blur_bloom

Arguments:

• _amplitude>=0,_ratio>=0,_nb_iter>=0,_blend_operator={ + | max | min },_kernel={ 0:Deriche | 1:Gaussian | 2:Box | 3:Triangle | 4:Quadratic },_normalize_scales={ 0:No | 1:Yes },_axes

Description:

Apply a bloom filter that blend multiple blur filters of different radii,

resulting in a larger but sharper glare than a simple blur.
When specified, argument axes is a sequence of { x | y | z | c }.
Specifying one axis multiple times apply also the blur multiple times.

Default values:

amplitude=1, ratio=2, nb_iter=5, blend_operator=+, kernel=1, normalize_scales=0 and axes=(all)
