pdf_oxide 0.3.33

//! High-level PDF API for simple document creation and manipulation.
//!
//! This module provides a unified, easy-to-use API for common PDF operations:
//! - Creating PDFs from Markdown, HTML, or plain text
//! - Opening and editing existing PDFs with DOM-like navigation
//! - Querying and modifying document content
//! - Converting between formats
//!
//! ## Quick Start - Creating PDFs
//!
//! ```ignore
//! use pdf_oxide::api::Pdf;
//!
//! // Create from Markdown
//! let mut pdf = Pdf::from_markdown("# Hello World\n\nThis is a PDF.")?;
//! pdf.save("output.pdf")?;
//!
//! // Create from HTML
//! let mut pdf = Pdf::from_html("<h1>Hello</h1><p>World</p>")?;
//! pdf.save("output.pdf")?;
//! ```
//!
//! ## Opening and Editing PDFs with DOM Access
//!
//! ```ignore
//! use pdf_oxide::api::Pdf;
//!
//! // Open existing PDF
//! let mut doc = Pdf::open("input.pdf")?;
//!
//! // Get a page for DOM-like navigation
//! let page = doc.page(0)?;
//!
//! // Query elements
//! for text in page.find_text_containing("Hello") {
//!     println!("Found: {} at {:?}", text.text(), text.bbox());
//! }
//!
//! // Modify content
//! let mut page = doc.page(0)?;
//! let texts = page.find_text_containing("old");
//! for t in &texts {
//!     page.set_text(t.id(), "new")?;
//! }
//! doc.save_page(page)?;
//!
//! // Navigate DOM tree
//! let page = doc.page(0)?;
//! for element in page.children() {
//!     match element {
//!         PdfElement::Text(t) => println!("Text: {}", t.text()),
//!         PdfElement::Image(i) => println!("Image: {}x{}", i.width(), i.height()),
//!         _ => {}
//!     }
//! }
//!
//! // Save modifications
//! doc.save("output.pdf")?;
//! ```
//!
//! ## Builder Pattern
//!
//! For more control over PDF creation:
//!
//! ```ignore
//! use pdf_oxide::api::PdfBuilder;
//! use pdf_oxide::writer::PageSize;
//!
//! let mut pdf = PdfBuilder::new()
//!     .title("My Document")
//!     .author("John Doe")
//!     .page_size(PageSize::A4)
//!     .margins(72.0, 72.0, 72.0, 72.0)
//!     .from_markdown("# Content")?;
//! pdf.save("output.pdf")?;
//! ```
