Hello team,
We are using the IWarningCallback interface to capture font warnings. This implementation works perfectly fine in Aspose version 20.12, but throws an error during document save in the latest version (26.9). …...SetFontsSources(updatedFontSources); var obj = new HandleDocumentWarnin();...; doc.WarningCallback = obj; worddoc1 = doc.Range.ToDocument();...
