When we are trying to crop the image when CanvasMode is set to "No", Instead of the position from where the image must be cropped, it is cropping the image from coordinates (0,0) i.e. from the top left corner.

Also, we are getting the issue in only some of the files. We are able to edit other files.

Is it possible to place form controls, eg Signature control, tick boxes,etc.. in RadImageEditor?

When the page is zoomed in iOS and Android devices, lines drawn are displaced downwards and to the right. Displacement increases with image zooming.

Configurations tested:
- iOS + Safari;
- Android + Chrome;

When the command dialogs from two ImageEditors on a page are opened consecutively, the second dock is rendered with wrong position. The issue most probably comes from the fact the second dock element (ToolsPanel) is appended to its parent ImageEditor, but not to the form.

Assuring that each dock is appended to the form element can be used as a temporary workaround of the issue:

        <telerik:RadImageEditor ID="RadImageEditor1" runat="server" Width="680" Height="450" OnClientDialogLoaded="ClientDialogLoaded"
            ImageUrl="waterpool.jpg">
        </telerik:RadImageEditor>
        <telerik:RadImageEditor ID="RadImageEditor2" runat="server" Width="680" Height="450" OnClientDialogLoaded="ClientDialogLoaded"
            ImageUrl="waterpool.jpg">
        </telerik:RadImageEditor>
        <script>
            function ClientDialogLoaded(imageEditor, args) {
                setTimeout(function () {
                    $telerik.$("#<%=form1.ClientID %>").append($get(imageEditor.get_id() + "_ToolsPanel"));
                }, 0);
            }
        </script>

In the latest release (Q1 2016) it is possible to resize and drag the crop box in ImageEditor to negative bounds in IE.

Dialog tools panel is not positioned properly when there are more than one ImageEditor on the page. The dialog shown from the second ImageEditor is rendered below the control (on the bottom of the page), outside of the browser viewport.

JS error is thrown when opening a tool in Lightweight and ShowAjaxLoadingPanel="true".

Error message:
Uncaught TypeError: Cannot set property 'id' of undefined
     at Telerik.Web.UI.RadImageEditor._showAjaxLoadingPanel


Steps to reproduce:
1. Run the following code
            <telerik:RadImageEditor ID="RadImageEditor1" ShowAjaxLoadingPanel="true" runat="server" RenderMode="Lightweight" ImageUrl="~/Images/Summdary.jpg">
            </telerik:RadImageEditor>

2. Open the "Crop" dialog

Result: A JS error is thrown.

JS error is thrown when a Responce.Redirect() is made after editing an image in RadImageEditor.



Steps to reproduce:

1. Run the following code:

        <telerik:RadImageEditor ID="ImageEditorControl" runat="server" RenderMode="Classic"
            Width="790px" Height="430px" ImageUrl="~/Images/bhp-500l.jpg">
        </telerik:RadImageEditor>
        <asp:Button ID="Button3" runat="server" Text="Redirec" OnClick="Button3_Click" />

    Protected Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
        Response.Redirect("https://www.google.bg/")
    End Sub


2. Open the Pencil tool and draw something on the image

3. Click the Redirect button

Result: A JavaScript error is thrown.

A large uploaded image is not saved properly after cropping in disabled CanvasMode. Instead of saving the cropped part of the image, the control is saving the original image resized to fit the cropped part size.

The issue is reproducible both by using the Save dialog (Save image on server) or the saveImageOnServer() method.

Steps to reproduce:

1. Open http://demos.telerik.com/aspnet-ajax/imageeditor/examples/imageupload/defaultcs.aspx in IE8
2. Upload the attached image
3. Crop a part of it
4. Save the image on server

Result: The original image is resized with the crop-box dimensions.

The Classic RenderMode displays the Crop icon for custom tools, the Lightweight RenderMode displays a gear icon

Workaround:

			/*set background image*/
			.rieSomeCommandName
			{
				background-image: url(my-images/icon_16x16.png) !important;
			}
			/*add for lightweight render mode*/
			.rieSomeCommandName.rtbImage::before
			{
				/*set your own font and/or content if you want to use a font icon instead of a raster image*/
				content: "" !important;
			}

where the command name is taken from the tool by concatenating rie + <command name>:

			<telerik:RadImageEditor runat="server" ID="RadImageEditor1">
				<Tools>
					<telerik:ImageEditorToolGroup> 
						<telerik:ImageEditorTool Text="some text" CommandName="SomeCommandName"
							ImageUrl="my-images/icon_16x16.png"></telerik:ImageEditorTool>
					</telerik:ImageEditorToolGroup>
				</Tools>
			</telerik:RadImageEditor>

The mouse position coordinates of the ImageEditor (can be seen in its bottom Statusbar) are not updated properly after zooming (Crtl+Mouse scroll over the image). Moving the mouse pointer outside the ImageEditor's viewport and bringing it back forces the control to recalculate the mouse position properly.

Video: http://screencast.com/t/BB7UzCwj0zz

Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/imageeditor/examples/overview/defaultcs.aspx
2. Choose a specific point of the image and check its position (the x and y coordinates shown in the ImageEditor's status bar)
3. Zoom-in the image by pressing Ctrl and Mouse scroll
4. Navigate to the same point

Actual: The x and y coordinates are changed
Expected: The x and y coordinates of the point are the same as before the zooming

Filtering operations are registered twice in the undo stack of the ImageEditor.

1. Open http://demos.telerik.com/aspnet-ajax/imageeditor/examples/toolbarmodes/defaultcs.aspx

2. Click on the More arrow on the right most on the Toolbar

3. Click to expand the Brightness/Contrast split button and choose Greyscale

Result: The Greyscale command is added twice in the undo stack of the control

For the time being you can hardcode the "touch-action:none" style to the ImageEditor:

<telerik:RadImageEditor ID="RadImageEditor" runat="server" style="touch-action:none;"></telerik:RadImageEditor>

When you set Lightweight render mode via web.config, the image editor appears broken.

You can use the following setup in web.config as a workaround for the time being. Note that all instances of the RadToolBar will be rendered in Classic mode.
 <appSettings>
      ....
      <add key="Telerik.Web.UI.RenderMode" value="Auto" />   
      <add key="Telerik.Web.UI.ToolBar.RenderMode" value="Classic" />
       ....
</appSettings>

When the cropping box is resized through one of its left corners, the position of the cropping box is changed at all. The issue could be reproduced in all browsers. http://screencast.com/t/PDns6kPb
