Question

I am going to convert a Word Document (.docx) into images so I am using aspose.word.jar! The problem is that I am new to this work and using my code getting an error. My code part is:

public class NewClass {
   public static void main(String[] args){
       new NewClass().generateImages("D:\\Net Beans Work Space\\Text to Image\\Doc1.docx");
   }

   public void generateImages(final String sourcePath) {  
      try {  
           Document doc = new Document(sourcePath);  
           ImageSaveOptions options = new ImageSaveOptions(SaveFormat.JPEG);  
           options.setJpegQuality(100);  
           options.setResolution(100);  

           for (int i = 0; i < doc.getPageCount(); i++) {  
                String imageFilePath = sourcePath + "_output_" + i + ".jpeg";  
                options.setPageIndex(i);  
                doc.save(imageFilePath, options);  
           }  
      } catch (Exception e) {  
           e.printStackTrace();  
      }

You can look at apache POI ( http://poi.apache.org/ ) to convert docx to PDF. Then you can convert PDF to image with apache PDF box: http://pdfbox.apache.org/ — Athanor, Aug 14 '14 at 13:54
From PDF to image, you can use the ImageWriter: http://pdfbox.apache.org/docs/1.8.3/javadocs/org/apache/pdfbox/util/PDFImageWriter.html — Athanor, Aug 14 '14 at 19:55
Can you post your solution @user3411946 for future similar problems? — Athanor, Aug 18 '14 at 07:30

I have tested your code and it worked fine for me. Please make sure that you are using the latest version of Aspose.Words for Java.

If the issue persists, kindly share the word document that you are trying to convert. You can also upload your documents securely using our support forums.

Disclosure: I am a developer at Aspose.

Visit [Aspose.Words for Java](http://www.aspose.com/java/word-component.aspx) to download the latest version. Here is a direct link http://maven.aspose.com/repository/repo/com/aspose/aspose-words/14.7.0/aspose-words-14.7.0-jdk16.jar. – Saqib Aug 18 '14 at 08:33
saqib it says that evaluation purpose only what does it mean? – Java Nerd Aug 19 '14 at 07:41
If you don't apply a license, Aspose.Words for Java will run in evaluation mode. You can [buy](http://www.aspose.com/purchase/) or request a [free temporary license](http://www.aspose.com/corporate/purchase/temporary-license.aspx).

As docx is just a zip format you might use a Zip FileSystem to copy the image files to the outside.

    URI docxUri = file.toURI();
    docxUri = new URI("jar:" + docxUri.toString()); // "jar:file://..."

    final Path targetDirPath = Paths.get("C:/test");
    Files.createDirectories(targetDirPath);

    Map<String, String> zipProperties = new HashMap<>();
    zipProperties.put("encoding", "UTF-8");
    try (FileSystem zipFS = FileSystems.newFileSystem(docxUri,
            zipProperties)) {
        Path mediaPath = zipFS.getPath("/word/media");
        Files.walkFileTree(mediaPath, new SimpleFileVisitor<Path>() {

            @Override
            public FileVisitResult visitFile(Path path,
                    BasicFileAttributes attributes) throws IOException {
                String name = path.getFileName().toString();
                Path imgPath = Paths.get(targetDirPath.toString(), name);
                Files.copy(path, imgPath, StandardCopyOption.REPLACE_EXISTING);
                return super.visitFile(path, attributes);
            }
        });
    }

This copies all media files, found in zip folder /word/media.

Of course you have no metadata, no context to relate the image files. But it is a nice usage of Files.

i think the docx extension stands for MS Word 2007 so is this code for converting the MS Word Document to Images? — Java Nerd, Aug 18 '14 at 07:19
docx is an "open format" of MS Word. docx, xlsx are basically zip archives with XML for content and styles, and image files for images. If you rename the docx to .zip you'll see yourself. So I wanted to mention a solution with pure standard java. And the zip filesystem is wonderful too. _Nothing against Aspose._ — Joop Eggen, Aug 18 '14 at 07:28

the code is fine but how to take the .docx files an input from user.

the code itself has predefined path of the doc file which is about to be converted

what changes in the code should be done so that the application can take the document file from user and then generates its image

My Class:

import com.aspose.words.Document;
import com.aspose.words.ImageSaveOptions;
import com.aspose.words.SaveFormat;

/**
 * Created by white
 */
public class Program {

    public static void main(String args[]) throws Exception {


        new Program().generateImages("E:\\pro2\\Document.docx");

    }

    public void generateImages(final String sourcePath) {
        try {
            Document doc = new Document(sourcePath);
            ImageSaveOptions options = new ImageSaveOptions(SaveFormat.JPEG);
            options.setJpegQuality(100);
            options.setResolution(100);

            for (int i = 0; i < doc.getPageCount(); i++) {
                String imageFilePath = sourcePath + "_output_" + i + ".jpg";

                options.setPageIndex(i);

                doc.save(imageFilePath, options);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
