Split a Word file by pages and a redundant page comes out

Aspose.Words Product Family

Hi there

I am testing splitting Word files by pages with Aspose Word 17.2.0 and PageSplitter.
Here is the test code:

@Test
public void splitTest() throws Exception{
    String fileName = "MAYJIANG_HAWAY_Improvement 2011.03.01.doc";
    String wordPassword = "";
    byte[] wordContent = IOUtils.toByteArray(new FileInputStream("custom/input/docx/"+fileName));
    splitMethod(wordContent, wordPassword, fileName);
}

protected void splitMethod(byte[] wordContent, String wordPassword, String fileName) throws Exception {
    Document wordDoc = null;

    try {
        if (StringUtil.isNotEmpty(wordPassword)) {
            LoadOptions loadOps = new LoadOptions(wordPassword);
            wordDoc = new Document(new ByteArrayInputStream(wordContent), loadOps);
        } else {
            wordDoc = new Document(new ByteArrayInputStream(wordContent));
        }

        String ext = FilenameUtils.getExtension(fileName);

        LayoutCollector layoutCollector = new LayoutCollector(wordDoc);
        wordDoc.updatePageLayout();
        DocumentPageSplitter splitter = new DocumentPageSplitter(layoutCollector);

        int totalPage = wordDoc.getPageCount();
        System.out.println("totalPage:" + totalPage);
        int index = 0;
        while (index < totalPage) {
            Document pageDoc = null;
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            File outputSinglePageWordFile = new File(
                    "custom/input/docx/" + "split_" + fileName + "/" + (index + 1) + "." + ext);
            FileUtil.md(outputSinglePageWordFile.getParentFile());
            try {

                pageDoc = splitter.getDocumentOfPage((index + 1));
                pageDoc.save(stream, SaveFormat.fromName(ext.toUpperCase()));

            } finally {
                IOUtils.closeQuietly(stream);
            }
            IOUtils.write(stream.toByteArray(), new FileOutputStream(outputSinglePageWordFile));
            index++;
        }
    } finally {
    }
}

In the result #1, opened with MS Word, you can see there is one more redundant empty page.

I have uploaded the origin Word file and the result.
Please check the attachment, and help us solve this issue, thanks~

Hi Craig,

Thanks for your inquiry. Please note your source document has empty paragraphs those creating the extra page issue in document splitting. Please remove empty paragraphs from your document before splitting the word document. Kindly check following code snippet for the purpose, it will help you to resolve the issue.

Document doc = new Document("MAYJIANG_HAWAY_Improvement+2011.03.01.doc");
for (Paragraph paragraph : (Iterable)doc.getChildNodes(NodeType.PARAGRAPH, true))
{
    if (paragraph.toString(SaveFormat.TEXT).trim().equals(""))
    {
        paragraph.remove();
    }
}

Please feel free to contact us for any further assistance.

Best Regards,

Hi there

I add the code snippet like this:

if (StringUtil.isNotEmpty(wordPassword))
{
    LoadOptions loadOps = new LoadOptions(wordPassword);
    wordDoc = new Document(new ByteArrayInputStream(wordContent), loadOps);
}
else
{
    wordDoc = new Document(new ByteArrayInputStream(wordContent));
}

for (Paragraph paragraph : (Iterable)wordDoc.getChildNodes(NodeType.PARAGRAPH, true))
{
    if (paragraph.toString(SaveFormat.TEXT).trim().equals(""))
    {
        paragraph.remove();
    }
}

The redundant page in split page #1 is gone
But the page header disappear as well, it is not like the result we want.
Please check the result again in the attachment.

Hi Tilal.Ahmad

Thanks for your information.
This code snippet works fine with this sample file.

I would like to share another sample file.
The positions of image and text block seem a little lower in the result.
Further more in result page #2, they are covered by the other contents.

Please check the attachment, and thank you for the help
