Image cropping and image resizing with Xamarin.Ios

I need to implement image compressing and maintaining the aspect ratio with Xamarin.iOS. Right now I am using below code to show image from url.

uImage.SetImage(new NSUrl(imageUrl));

Above code is showing image from url. But images which are displayed are stretched without maintaining aspect ratio.

I need some code to maintain aspect ratio.

Solution

  • Set ContentMode of your UIImageView to

    • UIViewContentMode.ScaleAspectFill Scales the contents to fill the new bounaries of the view, while preserving the aspect ratio.
    • UIViewContentMode.ScaleAspectFit Scales the contents so that everything is visible, while preserving the aspect ratio.
