API

setParam

Define invocation parameters for ocrmypdf. See ocrmypdf --help for a list of available parameters.

Important

Parameters configured via setParam will override any other parameters or configurations set otherwise.

use mishagp\OCRmyPDF\OCRmyPDF;

//Passing a single parameter with a value
OCRmyPDF::make('document_zh-CN.pdf')
    ->setParam('-l', 'chi_sim')
    ->run();

//Passing a single parameter without a value
OCRmyPDF::make('document_withBackground.pdf')
    ->setParam('--remove-background')
    ->run();

//Passing multiple parameters
OCRmyPDF::make('document_withoutAttribution.pdf')
    ->setParam('--title', 'Lorem Ipsum')
    ->setParam('--keywords', 'Lorem,Ipsum,dolor,sit,amet')
    ->run();

setInputData

Pass image/PDF data loaded in memory into ocrmypdf directly via stdin.

use mishagp\OCRmyPDF\OCRmyPDF;

//Using Imagick
$data = $img->getImageBlob();
$size = $img->getImageLength();

//Using GD
ob_start();
imagepng($img, null, 0);
$size = ob_get_length();
$data = ob_get_clean();

OCRmyPDF::make()
    ->setInputData($data, $size)
    ->run();

setOutputPDFPath

Specify a writable path where ocrmypdf should generate output PDF.

use mishagp\OCRmyPDF\OCRmyPDF;
OCRmyPDF::make('document.pdf')
    ->setOutputPDFPath('/outputDir/ocr_document.pdf')
    ->run();

setExecutable

Define a custom location of the ocrmypdf executable, if by any reason it is not present in the $PATH.

use mishagp\OCRmyPDF\OCRmyPDF;
OCRmyPDF::make('document.pdf')
    ->setExecutable('/path/to/ocrmypdf')
    ->run();
