Example 41 with FinalInterval

use of net.imglib2.FinalInterval in project imagej-ops by imagej.

the class CopyRAITest method createData.

@Before
public void createData() {
    input = new ArrayImgFactory<UnsignedByteType>().create(new int[] { 120, 100 }, new UnsignedByteType());
    final Random r = new Random(System.currentTimeMillis());
    final Cursor<UnsignedByteType> inc = input.cursor();
    while (inc.hasNext()) {
        inc.next().setReal(r.nextDouble() * 255);
    }
    // create
    final long[] start = new long[] { 16, 16, 16 };
    final long[] end = new long[] { 47, 47, 47 };
    // create an input with a cube at the center
    input2 = ops.create().img(new FinalDimensions(size1), new UnsignedByteType());
    // create the same input but force it to be a planar image
    inputPlanar = ops.create().img(new FinalDimensions(size1), new UnsignedByteType(), new PlanarImgFactory<UnsignedByteType>());
    // get centered views
    view = Views.interval(input2, new FinalInterval(start, end));
    viewPlanar = Views.interval(inputPlanar, new FinalInterval(start, end));
    final Cursor<UnsignedByteType> cursor = view.cursor();
    final Cursor<UnsignedByteType> cursorPlanar = viewPlanar.cursor();
    // set every pixel in the view to 100
    while (cursor.hasNext()) {
        cursor.fwd();
        cursorPlanar.fwd();
        cursor.get().setReal(100.0);
