I have a fairly simple image:
I'd like to change it to be wider at the ends like below, while still keeping the nice rounded shape:
The shape has solid gray colour, but its border is kindof transparent giving it a nice smooth finish, which I need to keep (as exact as it possible):
I think modifying this shape would distort the border, so I might have to redraw it, which seem an easy task with rounded rectangle. I just don't have an idea about the border, please give me some hints on that.
Reacting to comments (thank you!):
This is the original one's anti-aliasing:
I draw a rounded rectangle the way I want and anti-aliasing seems existing only on the rounded parts, and not on top and bottom straight lines:
