pdfcrop

A library and CLI tool for cropping PDF files with automatic bounding box detection.

This library provides functionality to:

• Detect bounding boxes of PDF content through content stream parsing
• Crop PDF pages with custom margins
• Support manual bounding box override
• Process PDFs page by page or in batch

Library Usage Example

use pdfcrop::{crop_pdf, CropOptions, BoundingBox, Margins};

let pdf_data = std::fs::read("input.pdf")?;

let options = CropOptions {
    margins: Margins::uniform(10.0),
    bbox_override: None,
    ..Default::default()
};

let cropped = crop_pdf(&pdf_data, options)?;
std::fs::write("output.pdf", cropped)?;
