Could you please guide us on we can achieve below –
Our customers upload PDF documents on our portal. We need to convert them to PDF/A, while doing so, we need to embed the fonts and replace any missing fonts with some default font .
When we are using document.validate() method (https://docs.aspose.com/pdf/net/convert-pdf-file-to-other-formats/#convert-pdf-file-to-pdf-a) it logs some font related error in xml but found the fonts are embedded.
We are using Aspose.PDF version 17.3
- How we will come to know which fonts are not embedded and we need to replace them.
- How to replace all missing fonts with default font without modifying the formatting of the text (color, bold, italics etc.).
- Should not impact any images in the document.
