Heightfield Warp command-line

Software G'MIC
1

I don’t have a G’MIC GUI to copy the default parameters to the clipboard, for the Heightfield Warp filter.
Can somebody help in that regard and paste what you see as the default params from the GUI here? That could help immensely!

Thanks!

G’MIC command:
fx_heightfield_warp 1,“0.25cos(3pix)sin(3piy)”,100,0,1,1.5,nan,nan,50,20,20,40,30,20,1,“50,50”,50,50,75,50

From file update376.gmic:

Thanks!
So, it’s as I suspected, I kept getting the following error:

[gmic] *** Error in ./fx_heightfield_warp/ *** Operator '=' on variables 'heightfield_type,heightfield_formula,heightfield_factor,heightfield_smoothn(...)': Right-hand side '1,0.25*cos(3*pi*x)*sin(3*pi*y),100,0,1,1.5,80,20,50,20,20,40,30,20,15,50,50(...)' defines only 20 values for 21 variables.

But in the update376.gmic file it has: heightfield_type,heightfield_formula,heightfield_factor,heightfield_smoothness,align_camera_center,focale,light_x,light_y,ambient_light,diffuse_shadows,diffuse_highlights,specular_light,specular_material,preview_grid_overlay,preview_resolution,ocenter_x,ocenter_y,center_x,center_y,size_x,size_y=$1,"$2",${3-20}

The filter was only passing 20 of 21 parameters because of a wrong range (${3-20})
Updating it to ${3-21} made it pass everything correctly.

i.e.:
