Clarification on Changing Redline Identifier in Aspose Library

Aspose.Words Product Family

Hi Team,

I am comparing two PDF files using the Aspose Library. The response generates a third document with redlining.

Can we modify the identifier to highlight where changes have occurred? Currently, a red line appears on the left in the attached PDF. Is it possible to adjust its thickness?

I am using the following code to change the color of the revision marks in the output document:
Code:

original.compare(revised, "AuthorName", new java.util.Date(), options);
RevisionOptions revisionOptions = original.getLayoutOptions().getRevisionOptions();
revisionOptions.setInsertedTextColor(RevisionColor.DARK_YELLOW); // Color for insertions
revisionOptions.setDeletedTextColor(RevisionColor.RED);          // Color for deletions
revisionOptions.setRevisedPropertiesColor(RevisionColor.DARK_YELLOW);

Is this the correct approach, or are there alternative methods we should consider? Will this configuration work for Word files as well? This is important as we plan to convert Word files to PDF later using the GroupDocs library.

Looking forward to your insights. Attaching a pdf for your reference.

Can you please specify what you mean by ‘changing the redline identifier’? Are you referring to the identifier for the revision marks or something else? Additionally, could you clarify what you mean by adjusting the thickness of the red line?

@munish.singla Using RevisionOptions you can configure revision appearance when document is rendered, i.e. saved to fixed page formats, like PDF, Image, XPS etc. These setting do not affect the document appearance in MS Word, when the document is saved as DOCX, because these setting are not stored in the document. They are set in MS Word application:

So, if you change RevisionOptions, save document as DOCX and then convert DOCX document to PDF using some other tool, the changes made in RevisionOptions will not have any effect.

Hi @alexey.noskov

When saving a file in .pdf format using the code below, the color coding works fine. However, for the .docx file, the same color coding is not applied correctly.
OutputAspose.docx (110.4 KB)

OutputAspose.pdf (194.4 KB)

I also have a question regarding the identifier visible in the .pdf file. Is it possible to change its color and thickness? You can see the issue in the screenshot:

Code:

original.compare(revised, "AuthorName", new java.util.Date(), options);
		
RevisionOptions revisionOptions = original.getLayoutOptions().getRevisionOptions();
revisionOptions.setInsertedTextColor(RevisionColor.DARK_YELLOW); // Color for insertions
revisionOptions.setDeletedTextColor(RevisionColor.BLUE);          // Color for deletions
       
original.save("OutputAspose.pdf");
original.save("OutputAspose.docx");

Can you please provide insights into why the color coding differs between .pdf and .docx and how to fix it? Additionally, any guidance on modifying the identifier’s color and thickness would be appreciated.

@munish.singla As I have mentioned revision options are not stored in DOCX documents. They are set on application level in MS Word. So there is no way to control revision appearance in MS Word using Aspose.Words.
