Wrong output when diving word document into single page documents

Hi,

I am trying to divide a document into single page documents. I have used document splitter. But it is giving me incorrect output. I am attaching my main document (Main.docx) and the output (which is 5 pages but it should be 4 , 3.docx is incorrect).

Also attaching my code files –

Please help. We are struck at this.

@saurabh.arora,

Thanks for your inquiry. Please try following code example. Hope this helps you.

Document doc = new Document(MyDir + "Main.docx");
int pagecount = doc.getPageCount();

NodeCollection paragraphs = doc.getChildNodes(NodeType.PARAGRAPH, true);
LayoutCollector collector = new LayoutCollector(doc);

for (Paragraph paragraph : (Iterable<Paragraph>) paragraphs) {
    for (Run run : paragraph.getRuns())
    {
        if(collector.getStartPageIndex(run) != collector.getEndPageIndex(run))
        {
            doc.getRange().replace(" ", " ", new FindReplaceOptions());
        }
    }
}

doc.updatePageLayout();
collector = new LayoutCollector(doc);
DocumentPageSplitter splitter = new DocumentPageSplitter(collector);
for (int page = 1; page <= pagecount; page++) {
    Document newDoc = splitter.GetDocumentOfPage(page);
    newDoc.save(MyDir + "output" + page + ".docx");
}

Hi Tahir,

Thanks for the reply . I tried the code but the problem still persists. Please see 3.docx (splitted into 2 pages). Attaching the code and the document folder.

Please suggest.

Hi @tahir.manzoor ,

Any update. We are really struck on this.

#12

@saurabh.arora,

Thanks for your inquiry. In your case, we suggest you please use Aspose.Words to convert each page of Word document into PDF and then use Aspose.Pdf to convert PDF document to DOC file format. Please check the following code examples. Hope this helps you.

 Document doc = new Document(MyDir + "Main.doc");
    using (Stream stream = File.Create(MyDir + "main_page3.pdf"))
    {
        PdfSaveOptions options = new PdfSaveOptions();
        options.PageIndex = 2;
        options.PageCount = 1;
        doc.Save(stream, options);
    }

var pdfDoc = new Document(dataDir + "main_page3.pdf");
var saveOptionsX = new Aspose.Pdf.DocSaveOptions
{
  Mode = DocSaveOptions.RecognitionMode.Flow,
  Format = DocSaveOptions.DocFormat.DocX,
};
pdfDoc.Save(dataDir + "main_page3.docx", saveOptionsX);

Hi Tahir,

Thanks for the reply. This is a sort of hack which will result in performance issues. Are we looking to solve our Page Splitting utility.

#14

@saurabh.arora,

Thanks for your inquiry. Please note that MS Word document is flow document and does not contain any information about its layout into lines and pages. Therefore, technically there is no “Page”, “Line” concept in Word document. Pages and lines are created by Microsoft Word on the fly so sometimes it’s hard to achieve 100% exact page layout.

If you do not want to use the suggested solution in my previous post, you can workaround this issue by using following code.

Document doc = new Document(MyDir + "Main.docx");

NodeCollection paragraphs = doc.getChildNodes(NodeType.PARAGRAPH, true);
LayoutCollector collector = new LayoutCollector(doc);

for (Paragraph paragraph : (Iterable<Paragraph>) paragraphs) {
    for (Run run : paragraph.getRuns())
    {
        if(collector.getStartPageIndex(run) != collector.getEndPageIndex(run))
        {
            doc.getRange().replace(ControlChar.NON_BREAKING_SPACE, " ", new FindReplaceOptions());
            doc.getRange().replace(" ", " ", new FindReplaceOptions());
        }
    }
}

doc.updatePageLayout();
int pagecount = doc.getPageCount();

collector = new LayoutCollector(doc);
DocumentPageSplitter splitter = new DocumentPageSplitter(collector);

for (int page = 1; page <= pagecount; page++) {
    Document newDoc = splitter.GetDocumentOfPage(page);
    if(newDoc.getFirstSection().getBody().getFirstParagraph().toString(SaveFormat.TEXT).trim().length() == 0)
    {
        newDoc.getFirstSection().getBody().getFirstParagraph().remove();
    }
    newDoc.save(MyDir + "output" + page + ".docx");
}

Hi Tahir,

I tried splitting the word document via pdf route. But it is giving me exception for large documents. Please find my code :

public class WordSplitViaPdf {

public static void main(String... args) throws Exception {

    com.aspose.pdf.License license = new com.aspose.pdf.License();
    com.aspose.words.License wordLicense = new  com.aspose.words.License();
    license.setLicense(new java.io.FileInputStream("/home/sauravarora/Desktop/aspose-licence"));
    wordLicense.setLicense("/home/sauravarora/Desktop/aspose-licence");

    PdfSaveOptions options = new PdfSaveOptions();
    com.aspose.pdf.DocSaveOptions docSaveOptions = new com.aspose.pdf.DocSaveOptions();
    docSaveOptions.setMode(com.aspose.pdf.DocSaveOptions.RecognitionMode.Flow);
    docSaveOptions.setFormat(com.aspose.pdf.DocSaveOptions.DocFormat.DocX);

    Document document = new Document("/home/sauravarora/data/1005/bulkupload/contracttemplate/1404/1523299617685/docWithoutContent.docx");
    String folder = "/home/sauravarora/data/1005/bulkupload/contracttemplate/1404/1523299617685";

    for (int page = 1; page <= document.getPageCount(); page++) {
        options.setPageIndex(page - 1);
        options.setPageCount(1);
        FileOutputStream fileOutputStreamForPdf = new FileOutputStream(folder + "/" + page + ".pdf");
        document.save(fileOutputStreamForPdf, options);
        FileOutputStream fileOutputStreamForWord = new FileOutputStream(folder + "/" + page + ".docx");
        FileInputStream fileInputStreamForPdf = new FileInputStream(folder + "/" + page + ".pdf");
        com.aspose.pdf.Document pdfDocument = new com.aspose.pdf.Document(fileInputStreamForPdf);
        pdfDocument.save(fileOutputStreamForWord, docSaveOptions);
    }
}

}

Also the exception trace :

Hi Tahir,

Thanks for the reply. I was just curious weather the aspose team has resolved the problem with word spitting code. The pdf approach is not optimum and leads to performance issue. I would be glad if we could solve problem with the word spitting code.

Thanks,
Saurabh
