Class: ConversionRequest

(protected) new ConversionRequest()

The ConversionRequest object is created when converting a document using PCCViewer.ViewerControl#requestDocumentConversion.

The ConversionRequest is a thenable object, which allows Promise-like interactions. Calling the PCCViewer.ConversionRequest#then method will return a PCCViewer.Promise object. On successful conversion, the Promise success method, if added, is called with an array of the urls to download the converted documents. Note that it currently only supports converting to a single PDF file, so the output array will only contain a single URL. On a conversion failure, the Promise is rejected.

Note that if you create a ConversionRequest object using the PCCViewer.ViewerControl#convertDocument method, which has been marked as deprecated, the Promise success method is called with a single URL string (not an array of URL strings).

The ConversionRequest object also provides an event subscription method, to get notified of other types of information. See PCCViewer.ConversionRequest.EventType.

Note: This constructor should not be used directly. Instead, a ConversionRequest is created by a call to PCCViewer.ViewerControl#requestDocumentConversion.

Example

function onSuccessfulConvert(convertedDocumentUrls) {
   alert("The first converted document url: " + convertedDocumentUrls[0]);
}

function onFailedConvert(error) {
  alert("conversion process failed, reason: " + (error.message ? error.message : error));
}

// A ConversionRequest object is created by and returned from the call to the ViewerControl#requestDocumentConversion method
var conversionRequest = viewerControl.requestDocumentConversion();
conversionRequest.then(onSuccessfulConvert, onFailedConvert);

//register some events
conversionRequest
  .on(PCCViewer.ConversionRequest.EventType.ConversionCompleted,
      function(ev) {
          alert("Document conversion completed.");
      })
  .on(PCCViewer.ConversionRequest.EventType.ConversionProgress,
      function(event) {
          alert("Conversion progress: " + event.percent + "%");
      })
  .on(PCCViewer.ConversionRequest.EventType.ConversionFailed,
      function(event) {
          alert("Document conversion failed.");
      });

See:

(readonly) convertedDocumentDownloadURLs :string|null

Gets the URLs for downloading each converted document after successful conversion.

This property is defined on all ConversionRequest objects.

This is an ECMA 5 accessor property that is defined only in browsers supporting ECMA 5. This property is not available in the older browsers like IE8. For the greatest browser compatibility, use the corresponding getter and setter methods.

Example

var downloadUrls = conversionRequest.convertedDocumentDownloadURLs;

Type:

string | null

See:

PCCViewer.ConversionRequest#getConvertedDocumentDownloadURLs

(readonly) errorCode :number

Gets the errorCode if there is a failure during conversion process.

This property is defined on all ConversionRequest objects.

Example

var errorCode = conversionRequest.errorCode;

Type:

number

See:

PCCViewer.ConversionRequest#getErrorCode

(readonly) options :Object

Gets the options that were provided/used to convert the document.

This property is defined on all ConversionRequest objects.

Example

var options = conversionRequest.options;

Type:

Object

See:

PCCViewer.ConversionRequest#getOptions

(readonly) progress :number

Gets the current estimate of the conversion process progress.

This property is defined on all ConversionRequest objects.

Example

var percentProgress = conversionRequest.progress;

Type:

number

See:

PCCViewer.ConversionRequest#getProgress

(readonly) workerID :number

Gets the worker ID.

This property is defined on all ConversionRequest objects.

Example

var percentProgress = conversionRequest.workerID;

Type:

number

See:

PCCViewer.ConversionRequest#getWorkerID

Methods

cancel() → {PCCViewer.ConversionRequest}

Cancels the conversion request. The PCCViewer.Promise object that is returned will be rejected. If the user cancels the operation, then a PCCViewer.Error object will be returned as the rejection reason and its code property will be set to UserCancelled.

Example

var conversionRequest = viewerControl.requestDocumentConversion();
conversionRequest.cancel();

Returns:

The cancelled request.

Type: PCCViewer.ConversionRequest

getConvertedDocumentDownloadURL()

Deprecated since v11.0 (use the PCCViewer.ConversionRequest#getConvertedDocumentDownloadURLs method instead).

getConvertedDocumentDownloadURLs() → {string|null}

Gets the URLs for a web tier service to download each converted document.

Example

var conversionRequest = viewerControl.requestDocumentConversion();
var convertedUrls = conversionRequest.getConvertedDocumentDownloadURLs();

Returns:

Returns an array of URLs to download the converted documents. If called before the process completes, or after the process fails, it will return null.

Type: string | null

getErrorCode() → {string}

Gets the error code for the conversion request, in cases where the request has failed.

Example

var conversionRequest = viewerControl.requestDocumentConversion();
var errorCode = conversionRequest.getErrorCode();

Returns:

A value for programmatic identification of an error condition, or null if an error has not occurred.

Type: string

getOptions() → {Object}

Gets a copy of the options object used by the conversion request.

The original options object has been provided to the method PCCViewer.ViewerControl#requestDocumentConversion. If no options object was provided to requestDocumentConversion, or the options object did not define all properties, then the returned object will represent the actual options used.

Example

var conversionRequest = viewerControl.requestDocumentConversion();
var options = conversionRequest.getOptions();

Returns:

A copy of the conversion options object which is used by this conversion request.

targetExtension {string} - (optional) Whether to convert the signatures.
filename {string} - (optional) The format to which the document will be converted.

Type: Object

getProgress() → {number}

Gets the currently known conversion progress value.

Example

var conversionRequest = viewerControl.requestDocumentConversion();
var percent = conversionRequest.getProgress();

Returns:

A number between 0 and 100 (inclusive). A value of 100 means the conversion process completed.

Type: number

getWorkerID() → {string|null}

Gets the ID of the PCCIS ContentConverter performing conversion.

Example

var conversionRequest = viewerControl.requestDocumentConversion();
var workerId = conversionRequest.getWorkerID();

Returns:

The ID of the PCCIS ContentConverter performing conversion. Returns null before the worker is created.

Type: string | null

off(eventType, handler) → {PCCViewer.ConversionRequest}

Unsubscribe an event handler from a specified event type.

Typically, an event is unsubscribed when you no longer want further notification of the event.

then(onFulfilledopt, onRejectedopt) → {PCCViewer.Promise}

On successful conversion, the onFulfilled callback(s) are called with the URL to download the converted document.

On a conversion failure, the onRejected callback(s) are called with a PCCViewer.Error.

Multiple onFulfilled or onRejected callbacks can be registered for the same ConversionRequest by calling this method multiple times.

Example

var viewerControl = $("#myElement").pccViewer(...).viewerControl;

// a basic example
viewerControl.requestDocumentConversion().then(
    function onFulfilled(url) {
       // download document using `url`
    },
    function onRejected(error) {
        // Handle failure
    }
);

Parameters:

Name	Type	Attributes	Description
`onFulfilled`	PCCViewer.Promise~onFulfilled	<optional>	Called if or when the promise is resolved. Optionally pass a value of `null` or `undefined` if you do not use this callback, but you want to provide an onRejected callback.
`onRejected`	PCCViewer.Promise~onRejected	<optional>	Called if or when the promise is rejected.

Returns:

A promise object that is resolved according to the Promises/A+ standard.

Type: PCCViewer.Promise
