Usage notes
- From PDF 1.4 onwards the Version entry in the Catalog overrides the version declared in the file header, so make sure the actual content is compatible with the declared version
- Downgrading the version number may cause higher-version-specific features (such as incremental updates, object streams, and cross-reference streams) to be unrecognised by older readers
- Changes will only be persistent after calling the save method
