Refuse selection of certain colour?

[ddaddy]

Hi,
Is it possible for me to restrict the user from selecting the white corner if the picker?

Thanks

I've got this working simply by adding this code to -(void)onMoveSVIndicator:(UIPanGestureRecognizer *) recognizer

if (t.x < 145 && t.y < 95) {
return;
}
