ocrmypdf-rs

A Rust library that adds “layers” of text to images in PDFs, making scanned image PDFs searchable using ocrmypdf, which is a Python application and library.

Prerequisites

For everything to work correctly, you need to have it installed on your OS ocrmypdf.

Example

Debian or Ubuntu users can simply use the following:

sudo apt install ocrmypdf

For more information on how to install on different OS, see the installation documents.

Installation

Install ocrmypdf-rs with cargo;

[dependencies]
ocrmypdf-rs = "0.0.7"

Usage/Examples

Basic example ref.

use ocrmypdf_rs::{Ocr, OcrMyPdf};

fn main() {
    let mut ocr = OcrMyPdf::new(None, None, None);

    ocr.set_input_path("input.pdf".into())
        .set_output_path("output.pdf".into())
        .set_args(vec!["--force-ocr".into()])
        .execute();
}

new method

When instantiating the OcrMyPdf structure it is possible to pass the following parameters:

• args: Option<Vec<String>> see about arguments in documentation
• input_path: Option<String> input pdf path
• output_path: Option<String> output pdf path

[!TIP] 💡 If the input_path or output_path fields are provided, there is no need to provide them at runtime.

use ocrmypdf_rs::{Ocr, OcrMyPdf};

fn main() {
    let args: Vec<String> = vec!["-l por".into()];
    let input_path = "input.pdf";
    let output_path = "output.pdf";

    let mut ocr = OcrMyPdf::new(
        Some(args),
        Some(input_path.into()),
        Some(output_path.into()),
    );

    ocr.execute();
}

[!NOTE] The -l por args to work requires the additional selected language to be installed, see how install;
