Hi,
I'm processing an image (please see attachment).
I tried to full fill the white rectangle (which is currently covered by the water drop shaped black shadow).
How can I remove the shadow to get the fully rectange?
I have the Boundary polyshape of white shape.
This is the polyshape I have:

Thanks

Create a vector between two points on the left edge above and below the drop, create a for loop for every row between column to the right to color it your chosen color. You can set additional paramters to limit how much is colored.

Use convhull or boundary to get contour of your figure
Then use inpolygon to fill this shape
