In Java, I can retrieve byte [] from Image with this code. However ImageIo class in codename1 does not support a write method.

    public byte[] getBytesFromImage(java.awt.Image image) {
        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        try {
            ImageIO.write((RenderedImage) image, "jpeg", stream);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return stream.toByteArray();
    }

Can you please advise an alternate codename1 method to convert a com.codename1.ui.Image in memory to a byte array?

What's RenderedImage? That's an AWT class.

Try:

ImageIO.save(img, outputStream, ImageIO.FORMAT_JPEG, 0.9f);

Please disregard the RenderedImage cast as this was copied from my Java Swing project

Getting "error: non-static method save(Image,OutputStream,String,float) cannot be referenced from a static context"

I have attached a basic class MyApplication to demonstrate the error.

Thanks in advance.

Sorry it should have been ImageIO.getInstance().save...
