Yes.

，但这与ASP.NET无关.它是用Javascript完成的.例如，请参见 http://stevehanov.ca/blog/index.php?id=93 [ ^ ].

Certainly, but it''s irrelevant to ASP.NET. It is done in Javascript. For example, see http://stevehanov.ca/blog/index.php?id=93[^].

Even if you can develop server-side processing for mouse events with re-rendering of the image, it would be too slow to work.
