I think the problem occurs because the screen resolution of the user's syst=
em is different ot that assumed to be the default by Mapserver, and is rela=
ted i think to the dots per inch used to build and display the image (I'm s=
ure somebody else can supply all the technical details). I have found that =
to overcome this for our internal tools I add the following line to the map=
 file:
=20
RESOLUTION 96

Subject: [Mapserver-users] printing a map with a defined scale

hello world,
i would like to add a print function with a defined scale. The results i ob=
tain for the moment are bad and the scale given by mapserver is not the sam=
e as the document source. The mapserver printed map image (scale =3D 1/1000=
) is smaller than for example the same printed map with mapinfo (scale=3D1/=
1000).
=20
I hope this is understandable.
thanks=20
fx
