but JPEG encoder creates JPEG image, not PNG.

One thing i m confused about the swf is, i can handle jpeg image now, but what if the images are in png,gif,tiff or bmp format? hmm i think its done after i have written the image to disk, and then reading it back from the disk by BufferedInputStream, and finally writing to xml.

Why do you check the strings for equality, my purpose was to simply see the image on the mobile phone and I haven't really care what's going on under the hood more that I needed to, is the image data valid after the encoding/decoding?

Hi, i have problems about jpeg encoding/decoding.
i read jpeg data from xml tree by
str1 = imgEl.getChild(“jpegdata”).getText();
and then decode it by
imgBytes = Base64.decode(str1);
then i truncate the 4-byte jpeg header and build the bufferedimage by
imgData = truncateHeader(imgBytes);
ImageIO.read(new ByteArrayInputStream(imgData));
then i obey your suggestion about using jpegimageencoder
ByteArrayOutputStream baos = new ByteArrayOutputStream();
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(baos);
encoder.encode(image);
imgBytes2 = baos.toByteArray();
now; when i compare the first byte representation with the last one, i get no equalty and get different lengths.
boolean bool1 = imgBytes.toString().equals(imgBytes2.toString());
i was expecting to get equal byte arrays with this process..so what might be wrong here? any suggestions?
