Class Base64decoderStream

java.lang.Object

java.io.InputStream

totalcross.io.Base64decoderStream

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class Base64decoderStream
extends java.io.InputStream

Receive a stream of base64 encoded bytes and decode to the original.

Given a base 64 encoded image (img64), one may use:

 Image createImage(String img64) {
                ByteArrayStream bas = new ByteArrayStream(img64.getBytes()); // get a Stream to read the String
                InputStream stringInput = bas.asInputStream(); // use ByteArrayStream as a java.io.InputStream compliant object
    
                Base64decoderStream decoder = new Base64decoderStream(stringInput); // now we can read the original bytes
                Stream imgSource = Stream.asStream(decoder); // use Base64decoderStream as a totalcross.io.Stream compliant object
                return new Image(imgSource); // passing the stream directly to the image for the sake of memory
 }
