Example 36 with IIOMetadata

use of javax.imageio.metadata.IIOMetadata in project jdk8u_jdk by JetBrains.

the class WBMPPluginTest method test.

public boolean test() throws IIOException, IOException {
    ir.reset();
    iw.reset();
    String[] suffixes = iw.getOriginatingProvider().getFileSuffixes();
    IIOMetadata md = iw.getDefaultImageMetadata(new ImageTypeSpecifier(img), param);
    IIOImage iio_img = new IIOImage(img, null, md);
    System.out.println("Image type " + img.getType());
    String fname = "test" + img.getType() + "." + suffixes[0];
    iw.setOutput(ImageIO.createImageOutputStream(new FileOutputStream(new File(fname))));
    System.out.print("write image ... ");
    iw.write(iio_img);
    System.out.println("OK");
    System.out.print("read image ... ");
    byte[] ba_image = baos.toByteArray();
    ByteArrayInputStream bais = new ByteArrayInputStream(ba_image);
    ir.setInput(ImageIO.createImageInputStream(new FileInputStream(new File(fname))));
    BufferedImage res = ir.read(0);
