## Description

Bitfield flags that control the display and behavior of annotations.

These flags are defined in the PDF specification (Table 165) and can be combined to control annotation visibility, printing, rotation, and interactivity.

## Values

- `Invisible = 0x01`: If there is no annotation handler, the annotation is invisible.
- `Hidden = 0x02`: The annotation is not visible and does not print.
- `Print = 0x04`: The annotation prints.
- `NoZoom = 0x08`: The annotation does not zoom with the view.
- `NoRotate = 0x10`: The annotation does not rotate with the page.
- `NoView = 0x20`: The annotation does not view but can print.
- `ReadOnly = 0x40`: The annotation does not interact with the user.
- `Lock = 0x80`: The annotation does not move or resize with the view. Only form fields respect this flag. If the annotation is locked, the user cannot delete, move or change its associated form field's properties.
- `ToggleNoView = 0x100`: A mouse-over or selection causes the noView bit to toggle.
- `LockContents = 0x200`: If the annotation is content-locked, the user can not change its content key.
