I have an image of a circle with black boundary and it is filled with white colour. Now i want to fill white portion with red colour by mouse click.

Thanks in advance !

Black is black. Black can’t be tinted.

If you just set the image tint to red, it’ll be the effect that you want… unless the border isn’t true black.

You could place a red circle over the image in the place you want filled and enable the image when the mouse is clicked.
