файл!
