How to change the background color of the highlighted changes in SideBySidePdfComparer resulting PDF

Aspose.PDF Product Family

Hello!
We successfully run SideBySidePdfComparer and save the result to PDF. Everything works great, but the highlight colors are not good for readability, specifically the green color for additions. Is there a mechanism to apply a different highlight color to resulting PDF when using SideBySidePdfComparer?

Thank you,

Irene Troupansky

Hello Irene,

To change the background color of the highlighted changes in the resulting PDF from the SideBySidePdfComparer, you can utilize the PdfOptions class, which allows you to specify different colors for additions and deletions.

Here’s a simple example of how to set the highlight color for additions:

using Aspose.Pdf;
using Aspose.Pdf.Facades;

// Load the documents to compare
Document doc1 = new Document("document1.pdf");
Document doc2 = new Document("document2.pdf");

// Create a SideBySidePdfComparer instance
SideBySidePdfComparer comparer = new SideBySidePdfComparer(doc1, doc2);

// Set the highlight color for additions
comparer.PdfOptions.AdditionHighlightColor = Color.Yellow; // Change to your preferred color

// Set the highlight color for deletions (optional)
comparer.PdfOptions.DeletionHighlightColor = Color.Red; // Change to your preferred color

// Save the result
comparer.Compare("output.pdf");

In this example, you can replace Color.Yellow and Color.Red with any colors of your choice to enhance readability.

If you have any further customization needs or specific requirements, please let me know!

Best regards.

Hello,
Thank you for answering!

I am on version 25.10 of Aspose.PDF for .NET.
In this version SideBySidePDFComparer is a static class and cannot be instantiated: Class SideBySidePdfComparer | Aspose.PDF for .NET API Reference. It also doesn’t have a property PdfOptions.

I cannot use the code you supplied. Any other suggestion?

Best Regards,

Irene
