rep_edgefade

Arguments:

  • radius>0,_exponential_factor>0    or
  • radius>0,_exponential_factor>0,_nl_amplitude>0,0<_n_smooth<=1,0<_a_smooth<=1

Description:

Fade edges on alpha. Only applicable for images with 2 channels or 4+ channels. The last channel is the alpha channel.


Note: Execute gmic h normalize_local for more information on _nl_amplitude,_n_smooth, and _a_smooth. nl is short for normalize_local.

Default values:

_exponential_factor=0,_nl_amplitude=0,_n_smooth=4%,_a_smooth=5%
