[Mapserver-users] rectObj->fit()

[Steve Lime]

That method takes an extent and 'fits' it to a particular image size.
The input parameters are the hight and width of an image. What's
returned is the cellsize (in map units) of the resulting extent and
image.

I'm having trouble understanding rectObj->fit().  What are units are 
the input arguments?  I figured they'd be in the units of the map.  For 
instance, I'd like to grow a given rectangle by 1000'  So I'd think I'd 
do something like:

$x = $rect->fit(1000, 1000);

What is the double that's returned?  I thought that might be the factor 
I would grow or shrink the original rectangle.  Would someone help 
please ... maybe post some example code?

Thanks.
