Crate hipdf 

hipdf

A high-level PDF manipulation library built on lopdf, focusing on ease of use and powerful abstractions for common PDF operations.

Features

• OCG (Optional Content Groups) Support: Easy creation and management of PDF layers
• Layer Management: High-level API for organizing content into toggleable layers
• Content Building: Fluent API for building layered PDF content
• Type Safety: Strongly typed interfaces with compile-time guarantees
• WASM Support: Automatic configuration for WebAssembly targets

Example

use hipdf::ocg::{OCGManager, Layer, LayerContentBuilder, LayerOperations as Ops};
use lopdf::{Document, Object};

// Create a new PDF with layers
let mut doc = Document::with_version("1.5");
let mut ocg_manager = OCGManager::with_config(Default::default());

// Add layers
ocg_manager.add_layer(Layer::new("Background", true));
ocg_manager.add_layer(Layer::new("Main Content", true));

// Initialize layers in document
ocg_manager.initialize(&mut doc);
