mapObj.scale

[Fabio Leme de Almeida]

Hello All,

 

I’m looking at Mapserver mapscript API.

 

The mapObj have a propriety called “scale”. At mapscript API manual, we have
the following:

“scale : float

The nominal map scale. A value of 25000 means 1:25000 scale.”

 

My question:

Supposing the map is scaled at 1:5000.  If I set initially the value to
10000, it means 1:10000 scale.

What’ll be drawn ? A Map with full extent ??

 

Other question:

Defining the scale with this propriety (supposing scale = 2000 and map scale
= 10000), when redraw the map, what’ll be drawn ?

 

Plus one more question:

Can I set the mapObj.scale value on the fly ? If I do this, what’ll occur ?

 

I’m using .Net C# with mapscript 4.10.0

 

Thank’s,
