Is there a tool that can automatically scale HTML image maps?

We have many imagemaps for a site in early implementation phase. Unfortunately, a design change requires that we change the physical display size of these maps... are th开发者_Python百科ere any tools that can automatically take the <map> data and scale the areas appropriately?

As far as I can remember, even FrontPage does this- when you downsize the image, it's image map is downsized, too. I believe the "SharePoint Designer" (available for free) must have the same feature.
