示例1: readFrom
import javax.imageio.IIOImage; //导入方法依赖的package包/类
private static ITXtTest readFrom(File f) {
try {
ImageInputStream iis = ImageIO.createImageInputStream(f);
ImageReader r = ImageIO.getImageReaders(iis).next();
r.setInput(iis);
IIOImage dst = r.readAll(0, null);
// look for iTXt node
IIOMetadata m = dst.getMetadata();
Node root = m.getAsTree(m.getNativeMetadataFormatName());
Node n = root.getFirstChild();
while (n != null && !"iTXt".equals(n.getNodeName())) {
