Saving BitmapData to the Camera Roll

danger

This functionality has been deprecated and will be removed in an upcoming release.

You should move to the CameraRollExtended extension for adding images to the Camera Roll.

Migration should be relatively straight forward, just replace the Image.service.saveToCameraRoll() with CameraRollExtended.service.addBitmapData().

Encoding bitmap data to a file can be a slow process when using AS3 operations. This extension provides functionality to use the native encoders to save BitmapData directly to the user's Camera Roll allowing them to have access to this image through their gallery application (Photos, Gallery, etc).

This operation is asynchronous. You will receive an event when the operation completes.

Authorisation

In order to save to the camera roll you should make sure that the user has granted your application permission to save to the camera roll. On Android this is a "dangerous" permission and requires runtime permission. On iOS it should always be granted.

Take a look at the Request Authorisation section for more information.

Example

This example uses an embedded image asset in the class SampleImage.

var image:Bitmap = new SampleImage() as Bitmap;
    
Image.service.addEventListener( ImageEvent.SAVE_TO_CAMERAROLL_COMPLETE, completeHandler );
Image.service.addEventListener( ImageEvent.SAVE_TO_CAMERAROLL_ERROR, errorHandler );
Image.service.saveToCameraRoll( image.bitmapData );

You will receive either an ImageEvent.SAVE_TO_CAMERAROLL_COMPLETE event or an ImageEvent.SAVE_TO_CAMERAROLL_ERROR event:

private function completeHandler( event:ImageEvent ):void
{
    trace( "saveToCameraRoll : complete" );
}

private function errorHandler( event:ImageEvent ):void
{
    trace( "saveToCameraRoll : error: "+event.error );
}
