[GRASS5] i.pca and masks

I did some PCA on images using different masks and only then I noticed
that in the end I got the full image, without a mask. However in the man
page it says:

The current geographic region definition and mask settings are respected
when reading the input raster map layers

What does this mean? That it uses the mask only for making the pca
calculations, but then shows up the whole image?
If I would want to build up a image on the mask area (hard disk
space...), would it be possible?

Thanks,
