I would like to know the best way to create smooth round corners in one image (with different radius; from small up to half width/height) and make this corner transparent.

I found one procedure to draw a rectangle with rounded corners from Kieran Foster (December 7th, 2007), but as explained I need to cut the corners from image in a way that they are smooth and with a rounded shape. The part removed to create the round corner should be transparent.
Thx

On which kind of canvas do you want to draw ?
In a Timage ? a custom component ? Maybe the form itself ?

I ask this because of the "transparency" which is not achieved the same way in all cases. Forms shapes, for example, can have transparent zones thanks to "regions" that are cut out from the normal form rectangle.
For images, it is merely a specific color that is stated as the transparent color, so it is just a matter of painting the outside of the rounded corner with that color.
