示例1: readFrom
import javax.imageio.IIOImage; //導入方法依賴的package包/類
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())) {
n = n.getNextSibling();
}
if (n == null) {
throw new RuntimeException("No iTXt node!");
}
ITXtTest t = ITXtTest.getFromNode((IIOMetadataNode)n);
return t;
} catch (Throwable e) {
throw new RuntimeException("Reading test failed.", e);
