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
Hi,
the simplest way to do that is to convert your square to a pattern (object->pattern->object to pattern); then it will appear as a pattern in the fill and stroke panel, and you can use that as a fill for your circle.

I tried that.
The pattern does fill the circle but it gets clipped by the circle, too. So I end up with clipped/partial squares. I want to end up with only WHOLE squares ; if one would be clipped, it'd not be used.
Also, the resulting doc's pattern squares are not then individually selectable. I should've added THAT as a 'wanna have' to my original post.

Oh, sorry, i missed the "no clipped" part.
Did you try the "trace" tab in the tiled clone dialog (take opacity, gamma-correct -10, apply to presence) ?
The opacity under the clone square will be used to give a probability of presence to the clone (so, if you have a filled opaque circle, "1" for squares inside the circle, "0" for squares outside, and in between for circles on the edge, the -10 tweak ensure there are as few as possible left)

I selected the square, setup to create a 10x10 grid of tiled clones, with the "trace" tab settings as you suggested.
I grouped the tiles, sent the grouped object behind the circle, then selected clip/mask. I end up with a circle filled with the clone squares -- still *both* whole & partial.
Not sure if I missed something :-/

There's *TWO* opacity checkboxes in the dialog!
Checking them BOTH, this is the result I get now
It's a lot closer, but I still have a couple outside-the-bounds clone tiles.
Also, those individual clone tiles inside the circle can't be selected / edited. Maybe I need to export the result first; have to figure that out.
Cheers,
Jim
