I have a number of complex shapes (for example a sketch of a gecko, an ant and a frog) and want to colour a defined fraction of the area of each sketch from the bottom, e.g. 20% of the gecko in blue, 30% of the ant in red etc.
As an illustration, I uploaded two example shapes:
The rectangle on the left has 20% of its area filled from the bottom, which is easy enough to do. For more complex shapes, however, as the one on the right, it is less trivial. Is there any way to do this in inkscape?
Thanks!
