Nikhil Khandelwal updated CB-9819:
----------------------------------
Issue Type: Improvement (was: Bug)
> navigator.camera.getPicture returns a base64 string, not a data url.
> --------------------------------------------------------------------
>
> Key: CB-9819
> URL: https://issues.apache.org/jira/browse/CB-9819
> Project: Apache Cordova
> Issue Type: Improvement
> Components: Plugin Camera
> Reporter: Remco Haszing
> Priority: Minor

> When calling {{navigator.camera.getPicture}} with {{destinationType}} set to {{Camera.DestinationType.DATA_URL}}, the success function is called with the base64 encoded data. [RFC2397|http://tools.ietf.org/html/rfc2397] specified the data url should have the following format:
> {code}data:[<mediatype>][;base64],<data>{code}
> I would expect the data to be passed in this format, when a {{DATA_URL}} format is requested.
> The example in the README handles this _"bug"_
> {code:javascript}
> navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
> destinationType: Camera.DestinationType.DATA_URL
> });
> function onSuccess(imageData) {
> var image = document.getElementById('myImage');
> image.src = "data:image/jpeg;base64," + imageData;
> }
> function onFail(message) {
> alert('Failed because: ' + message);
> }
> {code}
> Instead I suggest the following options:
> * base64 encoded:
> {code:javascript}
> navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
> destinationType: Camera.DestinationType.BASE64_ENCODED
> });
> function onSuccess(imageData) {
> var image = document.getElementById('myImage');
> image.src = "data:image/jpeg;base64," + imageData;
> }
> function onFail(message) {
> alert('Failed because: ' + message);
> }
> {code}
> * data url:
> {code:javascript}
> navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
> destinationType: Camera.DestinationType.DATA_URL
> });
> function onSuccess(imageData) {
> var image = document.getElementById('myImage');
> image.src = imageData;
> }
> function onFail(message) {
> alert('Failed because: ' + message);
> }
> {code}
