[mapserver-users] confused about using zoomRectangle

[Ahmet Temiz]

hi,
thank you

I had tried two ways you mentioned as 1 and 2

"1" is rectObj(10,10,100,100,0)
"2" is rectObj(10,100,100,10,0)

both resulted exception.

what I want to know is that if I can create any image box providing keeping the same size.

I mean rectOb(11,11,101,101) and rectOb(12,12,102,102) and so on have same effect
on zoomRectangle.

regards
