tengo este codigo:

 public static String scaleImage(ImageElement imageElement, String mime_type) { Canvas canvasTmp = Canvas.createIfSupported(); Context2d context = canvasTmp.getContext2d(); canvasTmp.setCoordinateSpaceWidth(imageElement.getWidth()); canvasTmp.setCoordinateSpaceHeight(imageElement.getHeight()); context.drawImage(imageElement, 0, 0, imageElement.getWidth(), imageElement.getHeight()); // How to set quality? String tempStr = canvasTmp.toDataUrl(mime_type); return tempStr; }

El problema con este código es que la String de salida tempStr es solo data:,
