Struct OcgVisibility 

pub struct OcgVisibility {
    pub on: HashSet<(u32, u16)>,
    pub off: HashSet<(u32, u16)>,
    pub default_on: bool,
}

Default OCG visibility derived from /Catalog → /OCProperties → /D.

Fields

on: HashSet<(u32, u16)>

Object IDs of OCGs that are ON by default.

off: HashSet<(u32, u16)>

Object IDs of OCGs that are OFF by default.

default_on: bool

When true, any OCG not listed in on/off is treated as visible (BaseState = ON, the PDF default).

Implementations

impl OcgVisibility

pub fn is_visible(&self, id: (u32, u16)) -> bool

Whether an OCG object id is visible under the catalog defaults.

pub fn is_empty(&self) -> bool

True when the document declares no OCG config (everything visible).
