Transformation in Xamarin Carousel View (SfCarousel)
22 Aug 202221 minutes to read
The Offset between selected and unselected item can be customized in SfCarousel control. And also the items can be scaled to the specified value.
Tilt Non Selected Items
The RotationAngle property in the SfCarousel control is used to tilt all the unselected items in a specified angle.
NOTE
If the angle value is positive, then the rotation is in the clockwise direction. If the angle value is negative, the rotation is in the counterclockwise direction.

Set Gap between Items
The Offset property is used to specify the accurate distance between unselected items in SfCarousel panel.
NOTE
The default value is 20.

Set Gap between Selected and unselected Item
Distance between the selected item and other items can be customized by using SelectedItemOffset property of the SfCarousel control.

}Set Scaling for Carousel Items
The ScaleOffset property in the SfCarousel control is used to scale all the items to the specified scale value.

Spacing between the Items in Linear mode
Spacing of all the items in Linear mode can be determined by using ItemSpacing property.
