pdf2image

Provides functions for rendering a single page and one for rendering multiple pages

A simplified port of Python's pdf2image that wraps pdftoppm and pdftocairo (part of poppler) to convert PDFs to image::DynamicImages.

This library is a fork of https://github.com/styrowolf/pdf2image that replaces the usages of blocking multithreaded (rayon) with tokio async rendering. Which itself is a port of the python pdf2image library.

It wraps pdftoppm and pdftocairo (part of Poppler) under the hood, uses the "pdfinfo" from poppler to determine basic info about the pdf (number of pages and whether its encrypted)

This fork uses async rendering instead and allows the rendering of a single page or multiple pages with separate functions.

[!INFO] You must have poppler installed on your system in order to use this program it depends on the pdfinfo and

Installation

pdf2image requires poppler to be installed.

cargo add pdf2image_alt

Windows

Windows users will have to build or download poppler for Windows. Python's pdf2image maintainer recommends @oschwartz10612 version. You will then have to add the bin/ folder to PATH or use the environment variable PDF2IMAGE_POPPLER_PATH.

macOS

using homebrew:

brew install poppler

Linux

Most distros ship with pdftoppm and pdftocairo. If they are not installed, refer to your package manager to install poppler-utils

Platform-independent (Using `conda`)

Install poppler: conda install -c conda-forge poppler
Install pdf2image: pip install pdf2image

Quick Start

use pdf2image_alt::{render_pdf_multi_page, PDF2ImageError, PdfInfo, RenderOptionsBuilder};

#[tokio::main]
async fn main() -> Result<(), PDF2ImageError> {
    let data = std::fs::read("examples/pdfs/ropes.pdf").unwrap();
    let pdf_info = PdfInfo::read(data.as_slice()).await.unwrap();
    let options = RenderOptionsBuilder::default().pdftocairo(true).build()?;
    let pages = render_pdf_multi_page(
        &data,
        &pdf_info,
        pdf2image_alt::Pages::Range(1..=8),
        &options,
    )
    .await
    .unwrap();
    println!("{:?}", pages.len());

    Ok(())
}
