Aspose.Words - save docx to HTML_FIXED - differences in line breaks

Aspose.Words Product Family

Hi,

We noticed differences in line breaks between the Word document and the result saved as HTML_FIXED.
Input file:
mini.docx (3.7 MB)

Code:

private void convertDocxToHtml(String docxPath, String htmlPath) throws Exception {
    Document doc = new Document(docxPath);
    doc.save(htmlPath, new HtmlFixedSaveOptions());
}

Document view:

845×257 5.69 KB

Html view:

858×237 6.44 KB

Unfortunately, such differences in appearance are not acceptable to us.

  1. What is the cause of such behavior?
  2. Is it possible to prepare the document in such a way that the line break does not change?

@mariusz.bajan The problem occurs because advanced typography features are used in your document. Advanced typography features are supported by Aspose.Words via Aspose.Words.Shaping.HarfBuzz package.

<dependency>
	<groupId>com.aspose</groupId>
	<artifactId>aspose-words</artifactId>
	<version>24.4</version>
	<classifier>shaping-harfbuzz-plugin</classifier>
</dependency>

You should install the above package and modify the code as shown below:

Document doc = new Document("C:\\Temp\\in.docx");
doc.getLayoutOptions().setTextShaperFactory(com.aspose.words.shaping.harfbuzz.HarfBuzzTextShaperFactory.getInstance());
doc.Save(@"C:\Temp\out.pdf");

This work properly for PDF, but is not yet supported for HmlFixed.

@mariusz.bajan You can use the following code as a workaround:

Document doc = new Document("C:\\Temp\\in.docx");
doc.getLayoutOptions().setTextShaperFactory(com.aspose.words.shaping.harfbuzz.HarfBuzzTextShaperFactory.getInstance());
// Update page layout.
doc.updatePageLayout();

HtmlFixedSaveOptions opt = new HtmlFixedSaveOptions();
opt.setPrettyFormat(true);
opt.setExportEmbeddedCss(true);
opt.setExportEmbeddedFonts(true);
opt.setExportEmbeddedImages(true);
opt.setExportEmbeddedSvg(true);

doc.save("C:\\Temp\\out_html_fixed.html", opt);
