Struct PdfDocumentModel 

pub struct PdfDocumentModel { /* private fields */ }

PDF 文档的引擎无关语义表示。

包含元数据与按页组织的语义内容块。

Implementations

impl PdfDocumentModel

pub const fn new(metadata: PdfMetadata, pages: Vec<PdfPageModel>) -> Self

创建文档模型。

pub const fn metadata(&self) -> &PdfMetadata

返回文档元数据。

pub fn pages(&self) -> &[PdfPageModel]

返回页面列表。

pub fn page_count(&self) -> usize

返回页面数量。

pub fn is_empty(&self) -> bool

判断文档是否不含页面。

pub fn iter(&self) -> impl Iterator<Item = &PdfPageModel>

返回页面迭代器。

pub fn total_blocks(&self) -> usize

返回所有页面中内容块的总数。

Examples

use easypdf_core::{PdfBlock, PdfDocumentModel, PdfPageModel, SourceLocation};
use easypdf_core::{PageIndex, PdfMetadata};

let loc = SourceLocation::new(PageIndex::new(0), 1.0);
let page = PdfPageModel::new(PageIndex::new(0))
    .with_block(PdfBlock::paragraph("A", loc))
    .with_block(PdfBlock::paragraph("B", loc));
let doc = PdfDocumentModel::new(PdfMetadata::default(), vec![page]);
assert_eq!(doc.total_blocks(), 2);

pub fn iter_all_blocks(&self) -> impl Iterator<Item = (usize, &PdfBlock)>

扁平遍历所有页面的内容块，附带一基页码。

返回迭代器产出 (page_number, &PdfBlock) 元组。

Examples

use easypdf_core::{PdfBlock, PdfDocumentModel, PdfPageModel, SourceLocation};
use easypdf_core::{PageIndex, PdfMetadata};

let loc = SourceLocation::new(PageIndex::new(0), 1.0);
let page = PdfPageModel::new(PageIndex::new(0))
    .with_block(PdfBlock::paragraph("Hello", loc));
let doc = PdfDocumentModel::new(PdfMetadata::default(), vec![page]);
let blocks: Vec<_> = doc.iter_all_blocks().collect();
assert_eq!(blocks.len(), 1);
assert_eq!(blocks[0].0, 1); // 1-based page number

pub fn block_count_by_type(&self) -> HashMap<PdfBlockType, usize>

统计每种 PdfBlockType 的出现次数。

Examples

use easypdf_core::{PdfBlock, PdfBlockType, PdfDocumentModel, PdfPageModel, SourceLocation};
use easypdf_core::{PageIndex, PdfMetadata};

let loc = SourceLocation::new(PageIndex::new(0), 1.0);
let page = PdfPageModel::new(PageIndex::new(0))
    .with_block(PdfBlock::heading(1, "Title", loc))
    .with_block(PdfBlock::paragraph("Body", loc));
let doc = PdfDocumentModel::new(PdfMetadata::default(), vec![page]);
let counts = doc.block_count_by_type();
assert_eq!(counts[&PdfBlockType::Heading], 1);
assert_eq!(counts[&PdfBlockType::Paragraph], 1);
