This project is a Rust-based tool for cropping PDF documents based on the bounding box of the text content.

• Rust (https://www.rust-lang.org/tools/install)
• Cargo (comes with Rust)
• pdfium-render crate (https://crates.io/crates/pdfium-render)

To use the pdfium-render crate, you need to install the Pdfium library. Follow the instructions below based on your operating system:

1. Download the Pdfium library from the official repository:

   wget https://github.com/bblanchon/pdfium-binaries/releases/download/chromium%2F4706/pdfium-linux.tgz

2. Extract the downloaded file:

   tar -xzf pdfium-linux.tgz

3. Move the extracted files to a directory included in your library path, e.g., /usr/local/lib:

   sudo mv pdfium-linux/lib/* /usr/local/lib/

4. Update the library cache:

   sudo ldconfig

To build the project, run the following command in the project directory:

cargo build --release

This will create an optimized build of the project in the target/release directory.

To run the project, use the following command:

cargo run --release -- <input-pdf> <output-pdf>

Replace <input-pdf> with the path to the input PDF file and <output-pdf> with the path where you want to save the cropped PDF file.

cargo run --release -- input.pdf output.pdf

This command will crop the input.pdf file based on the bounding box of the text content and save the result to output.pdf.

To run the tests, use the following command:

cargo test

This will execute the tests defined in the project to ensure everything is working correctly.
