where to place mouse point in Paint application with command pattern

I'm writing paint application in javascript (typescript)

my Command interface is showed here:

export interface IUndoableCommand extends ICommand {
    GetUndoCommand(): ICommand;
}

export interface ICommand {
    Process(surface: ds.ICanvas): void;
}

so each command receive an ICanvas interface which let this command manipulate pixels of image.

My question is, According with this command, where should I put all the time changing mouse points to let the command know where it must draw?

1. Instantiate new command each time mouse cursor position changed?

2. When instanting new command object, maybe I should pass lambda expression such as this:

   new DrawRectCommand(() => ut.Point { return Mouse.GetCurrentMousePoint(); }, () => ut.Point { ... });
   
   

I fell it's more general problem becouse I would need pass more point's than the current one. But how to do it properly?
