A Bounds
element is an box shaped annotation that is specified as a tuple in (left, bottom, right, top) format:
penguins = hv.RGB.load_image('../assets/penguins.png')
(penguins * hv.Bounds((-0.15, -0.4, 0.2, 0))).opts(
opts.Bounds(color='orange', line_width=6))
It is useful for denoting a region of interest defined by some bounds (such as a slice) which is unlike the Box
element which is useful for drawing a box at a specific location. Here we show the a slice of the RGB
element (green channel only) outlined by the bounds. Note that the values in the Bounds
tuple are the same ones as used in the slice:
penguins * penguins[-0.15:0.2, -0.4:0, 'G'] * hv.Bounds((-0.15, -0.4, 0.2, 0))
