Rotate Images in Asp.net
 

Subject: Rotate Images in Asp.net

 

Here I will show you how you can rotate image in web page in asp.net

After clicking on button it will rotate and shown as:

 

.aspx code :

    <asp:Image  ImageUrl="~/H.GIF" ID="Image1" runat="server" />

    <asp:Button ID="Button1" runat="server" 

        Text="Button" onclick="Button1_Click2" />

 

Here I have taken one Image Control and One button.

 

.aspx.cs code ( code- behind page)

   protected void Button1_Click2(object sender, EventArgs e)

    {

 

        // get the full path of image url

        string path = Server.MapPath(Image1.ImageUrl) ;

 

        // creating image from the image url

        System.Drawing.Image i = System.Drawing.Image.FromFile(path);

 

        // rotate Image 90' Degree

        i.RotateFlip(RotateFlipType.Rotate90FlipXY);

 

        // save it to its actual path

        i.Save(path);

 

        // release Image File

        i.Dispose();

 

        // Set Image Control Attribute property to new image(but its old path)

        Image1.Attributes.Add("ImageUrl", path);

    }

 

 

// Hope you understand it.

 

Thank you.
