    Copy image into a larger canvas.

    Examples:

    paste = dali.ops.Paste(
    # The image channels
    n_channels=3,
    # Historical values before mean subtraction
    fill_value=(102., 115., 122.),
)
paste_pos = dali.ops.Uniform((0., 1.))
paste_ratio = dali.ops.Uniform((0., 3.))
paste_prob = dali.ops.CoinFlip(0.5)

y = paste(
    inputs['x'],
    # Expand ratio
    ratio=paste_ratio() * paste_prob() + 1.,
    # PosX, PosY
    paste_x=paste_pos(),
    paste_y=paste_pos(),
)

    __new__
