Class: ImageStamps

new ImageStamps(object)

The constructor for a ImageStamp Object. 'ImageStamp' object represents APIs for requesting the images and source from the server.

Parameters:

Name	Type	Description
`object`	object	with link to imageHandler URL.

Example

var options = { imageHandlerUrl: "../pcc.ashx" }
 var stamp = PCCViewer.ImageStamps(options);

Methods

getImageSourceURL(imageStampId)

Returns the image source URL for the imageStampId

Parameters:

Name	Type	Description
`imageStampId`	string

Example

var options = { imageHandlerUrl: "../pcc.ashx" }
 var stampApi = new PCCViewer.ImageStamps(options);

 var imageUrl = stampApi.getImageSourceURL(imageStampId);

reqestImageSourceBase64(imageStampId) → {PCCViewer.Promise}

Retrieves the dataUrl (base64 image source), and dataHash (unique id) from the server for the provided imagesStampId

If unable to retrieve image stamp data URL and dataHash from server, then the returned PCCViewer.Promise object is rejected with the reason set to a PCCViewer.Error object with its code property set to ImageStampDataFail.

If AJAX is not supported, then the returned PCCViewer.Promise object is rejected with the reason set to a PCCViewer.Error object with its code property set to AjaxUnsupported.

If a server error is encountered, then the returned PCCViewer.Promise object is rejected with the reason set to a PCCViewer.Error object with its code property set to Error.

Parameters:

Name	Type	Description
`imageStampId`	string

Returns:

a Promise object, on success returns a JSON object, on failure promise is rejected with reason. Returned JSON object will have dataUrl, and dataHash properties: dataUrl: base64 encoded image source dataHash: Encoded uique Id

Type: PCCViewer.Promise

Example

var options = { imageHandlerUrl: "../pcc.ashx" }
 var stampApi = new PCCViewer.ImageStamps(options);
 var imageStamps = {};
 var base64Source = null;

 var stampPromise = stampApi.requestImageStampList();

 stampPromise.then(
     function onSuccess(data) {
         imageStamps = data.imageStamps;
         var base64Promise = stampApi.reqestImageSourceBase64(imageStamps[0].id);

         base64Promise.then(
             function onSuccess(imageSource) {
                 base64Source = imageSource
                 var pageNumber = 1;
                 var rectangle = { x: 30, y: 30, width: 100, height: 100 };
                 var mark = viewer.viewerControl.addMark(pageNumber, "ImageStampAnnotation");
                 mark.setImage({ 
                     dataUrl: base64Source.dataUrl, id: base64Source.dataHash
                 });
                 mark.setRectangle(rectangle);
             }
         );

     },
     function onFailure(error) {
         alert(error.message ? error.message : error)
     }
 );

requestImageStampList(object) → {PCCViewer.Promise}

Retrieves the image stamp list from the server.

If a server error is encountered, then the returned PCCViewer.Promise object is rejected with the reason set to a PCCViewer.Error object with its code property set to Error.

If AJAX is not supported, then the returned PCCViewer.Promise object is rejected with the reason set to a PCCViewer.Error object with its code property set to AjaxUnsupported.

Parameters:

Name	Type	Description
`object`	object	with web handler link assigned to the `imageHandlerUrl` property.

Returns:

a Promise object.

Type: PCCViewer.Promise

Example

var options = { imageHandlerUrl: "../pcc.ashx" }
 var stampApi = new PCCViewer.ImageStamps(options);
 var imageStamps = {};
 var base64Source = null;

 var stampPromise = stampApi.requestImageStampList();

 stampPromise.then(
     function onSuccess(data) {
         imageStamps = data.imageStamps;
         var base64Promise = stampApi.reqestImageSourceBase64(imageStamps[0].id);

         base64Promise.then(
             function onSuccess(imageSource) {
                 base64Source = imageSource
                 var pageNumber = 1;
                 var rectangle = { x: 30, y: 30, width: 100, height: 100 };
                 var mark = viewer.viewerControl.addMark(pageNumber, "ImageStampAnnotation");
                 mark.setImage({ 
                     dataUrl: base64Source.dataUrl, id: base64Source.dataHash
                 });
                 mark.setRectangle(rectangle);
             }
