How to remove a specific PDF annotation or comment in Node.JS

Node.JS users rejoice! Your PDF annotation-related problems are about to become a distant memory.

Let’s install the client we are using first.

"dependencies": {
    "cloudmersive-convert-api-client": "^2.1.6"
  }

Next we are going to write up the code for calling editPdfRemoveAnnotationItem. If you look at the following example setup, you will see how we instantiate our API first using a key, then proceed to call the above function using that instance.

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.apiKeyPrefix = 'Token';
var apiInstance = new CloudmersiveConvertApiClient.EditPdfApi();
var inputFile = "/path/to/file"; // File | Input file to perform the operation on.
var annotationIndex = 56; // Number | The 0-based index of the annotation in the document
var callback = function(error, data, response) {
if (error) {
console.error(error);
} else {
console.log('API called successfully. Returned data: ' + data);
}
};
apiInstance.editPdfRemoveAnnotationItem(inputFile, annotationIndex, callback);

Boom! Already done! The rest of this library includes a great deal of other handy functions for working with PDFs (and other document formats), such as splitting pages, merging, and rasterization.
