namespace MyStuff.App_Code
{
    using Umbraco.Core.Models;
    using Umbraco.Web;

    public static class MyHelpers
    {
            public static string MyGetCropUrl(this IPublishedContent publishedContent, int width, int height)
            {
                var bgColor = "fff";
                return publishedContent.GetCropUrl(width, height, furtherOptions: string.Format("&bgcolor={0}", bgColor));
            }
    }
}

MyView.cshtml

@inherits UmbracoTemplatePage
@{
    var a = Model.Content.MyGetCropUrl(100, 100);
}

No problem.

That would be a string extension method which you could do but why when you already have the IPublishedContent object?
