is there change remove or resize selected object canvas without changing other design.

for example:- drawn circles (just circle1, circle2, circle3) . circle1 bottom of other 2 circles. want remove circle2 or re-size. should not effect other circles.

and there change without using clear canavas method.

it should work powerpoint design draw , resize , delete.

i not think possible, canvas bitmap object far know , draw on updates image.

if use circle object should svg
