Each layer may be - * retrieved as a full frame BufferedImage, or as a smaller image with an - * offset if the layer does not occupy the full frame size. Transparency - * in the original psd file is preserved in the returned BufferedImage's. - * Does not support additional features in PS versions higher than 3.0. - * Example: - * 
- *    PSDReader r = new PSDReader();
- *    r.readData("sample.psd");
- *    int n = r.getFrameCount();
- *    for (int i = 0; i < n; i++) {
