Hello,

I'd like to rotate my TIFF image in my ASP.NET viewer via AJAX.

I'm using the invokeRemoteMethod but it doesn't seem to work.

Can you please give me some hints?

Thanks in advance.

My VB code:

Quote:

<Aurigma.GraphicsMill.AjaxControls.RemoteScriptingMethod()> _

Public Sub RotateLeft()

BitmapViewer1.Bitmap.Transforms.RotateAndFlip(Drawing.RotateFlipType.Rotate270FlipNone)

End Sub

My method call (JS):

Quote:
bitmapViewer1.invokeRemoteMethod("RotateLeft", null);

I'm sure the bitmapViewer is working. Because I'm also using some navigators in JS (something like the TIFF webdemo).

Hi,

I have prepared sample for you which allows to rotate tiff image. It works well for me. Please try to use it.

Code:

<%@ Page Language="VB" AutoEventWireup="true"%>
<%@ Register TagPrefix="aur" Assembly="Aurigma.GraphicsMill.AjaxControls" 
    Namespace="Aurigma.GraphicsMill.AjaxControls" %>

<script type="text/VB" runat="server">

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        BitmapViewer1.Bitmap.Load(Server.MapPath("test.tif"))
        BitmapViewer1.ViewportAlignment = Aurigma.GraphicsMill.AjaxControls.ViewportAlignment.CenterCenter
    End Sub
    
    <Aurigma.GraphicsMill.AjaxControls.RemoteScriptingMethod()> _
    Public Sub RotateLeft()
        BitmapViewer1.Bitmap.Transforms.RotateAndFlip(Drawing.RotateFlipType.Rotate270FlipNone)
    End Sub

</script>

            </tr>
        </table>
    </div>

        function RotateLeft() {
            var bv = $find("BitmapViewer1");

        }
