Struct Page 

pub struct Page {
    page_idx: usize,
    size: Size,
    layers: Layers,
}

A page of a PDF document.

This is a wrapper around a printpdf::PdfPageReference.

Fields

page_idx: usize

size: Size

layers: Layers

Implementations

impl Page

fn new(page_idx: usize, layer_id: LayerInternalId, size: Size) -> Page

pub fn add_layer(&mut self, name: impl Into<String>)

Adds a new layer with the given name to the page.

Examples

use genpdfi_extended::render::Renderer;
use genpdfi_extended::Size;

let mut r = Renderer::new(Size::new(210.0, 297.0), "ex").expect("renderer");
let page = r.get_page_mut(0).expect("page");
assert_eq!(page.layer_count(), 1);
page.add_layer("Extra");
assert!(page.layer_count() >= 2);

pub fn layer_count(&self) -> usize

Returns the number of layers present on the page.

Examples

use genpdfi_extended::render::Renderer;
use genpdfi_extended::Size;

let mut r = Renderer::new(Size::new(210.0, 297.0), "ex").expect("renderer");
let page = r.get_page_mut(0).expect("page");
assert_eq!(page.layer_count(), 1);
page.add_layer("L2");
assert!(page.layer_count() >= 2);

pub fn get_layer(&self, idx: usize) -> Option<Layer<'_>>

Returns the layer at the given index if it exists, otherwise None.

The returned value is a Layer wrapper that provides access to the layer’s drawing functionality.

Examples

use genpdfi_extended::render::Renderer;
use genpdfi_extended::Size;

let r = Renderer::new(Size::new(210.0, 297.0), "ex").expect("renderer");
let page = r.get_page(0).expect("page");
let layer = page.get_layer(0).expect("layer");
let _area = layer.area();

pub fn first_layer(&self) -> Layer<'_>

Returns the first layer of the page.

Examples

use genpdfi_extended::render::Renderer;
use genpdfi_extended::Size;

let r = Renderer::new(Size::new(210.0, 297.0), "ex").expect("renderer");
let page = r.get_page(0).expect("page");
let first = page.first_layer();
let last = page.last_layer();
// There is at least one layer and the areas are accessible
let _a = first.area();
let _b = last.area();

pub fn last_layer(&self) -> Layer<'_>

Returns the last layer of the page.

fn next_layer(&self, layer: &Rc<RefCell<LayerData>>) -> Layer<'_>
