Just put a `return 1.0` for `Alpha = 1` or whatever value you want. — Ahmed Z., May 22 '13 at 07:50
@NitinGohel .. Use this, it will work as per your need.. Just change the alpha value in the return statement to your own alpha value you need. — Ahmed Z., May 22 '13 at 07:51
@NitinGohel You just need to put 1 line `return YOUR_ALPHA_VALUE` in the method `-carousel:itemAlphaForOffset:` — Ahmed Z., May 22 '13 at 08:05

There are various ways to achieve this. The carousel:itemAlphaForOffset: answers you've already received are a good approach, but they'll involve doing a bit of maths.

If you have a recent version of iCarousel, you can implement this more easily using the options API. Add this method to your UIViewController (if you are using the example project it may already be in there and you'll need to modify it):

- (CGFloat)carousel:(iCarousel *)carousel 
     valueForOption:(iCarouselOption)option 
        withDefault:(CGFloat)value {

    switch (option) {
        case iCarouselOptionFadeMin:
            return 0;
        case iCarouselOptionFadeMax:
            return 0;
        case iCarouselOptionFadeRange:
            return 2;
        default:
            return value;
    }
}

You can replace the 2 with a bigger or smaller number to increase or decrease the opacity of the side views. For example, a value of 3 will make them less transparent. A value of 1.5 will make them more transparent. (A value of 1 will make them invisible).
