Struct LinkObject

Source

pub struct LinkObject {
    pub rect: [f32; 4],
    pub quad_points: Option<Vec<f32>>,
    pub destination: Option<Destination>,
    pub action: Option<Action>,

Expand description

A typed view of a link annotation for introspection.

Wraps a reference to an Annotation of subtype Link and provides the upstream FPDFLink_* API surface: quad-point access, destination, and action retrieval.

Obtain via find_link_at_position or collect_links.

Fields§

§rect: [f32; 4]

Annotation rectangle [x1, y1, x2, y2].

§quad_points: Option<Vec<f32>>

QuadPoints (flat array of 8-float groups), if present.

§destination: Option<Destination>

The destination, if specified via /Dest.

§action: Option<Action>

The action, if specified via /A.

§annotation_index: usize

Index of this annotation in the page’s annotation list.

Implementations§

Source §

impl LinkObject

Source

pub fn quad_point_count(&self) -> usize

Returns the number of quad-point groups (quadrilaterals) on this link.

Each group is 8 floats [x1,y1, x2,y2, x3,y3, x4,y4].

Corresponds to FPDFLink_CountQuadPoints.

Source

pub fn link_count_quad_points(&self) -> usize

ADR-019 alias for quad_point_count().

Corresponds to FPDFLink_CountQuadPoints.

Source

pub fn count_quad_points(&self) -> usize

👎Deprecated since 0.1.0:

use link_count_quad_points() or quad_point_count() instead

Deprecated: use link_count_quad_points() or quad_point_count() instead.

Source

pub fn quad_points_at(&self, index: usize) -> Option<[f32; 8]>

Returns the index-th quad-point group as 8 floats, or None if the index is out of bounds.

Corresponds to FPDFLink_GetQuadPoints.

Source

pub fn link_get_quad_points(&self, index: usize) -> Option<[f32; 8]>

Upstream-aligned alias for quad_points_at().

Corresponds to FPDFLink_GetQuadPoints.

Source

pub fn get_quad_points(&self, index: usize) -> Option<[f32; 8]>

👎Deprecated since 0.1.0:

use link_get_quad_points() or quad_points_at() instead

Deprecated: use link_get_quad_points() or quad_points_at() instead.

Source

pub fn get_quad_points_at(&self, index: usize) -> Option<[f32; 8]>

👎Deprecated since 0.1.0:

use link_get_quad_points() or quad_points_at() instead

Deprecated: use link_get_quad_points() or quad_points_at() instead.

Source

pub fn dest(&self) -> Option<&Destination>

Returns the link’s destination, if any.

Corresponds to FPDFLink_GetDest.

Source

pub fn link_get_dest(&self) -> Option<&Destination>

ADR-019 alias for dest().

Corresponds to FPDFLink_GetDest.

Source

pub fn get_dest(&self) -> Option<&Destination>

👎Deprecated since 0.1.0:

use link_get_dest() or dest() instead

Deprecated: use link_get_dest() or dest() instead.

Source

pub fn action(&self) -> Option<&Action>

Returns the link’s action, if any.

Corresponds to FPDFLink_GetAction.

Source

pub fn link_get_action(&self) -> Option<&Action>

ADR-019 alias for action().

Corresponds to FPDFLink_GetAction.

Source

pub fn get_action(&self) -> Option<&Action>

👎Deprecated since 0.1.0:

use link_get_action() or action() instead

Deprecated: use link_get_action() or action() instead.

Source

pub fn rect(&self) -> [f32; 4]

Returns the link’s annotation rectangle.

Corresponds to FPDFLink_GetAnnotRect.

Source

pub fn link_get_annot_rect(&self) -> [f32; 4]

ADR-019 alias for rect().

Corresponds to FPDFLink_GetAnnotRect.

Source

pub fn get_annot_rect(&self) -> [f32; 4]

👎Deprecated since 0.1.0:

use link_get_annot_rect() or rect() instead

Deprecated: use link_get_annot_rect() or rect() instead.

Source

pub fn annotation_index(&self) -> usize

Returns the index of this link annotation in the page’s annotation list.

The caller can use this index to retrieve the full Annotation via page.annotations()[link.annotation_index()].

Corresponds to FPDFLink_GetAnnot — in PDFium this returns the annotation handle for a link; in rpdfium the equivalent is to look up the annotation by this index in the page’s annotation slice.
