How to create a seamless pattern from a seamless tile?

[Ric_NYC]

This is what I'm trying to achieve:
I've already created a seamless tile that is 4"x4".
From that tile I'm trying to create a square of 20"x20" that's also seamless in Xara.

So the final image will be a seamless 20"x20" square.

Squares with edges that don't have exact matches is what I'm getting now when I resize the tiles inside the large square.

The 20"x20" size is just an example, It can have different sizes (10x10, 30x30, etc).

Any suggestion is welcome!

I reckon your dimensions are wrong. Do check your tiles do not have a Line width.
Also use Snap to Objects.

This is the base tile, which is 2"x2":

This is what I get when I resize it inside the 20"x20" square. make a copy of the square and use snapping to put the 2 squares together:

The result is a non-seamless square.

You're definitely scaling something wrongly.

The base 2" x 2" tile is okay ... It doesn't seem to have a line width, although it does have a grey line on the left hand side, which comes through in the repeat.

Scaling this up to 20" x 20", you should get a 10 x 10 repeat so something is really screwy with your tiling/scaling. If you're resizing the base 2" x 2", then your resize is off somewhere.

For me it repeats like this at 8" x 8"

What were the steps you used to achieve that result? especially how did you resize the base tile inside the 8"x8" square?

the simple way to see if your 2 in by 2 in works is to set your program nudge to 2 inches, clone the tile and then nudge the clone - do they line up - they do, but as keith said there is grey line visible which is a flaw in the tile fill - also, the tile must not have an outline yours do not so that is ok

I would be tempted to build up the pattern this way and then crop it to the size I wanted

if you are syncing it to an existing square, make sure the square is fill only and no outline, use the coordinate x/y values on the select tool info bar as reference, that way you may not even need to snap

if you resize the tile itself enter actual [identical] values for hight and width, do not rely on percentages etc

I forgot to explain that I'm using the bitmap fill to create the pattern.
This is what I did:

1- imported the base tile
2- created a 20"x20" square (without outlines)
3- select the square and applied the bitmap fill as a "repeating tile" and used CTRL + image handles to resize the tiles while keeping the same width and length ratio.



I didn't use the method of snapping many base tiles to create a larger square.

I would not do that - I would make a vector shape the same size as the base tile [ eg copy the base tile and then intersect it with a larger rectangle]

I would apply the base tile to this vector shape, no need to mess about resizing and risking inaccuracy

I would then build up the larger shape in the way I mentioned before...

EDIT - forgive me you do not need to do the intersect - just do it with the base tile; in xara there is no difference between a bitmap filled shape and a bitmap

[handrawn]

like so - once you have done one row of horizontal base tiles, group it, then you can clone the row in one go and nudge down

I took the 2" x 2" tile and snapped copies to it originally.

However, just adding the 2" x 2" tile to the drawing anywhere: Draw 8" x 8" square: Add fill: Change fill to the picture bitmap: Change to repeating: Adjust fill handles: I cannot make the fill not seamless whatever I do. Using Shift I can distort it. but it's still seamless.
