Could someone please tell me what is the general logic for a zoom-in, zoom-out web module? It doesn't just double the size of say a gif to zoom-in 50%, does it?
The ones I've seen on the web just occupy about a quarter or third of the page, so there must be something complex about the procedure.
For example, imagine a map of Florida covering at least 7/8ths of the whole screen. One can make out "Orlando", and all but the big cities are illegible. The person wants to zoom-in to the Orlando area to see in detail the roads around it. In general, what is the logic for doing this??? Remember, all zoom-ins and outs must occupy at least 7/8th of the screen (leaving room for the logo.) Could this be done in a non-Java language, maybe Perl and what would the general logic be? (In this particular case, a horizontal scroll would be ok.)
Thank you very much.
