Here I am going to explain the steps on how to use CropImage.Net tool to crop the images using Asp.Net.

In this demo I will upload a file and then the uploaded file will be shown in an image control. Then with the help of CropImage control the image will be cropped and shown in another image control called result.

First Step is to register the ImageCrop control in your page like given below

<%@ Register Assembly="Imazen.Crop" Namespace="Imazen.Crop" TagPrefix="ic" %> Then you need add the below CropImage control to your page and then set it Image property to the Image control from which Image is used to crop.

//Save the copy in local folder CropImage1.Crop(MapPath("~/images"), true); You also need to add the below configurations to your webconfig file

HTML:

<%@ Register Assembly="Imazen.Crop" Namespace="Imazen.Crop" TagPrefix="ic" %>

            Image1.ImageUrl = "~/images/" + filename;  
        }  
        catch (Exception ex)
