Note

Usage: Poppler

const { Poppler } = require('pdf-images');
const result = Poppler.convert('/pdf/path/sample_pdf.pdf', 'output/directory/path', 'outputName'); // you can also add a 4th arguement which can specify the output image extension like jpg or jpeg

• A successfull result will look something like:

{
  pdfPath: '/pdf/path/sample_pdf.pf',
  outputImagesDirectory: '/output/directory/outputName/',
  images: [
    '/output/directory/outputName/outputName-001.png',
    '/output/directory/outputName/outputName-002.png'
  ],
  success: true
}

• An error response will look something like:

{
  pdfPath: '/pdf/path/sample_pdf.pf',
  error: <Err object>
}

Usage: ImageMagick

Async api to convert

• By default images have png extension
• you can also add a string of the args that you want to run with the imagemagick shell command. checkout resultWithArgs

const { ImageMagick } = require('pdf-images');
const result = ImageMagick.convertAsync('/pdf/path/sample_pdf.pdf', 'output/directory/path', 'outputName');
const resultWithArgs = ImageMagick.convertAsync('/pdf/path/sample_pdf.pdf', 'output/directory/path', 'outputName', '-alpha background');
const resultWithDifferentExtension = ImageMagick.convertAsync(
  '/pdf/path/sample_pdf.pdf',
  'output/directory/path',
  'outputName',
  null,
  'jpeg',
);

• A successfull result will look something like:

{
  pdfPath: '/pdf/path/sample_pdf.pf',
  outputImagesDirectory: '/output/directory/outputName/',
  commandExecuted: 'convert -quiet -alpha background -density 200 -quality 100 /pdf/path/sample_pdf.pf /output/directory/outputName/outputName.jpeg',
  images: [
    '/output/directory/outputName/outputName-001.jpeg',
    '/output/directory/outputName/outputName-002.jpeg'
  ],
  success: true
}

const { ImageMagick } = require('pdf-images');
const result = ImageMagick.convert('/pdf/path/sample_pdf.pdf', 'output/directory/path', 'outputName'); // you can also add a 4th arguement which can specify the output image extension like jpg or jpeg

• A successfull result will look something like:

{
  pdfPath: '/pdf/path/sample_pdf.pf',
  outputImagesDirectory: '/output/directory/outputName/',
  images: [
    '/output/directory/outputName/outputName-001.png',
    '/output/directory/outputName/outputName-002.png'
  ],
  success: true
}

• An error response will look something like:

{
  pdfPath: '/pdf/path/sample_pdf.pf',
  error: <Err object>
}

• To set the density and quality of imagemagick use:

ImageMagick.setQuality(100);
ImageMagick.setDensity(200);

• Default ImageMagick quality is 100 and density is 200
