Yes, the option layer defaults to -1 = all layers. If you use the cats or where option, you need to specify a layer, otherwise the warning

WARNING: No layer selected, 'where' and 'cats' options are ignored

Ah ha

Thanks,

Maybe an extra sentence in the manpage would be appropriate?

Under the "Description" section:

"If type=area is selected, boundaries of selected areas will be generalized, and the options cats, where, and layer will be used to select areas. However the cats and where options are used only if a layer is specified. If no layer is specified, those options are ignored."

Best, Micha

is issued in trunk. I have backported this warning to relbr76 in r74409.

HTH,

Markus M
