I remember the very first version i believe was one of the first time i posted in a gimp forum, i was badly missing in gimp a virtual mirror and then Saulgoode come with a perfect soluction, that mirror script

Well back to the present and to the point

would be possible change the input/output options of the script ?
i would need

FOR INPUT
not only the active layer but all layers mirrored,
with same setting by the same call
OUTPUT
all the mirrored layers in 1 new image.

That script rocks!

Example?

from a image with 10 layers i would like a new image with 10 layers, all mirrored with same setting.

basically a added option to use for input all the layers, left the original image unmodified, and output a new image

But if all the layers had the same setting, wouldn't they still overlap each other? Or are you planning on manipulating those layers after the effect is run? Otherwise, you need the image size to enlarge to accommodate the effect. I think I know where you are going with this, just not entirely certain of how the result should be. Just curious.

After running the script you could just move the objects around on their layers.

ROD & Saulgoode

i explain better

I am finishing a animation each image is a frame each with several layers all layers have transparency (except the BG )

example ( usually there are 4 or 5 layers,i used here only 2 to simplify )

1 layer of the first image



mow i add another layer on top , and this the visible of the first image


i say are frames, in each image layers are more then 2 all rotating along same center but with different speed and direction
anyway i need to mirror all the layers in each frames so this woulf be the correspondent still.



but remember that along the frames each layer rotate with same center, but different speed and direction
Then mirror each layer allow
1 to multiply image size without loosing quality
2 to multiply the centers of the moviment mantaing a perfect simmetry

mirror only the visible of each frames will be somehow limiting (in the mirrored frames i would like be free as final post work to offset layers modify their transparency and color ...

i am looking now in gmic , maybe some option of "mirrored array" may solve

BTW Rod the original was the vector looking bee you posted recently

Do all layers share the same dimensions as the image?

yes

You mean, Mahv? Hehehehe. I posted the bee. And yes, I thought this was your intention, so you do want the image size to accommodate the mirrored action of all layers. Cool script idea.

yes it was your i modified a bit

I am tryng to make a video tutorial for 3D looking kaleidoscopic animation.
the basic idea is
1 found a good source should have large transparent part.
source image should have large transparent part, and should be rectangular largest side should be at least 1.5 bigger then smallest


2 duplicate several time the source
3 apply kaleidoscope with different setting on each layers,
taking care to reduce overlapping of transparent area
4 add a soft drop shadow at each layer
5 rotate each layer as required for each frame
6 from the center crop the square (large as smallest side of the rectangle )
7 now all layers have same size and position

8 Here i must mirror all layers in both directions

final postwork just some panning and zooming and the final crop at 16:9

That sounds awesome.What a cool idea for an animation.
I even know how you could make them go in dif directions.

If you mean to create an animation such as the following then I would recommend using the GAP.

Not exactly that:
the movement in your example is not mirrored only duplicated (well quadruplicated )

If the first thing move clockwise the next should be horizontally mirrored so should move anticlockwise

and the 2 below should vertically mirror what on top...your example look more as a array then as a mirrored array ...at least for the movement

Maybe i found how solve without a script...i am testing now

Still should be easily doable with GAP. After you have one animation (a sequence of multi-layer frames), flatten the layers and use plug-in-small-tiles to mirror and duplicate them (Small Tiles permits mirroring).

that may be the right direction

the problem is that i would like avoid to flatten layers to be able to apply some final postwork on the mirrored layer

But i suppose i may well use map tiles on the layers (running with GAP frame modify/apply filter on layers for the first layer of each frame ,then for the second...)

i fear some offsetting but maybe is just a paranoia

I can't use Gmic, even if has a filter that should do that, and even adapt option for I/O:
often gmic "mirrored array" add white stripes to the merging lines, edit that white lines for a lot of frames would be a nightmare

That should be possible with GAP (though I did not try it). Just use "all visible layers" for your layer selection in the first Frames Modify dialog.

thank i will try

I'd prefer a script over GAP. GAP seems too far complicated to use straight out of the box, and I am guessing its why a lot of people choose not to use it.

PC: If you don't mind, if you do use GAP and like your result, would you mind sharing the process with the rest of us. I'd love to be adventurous and pursue this myself, but unfortunately, I have to pick my projects according to my skill sets. GAP isn't a part of that.
