Python OverlayPlugin Examples

Example #1

File: test_viewer.py Project: foogunlana/scikit-image

def test_viewer_with_overlay():
    img = data.coins()
    ov = OverlayPlugin(image_filter=sobel)
    viewer = ImageViewer(img)
    viewer += ov

    import tempfile
    _, filename = tempfile.mkstemp(suffix='.png')

    ov.color = 3
    assert_equal(ov.color, 'yellow')
    viewer.save_to_file(filename)
    ov.display_filtered_image(img)
    assert_equal(ov.overlay, img)
    ov.overlay = None
    assert_equal(ov.overlay, None)
    ov.overlay = img
    assert_equal(ov.overlay, img)
    assert_equal(ov.filtered_image, img)

Example #2

    ov = OverlayPlugin(image_filter=sobel)
    viewer = ImageViewer(img)
    viewer += ov

    import tempfile
    _, filename = tempfile.mkstemp(suffix='.png')

    ov.color = 3
    assert_equal(ov.color, 'yellow')
    viewer.save_to_file(filename)
    ov.display_filtered_image(img)
    assert_equal(ov.overlay, img)
    ov.overlay = None
    assert_equal(ov.overlay, None)
    ov.overlay = img
    assert_equal(ov.overlay, img)
    assert_equal(ov.filtered_image, img)
