  size: 600               // output size in pixels
})

// by default the first page of the pdf will be converted
// to image
converter.convert("/path/to/pdf/sample.pdf")
  .then(resolve => {
    console.log("image converted successfully")
  })

// or you can also convert bulk
// in this example we will only convert pages 1 4 and 6

    console.log("image converted successfully")

// supplying -1 as second argument
converter.convertBulk("path/to/pdf/sample.pdf", -1)
  .then(resolve => {
    console.log("image converted successfully")
  })


// you can also directly convert pdf to base64 of an image
converter.convertToBase64("path/to/pdf/sample.pdf")
  .then(resolve => {
    if (resolve.base64) {
      // assuming you're using some ORM to save base64 to db
      db.model.table('users').update({id: "1", image: resolve.base64})
    }
  })
