How to create a seamless pattern from a seamless tile?

[Acorn]

The base tile that you used must have been changed by the website I used to share the image. If you take a look at the last picture that I posted you can see that inside the large square, there are no lines.

Thank you, guys!
I'll read all the posts again and try to figure out what I should do!
I knew that snapping the base tiles could work but I was trying to use a feature that's built-in (the repeating pattern option).

I tried your tile again and it was clean without the edging.

Here is my approach for 1x1, 3x3, 10x10, 20x20: Seamlessly.xar

and it carries on past the flower:



now I am fussy, in animation you have to be, maybe this does not matter to Ric and accepting this, it still tiles ok for me and for others....

Lines in patterns are an old bug that's been around for years. That's a distraction from my question.

The lines may be a bug or the quality of the base tile, but that's not what I'm asking here.

lines - yes it's an anti-alias thing - best to work in open GL - or in xara in 'full colour' view quality if you want to avoid it - that is not a bug, it is a consequence of how renderers work - I can make it work that way without issues in harmony

as for the question, that has been answered in this thread regarding seamless tiling in xara has it not ?

[Ric_NYC]

I used an old program called Patternshop to explain what I was trying to do in Xara.


1- In this image, you see the base tile and 2 patterns created from that tile. The 2 patterns are exactly the same

2- When placed together the 2 patterns (A and B) are seamless:

That (#2) isn't seamless.
You have a small seamless tile, why are you trying to create a large seamless tile from it. It's causing issues that shouldn't exist.

[Ric_NYC]

I don't see the lines between tiles in Xara. It happens when the file is exported as a PNG.

It's a famous old bug that's been around for many years in images created in Illustrator and Inkscape etc. I called it a bug because I don't think it can be called a "feature".

That can be fixed by changing the settings in Illustrator.


The bug is shown in this video:

Ric, I think you're missing my point. You have a perfect small seamless tile, no joins created by misplacement, anti-aliasing or anything else. Nothing to do with creating a perfect seamless tile. Having done that you seem to be messing them up creating larger seamless tiles that don't tile seamlessly.

Then just cut your tile in Xara with a 0px line width or a shape with no line.
Always set the the dimension to be whole pixels, 2" = 192px, which is fine.
