Image scaling,make it it fit to bounds of UITableView cell with maintaining color combination and image quality in monotouch

Problem:

I have used following code for scaling image and make it fit to bounds of UITableviewCell in monotouch.This code is scaling image but it is making image color faint means it is not maintaining color combination.So please provide any better solution.

Code:

public static UIImage Scale (UIImage source, SizeF newSize) { UIGraphics.BeginImageContext (newSize); var context = UIGraphics.GetCurrentContext (); context.TranslateCTM (0, newSize.Height); context.ScaleCTM (1f, -1f);

        context.DrawImage (new RectangleF (0, 0, newSize.Width, newSize.Height), source.CGImage);

        var scaledImage = UIGraphics.GetImageFromCurrentImageContext();
        UIGraphics.EndImageContext();

        return scaledImage;         
    }

If you want scale UIImage, then see this method. It works fine. You should cache method's result in file system to avoid image scaling on every GetCell.

If you source images are the same or almost the same size like UIImageViews in UITableViewCell Mohib Sheth solution with setting ContentMode property is best. It source image have much greater size than UIImageViews in UITableViewCell, scrolling speed will be lower.

Read all about ContentMode for UIView in iOS here

For your requirement you would need to set the ContentMode property to UIViewContentModeScaleAspectFit

I cant help you with a sample code, since you haven't provided any code on how you are creating & populating the TableView.
