We’re also setting the Model.Top, model.left, Model.Right, and Model.Bottom properties to the html form values being automatically set by jCrop. Jcrop on our profileImageEditor image tag, setting the jCrop onChange and onSelect callsback to the showPreview function. marginTop: ‘-‘ + Math.round(ry * coords.y) + ‘px’.marginLeft: ‘-‘ + Math.round(rx * coords.x) + ‘px’,.height: Math.round(ry * height) + ‘px’,.var width = var height = var rx = 100 / coords.w.Next, we’ll need to add some javascript in a script tag at the bottom of this view: These we pass back to perform the cropping operation. We display our editor for the image, and create hidden HTML fields for the Left, Right, Top, and Bottom properties of the cropping indicator. using(Html.BeginForm( “Edit”, “WebImage”, FormMethod.Post))įirst, we’re referencing our jCrop css and javascript files, alogn with creating the form for passing back our cropped image values.We’ll create an Editor input model that will give us the ability to both supply those values, and to retrieve the final cropping dimensions to perform the cropping action. JCrop requires a few image properties initially to set the initial crop window. Lets fix this problem by giving our users the ability to crop their image using jCrop. this causes most images we’d upload to appear tiny and squished. In our app, we’re displaing a profile picture constrained to a 1 to 1 aspect ratio. We then retrieve the image url and set it back to the ImageUrl property of our ProfileViewModel instance and return the model to our view. We the get the filename and use the Save function of the WebImage helper to svae the file to a TempImages folder. Since we’re constraining all images to a maximum of 500 pixels in width, we’ll use the Width property to check the size, and use the Resize functionality of the WebImage helper to resize the image in memory. Using the GetImageFromRequest static method on the WebImage class, we retrieve a WebImage object representing the uploaded file. model.ImageUrl = Url.Content(filename).filename = Path.Combine( “~/TempImages”, filename).image.Save( Path.Combine( “./TempImages”, filename)).var filename = Path.GetFileName(image.FileName).var image = WebImage.GetImageFromRequest().public ActionResult Upload( ProfileViewModel model).We’re creating a very simple solution for displaying and cropping images here.įirst, we’ll need a view model for our profile editing view. Also, include the package included with ASP.NET MVC 3.

We’ll explore how to quickly and easily create a solution using ASP.NET MVC3 and 2 of the new Razor helpers, the FileUpload and WebImage helpers and jCrop, an excellent jQuery plugin for image cropping. The implementation of image cropping functionality has traditionally been somewhat cumbersome for developers, and users are generally pained by having to crop an image offline before uploading it, especially more inexperienced computer users. In many cases, this can be a bother for both user and developer.

Note: If you get a “Project Type Not Supported” in Visual Studio 2010, you need to download the MVC 3 Tools Update (or install SP1, I believe).Ī common requirement for websites that allow user registration is the uploading of user profile images.

I somehow miraculously stumbled upon the source code for this project, so I’m including a link to it here:
