- `UseAnnotFaces = 0x00000040`: Draw annotation appearances.
- `IsPrinting = 0x00000080`: The page is being printed.
- `DisplayOverPrintPreview = 0x00000100`: Display overprint preview.
- `UseTrapAnnots = 0x00002000`: Use trap network annotations.
- `DirectlyImposed = 0x00004000`: Directly imposed page.
- `IsPSPrinting = 0x00008000`: PostScript printing.
- `EmitPageGroup = 0x00010000`: Emit a page group.
- `UsePrinterMarkAnnots = 0x00020000`: Use printer's mark annotations.
