Bonjour,

Merci Lylejk

"isophotes" uses "isoline3d" :

Code: Select all

#@gmic isophotes : _nb_levels>0
#@gmic : Render isophotes of selected images on a transparent background.
#@gmic : Default value: 'nb_levels=64'
#@gmic : $ image.jpg -blur 2 -isophotes 6 -dilate_circ 5 -display_rgba
isophotes : -skip ${1=64}
  -e[^-1] "Render isophote maps from images$?, with $1 levels."
  -v - -to_rgba -repeat @# -l[$>]
    --luminance -repeat $1 --isoline3d[1] {$>*255/($1-1)} -done -rm[1] -+3d[^0] -col3d[-1] 1
    [0],[0] -object3d[-1] [-2],0,0,0,1,0,0,0 -rm[-2] -*
  -endl -done -v +
