Please add a property to disable the zoom witch CTRL+MouseWheel. Maybe something like IsMouseWheelZoomEnabled with a defaut value of true.

There are already other properties like IsPanningEnabled or ZoomToCursor.

The currently known solution is:

private void imageEditor_PreviewMouseWheel(object sender, MouseWheelEventArgs e)
        {
            if (Keyboard.IsKeyDown(Key.LeftCtrl) || Keyboard.IsKeyDown(Key.RightCtrl))
            {
                e.Handled = true;
            }
        }

In the Shape Tool - Line Shape -> lock ratio, this currently constrains the lines to be diagonal.

IMHO it'd be a more common use case that users would want to constrain a line to be horizontal or vertical.

I would suggest changing the default behaviour of the ratio lock for line shapes to be horizontal/vertical and not diagonal.

You could leave the Ctrl key modifier to still constrain diagonally, but add a Shift key modifier so that holding shift constrains the line vertically / horizontally (this would coincide with Photoshop behaviour).

I know it's not a great idea to change behaviour on published code, so could consider adding a LockRatioMode property to the shape tool that defaults to Diagonal, and allow coders to set it to HorizontalVertical to implement the new behaviour.

I just requested similar functionality for the Shape tool when drawing lines, and thought it would also be useful to have something similar in the Draw tool. I've raised a separate feature request because this one is for a different tool.

It would be good in the draw tool if holding the Shift key while drawing constrained the line to be horizontal or vertical.

In my use case people will load images and might want to underline things on the image.

Currently there is no way I can see to draw a perfectly horizontal line.

If in the draw tool you could hold shift and draw a perfectly horizontal line it would make this really easy and intuitive for the end user.

PS. To make the functionality more consistent with the Shape line tool, you could also add Ctrl as a modifier to the Draw tool to constrain the line diagonally.

Implement a command that opens a print dialog that allows you to print the image. There could be a print button in the RadImageEditorUI next to the "Save" and "Open" buttons.

In Shape and DrawText tools there are strings which are not changed if the current culture is changed during the lifetime of an application.

Using the built in OpenImageCommand functionality of telerik:RadImageEditorUI, you can detect the OpenImageCommand has been executed via the CommandExecuted event.

However there is no way to determine whether an image was loaded or not.

The Dialog Result is silently consumed by the OpenImageCommand class so if the user clicks the cancel button on the open file dialogue you have no way of knowing.

It would be good to have a means to determine the dialog result, either via a property on the command, by an additional property in the CommandExecuted event args, or even an event that is raised when an image is loaded or the dialog is cancelled.

To achieve this functionality I had to implement code like the following:

        public bool IsNewImage { get; set; }

        private void ImageEditor_CommandExecuting(object sender, ImageCommandExecutingEventArgs e)
        {
            if (e.Command is OpenImageCommand)
            {
                IsNewImage = false;
            }
        }

        private void HistoryOnCurrentImageChanged(object sender, EventArgs e)
        {
            var history = (ImageHistory)sender;

            IsNewImage = (!history.CanRedo && !history.CanUndo);
        }

        private void ImageEditor_CommandExecuted(object sender, ImageCommandExecutedEventArgs e)
        {
            if (e.Command is OpenImageCommand)
            {
                if (IsNewImage)
                {
                    // Deal with new image...
                }
            }
        }

It'd be so much easier to have the following:

        private void ImageEditor_CommandExecuted(object sender, ImageCommandExecutedEventArgs e)
        {
            if (e.Command is OpenImageCommand)
            {
                if (!e.CommandCancelled)
                {
                    // Deal with new image...
                }
            }
        }

Thanks 👍

The feature will be available in our official release 2015 Q2 .

The setting should be available in the settings UI, the DrawTextCommandContext and it should be respected in the DrawText command's Execute method.

Scheduled for: 
The feature will be available in R1 2019, scheduled for the mid of January 2019.
