I am using Java Aspose.PDF library (20.3) for converting the PDF to HTML. I found a case where the background in PDF is not appearing in HTML. Please see the attached image and input PDF with the resultant HTML. (The red background is not appearing in HTML.)
This is very critical to us as we use the converted HTML to show the preview of PDF to the user where he can make some corrections as well. Due to this issue, the user is not able to see the correct preview and not able to adjust the text properly.
