rep_shift_pixel_to_boundary_with_group_pixels_with_rectangular_polar_transformation

Arguments:

  • -1<=_fxy_position<=1,0<=_influence_factor<=1, _threshold>=0,-1>=_ptxy_xpos<=1,-1>=_ptxy_ypos<=1,'_channel_mode='

Description:

Apply rep_shift_pixel_to_boundary_with_group_pixels effect with rep_rectangular_polar_transformation

(equivalent to shortcut command rep_sptbwgp_recpoltrans).


_fx_position determines the location of pixel relative to ptxy points.
_influence_factor determines how much influence the effect have on pixels.
_threshold is used to eliminate alpha below the value.
_ptxy_xpos assigns the location on point of influence
_ptxy_ypos assigns the location on point of influence
_channel_mode is a special variable. See gmic h rep_sptbwgp for more information.

Default values:

_fxy_position=-1,_influence_factor=1,_threshold=0,_ptxy_xpos=0,_ptxy_ypos=0,'_channel_mode=N/A'
