Examples of javax.imageio.stream.FileImageInputStream

javax.imageio.stream.FileImageInputStream
An implementation of ImageInputStream that gets its input from a File or RandomAccessFile. The file contents are assumed to be stable during the lifetime of the object.

    public void load (InputStream is) throws IOException {
        this.image = ImageIO.read(is);
    }


    public void customLoad (RandomAccessFile raf) throws Exception {
    image = ImageIO.read(new FileImageInputStream(raf));
    }

        // must be .jpg or .jpeg. If extension not present, append
        // .jpg extension.
