Yes, it is possible:

Generally use this formula on all coordinates:

x_new = x_old + resize* (x_old - x_center)
where resize is computed in advance for each arrow based on maximum
distance between any 2 coordinates of the arrow and the required final
size of the arrow.

But you have to do some programming: Either mapbasic or export the table
to a MIF file and process that one in your favourite programming
langauge.

Subject: MI-L Resizing regions


Hi All

It is possible to resize a whole bunch of regions to a uniform size
without affecting the centroidal location and orientation or the region?


I have imported a whole lot of regions shaped as arrows from a water
modelling software.  The regions or arrows point to the direction of
water flow overland with velocity of water as attribute at a particular
point.

My problem is:  I want to thematically map those arrows according to
different ranges of velocity, no headache so far....however the arrow
shaped regions are of different sizes to represent changes in velocity.
To put it simply, is it possible to make all the arrow regions the same
size without changing the orientation of arrow shaped regions?

I thought about it, and I thought it maybe possible by defining a set
area size for all the regions....but I'm not really sure.  I don't have
mapbasic.

I would appreciate any help.

Cheers

Upinder.
