Local Vortecies by Indigo Ray

I would recommend you fix the typo in the title — it will be next to impossible to find this filter in the library.

Nice. Where was this when I was making GasGiantGen?

I have a small problem with non-squared images.

Hummm... So.... it can make seamless images, but it gets in trouble if the image is not squared, no matter if I choose seamless or not.
Changing the If settings to A=B, it works with non-squared pictures, but seamless doesn't work anymore.

This is not exactly the same as the problems found in the following threads, but read these about Bomber+ and the Particle Adapter. It is my opinion that this is related to the known issues with Bomber+ and non-square images.

Several links:
[Suggestion] Particle Cropping Warning is unnecessary for Bomber+
[bug] bomber+ has image aspect issues (Staff: By design)

I would post this as a bug. Very annoying and I don't think there is a workaround for your filter. The first clue that something is wrong is when you change the X/Y anchor in the final Rotate in your filter. If you put it on Image Bounds, it "mangles" the results.

Few things:

-You're right Ramlyn. Poor phrasing by me.

-I can add a bypass checkbox so that it works for any dimensions when seamless tiling is off. I don't think I can have the filter do it automatically.

-In FF, seamless tiling only works with integer aspect ratios. For example, a 300x600 image has a ratio of 2. This is more accurate than saying "square". A yellow warning box should pop up otherwise.

-I almost have it seamlessly tiling with other integer aspect ratios besides 1 (square). Almost.

-I don't think there is any bug here. But I feel like there could be a simpler solution, like an XY Anchor for the Bomber+ (which would apply to some of the slave components).
