[script] resize image in pourcent

[Didier BRETIN]

Hi,

I'm improving my script, and I would like to use the function
gimp-image-scale and specify widht and height in pourcent, not in pixel.

Do you know how I can specify pourcent ?

Regards.

You need to calculate the pixel values manually.

(gimp-image-scale image
                   (* (car (gimp-image-width image)) x-pct 0.01)
                   (* (car (gimp-image-height image)) y-pct 0.01)
                   )
