C#

private void menuItemUndo_Click(object sender, EventArgs e)
       {
           imageHandler.ResetBitmap();
           this.AutoScrollMinSize = new Size(Convert.ToInt32(imageHandler.CurrentBitmap.Width * zoomFactor), Convert.ToInt32(imageHandler.CurrentBitmap.Height * zoomFactor));
           this.Invalidate();
       }

The above code is used to do the undo operation only once in an image(c#).I need to work this function until all changes removed from the image.

So what you want?

Solution 1

you need to create a list of actions. Ideally you don't keep a single altered image in memory, you keep the starting image, and each time apply the actions in question. Then you just apply all your actions except the one you want to undo, to the original image, to get the undone one. The only alternative is to keep x images in memory where x is the number of undo steps.
