How to define resolution (not dimension!) for IDLanRoi->computeMask [message #65057]

Hi all,

I'm stuck with the following:
I got a 2-dim image, say 256x256 pixels which spans (in real world
coordinates) the region from [1,1] to [5,5].
Plus I got ROIs defined on this image, say a rectangular ROI with x/y
coords [2,2], [2,4], [3,4], [3,2].

Now I'd like to have a mask for this ROI with the pixel dimensions of
the image.

roi = obj_new('IDLanRoi', .... real world ROI coordinates here )
mask = roi->computeMask( dimensions=[256,256], location=[1.,1.], ...
and now? )

Is there a way to specify the 'real world' size of the mask pixels
(i.e. 1 pixel = 1/64 cm)?

Cheers
Oliver
