[Inkscape-user] How 2 mask an arbitrary object with a grid of only whole smaller objects?

Hi,

I'm moving over to Linux & Inkscape from Windows & Adobe.

I'm working on learning the tools and methods in Inkscape. Got a lot of it figured out. Pretty similar actually.

I do have a test case that I'd appreciate some help figuring out:

Given an arbitrarily shaped object, how do I mask out a tiled pattern, using only complete tile objects?

So for example, starting with

(1) main object is a red, 8inch diameter circle (2) mask object is a black, 1inch square

I want to mask (1) with (2), so I end up with a bunch of complete (no clipped, or partial) 1inch red squares on a grid, contained inside the boundary of the original 8 inch circle.

I've figured out Tile Clones, so I can manually make a grid of mask objects larger than the original object.

I guess I'd put together two layers -- one with the original and one with the mask later -- and intersect them.

Is there a way to do this in (more?) automated fashion providing the sources only for (1) & (2)?

Cheers,

Jim
