zoom point and zoom rectangle

[Steve Lime]

I believe it's used simply as a multiplier against the previous
cellsize. So, if the zoomfactor
is 2 then cells in the new extent will be 2 times larger, if -2 then
cells will be 2 times smaller.
That's how the CGI application does it anyway.

Hello,

Can anyone tell me how the mapscript function zoompoint uses the  
zoomfactor parameter to calculate the extent.

thanks,

boice
