Erreur lors de l’exécution de script-fu-advanced-tone-mapping :
Error: Procedure execution of plug-in-gauss failed on invalid input
arguments:
La procédure « plug-in-gauss » a été appelée avec la valeur
« 906,390000 » pour le paramètre « horizontal »
(#4, type gdouble). Cette valeur est hors-limite.
Any hint to correct this problem?
If one looks at advancedtonemapping.scm
it invokes Gimp's internal procedure plug-in-gauss which has limit of
500 for the blur radius.
I think, 500 is quite a lot.
But advancedtonemapping calls it with a blur radius of
blurAmmount*(width+height)/200
When you invoke advancedtonemapping from within Gimp the first entry is
Gauss. Blur (% of img size):
Unfortunately, the default value is 10, the minimum you can enter is 1.
and with your image you have
width = 14903 height= 5239 which gives
blur_radius = blurAmmount * 20142/200 which is approximately
blurAmmount*101
So, to meat the restriction imposed by plug-in-gauss you have to set
the blurAmmount to 4, at most.
If you need more fine grained control, you'd have to modify the file
advancedtonemapping.scm, e.g. by replacing the line
(car (gimp-drawable-height theLayer))) 200))))
by
(car (gimp-drawable-height theLayer))) 2000))))
and
SF-ADJUSTMENT _"Gauss. Blur (% of img size)" '(10 1 100 1
10 0 0)
by
SF-ADJUSTMENT _"Gauss. Blur (%o of img size)" '(10 1 100 1
10 0 0)
i.e. the entry is taken as parts per thousand.
