Change RESOLUTION

[Sture Dingsoyr]

Hi

Is it possible to change the RESOLUTION of a produced image (e.g a
TIF/JPEG)?

The reason i want to do this is to be able to use the image for printing
prurposes...obviously a resolution of 72 is ok for use on the web
(screen). But if one wants to print the produced image on paper a higher
resolution wouldt have been great...

I try to set the RESOLUTION option in the MAP file...but nothing
happens...is the RESOLUTION option a constant set to 72?
