(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.");
});
Members

(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;
(readonly) errorCode :number
Gets the errorCode if there is a failure during conversion process.

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.
Returns:
The cancelled request.
Example
var conversionRequest = viewerControl.requestDocumentConversion();
conversionRequest.cancel();
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.
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
Example
var conversionRequest = viewerControl.requestDocumentConversion();
var convertedUrls = conversionRequest.getConvertedDocumentDownloadURLs();
getErrorCode() → {string}
Gets the error code for the conversion request, in cases where the request has failed.
Returns:
A value for programmatic identification of an error condition, or null if an error has not occurred.
- Type
- string
Example
var conversionRequest = viewerControl.requestDocumentConversion();
var errorCode = conversionRequest.getErrorCode();
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.
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
Example
var conversionRequest = viewerControl.requestDocumentConversion();
var options = conversionRequest.getOptions();
getProgress() → {number}
Gets the currently known conversion progress value.
Returns:
A number between 0 and 100 (inclusive). A value of 100 means the conversion process completed.
- Type
- number
Example
var conversionRequest = viewerControl.requestDocumentConversion();
var percent = conversionRequest.getProgress();
getWorkerID() → {string|null}
Gets the ID of the PCCIS ContentConverter performing conversion.
Returns:
The ID of the PCCIS ContentConverter performing conversion. Returns null before the worker is created.
- Type
- string | null
Example
var conversionRequest = viewerControl.requestDocumentConversion();
var workerId = conversionRequest.getWorkerID();
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.
Parameters:
| Name | Type | Description |
|---|---|---|
eventType |
string |
A string specifying the event type. See PCCViewer.ConversionRequest.EventType for a list and description of all supported events. |
handler |
PCCViewer.Event~eventHandler |
A function that was attached previously to the Note: This must be the same function object previously passed to PCCViewer.ConversionRequest#on. It cannot be a different object that is functionally equivalent. |
- See:
-
- PCCViewer.ConversionRequest#on
- PCCViewer.ViewerControl#off for more details on unsubscribing event handlers.
Returns:
The ConversionRequest object on which this method was called.
on(eventType, handler) → {PCCViewer.ConversionRequest}
Subscribe an event handler to an event of a specified type.
Parameters:

then(onFulfilledopt, onRejectedopt) → {PCCViewer.Promise}
Register callbacks to access the current or eventual result of the ConversionRequest.
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.
Parameters:

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