Made An Animated GIF With An Ofnuts Script

[Tas_mania]

I got the idea from Jimmy Marco's 'Falling Snow or Other Brush' script. I made some transparent bubbles that worked with the falling snow script but I kept getting some frozen bubbles.

My solution was to make a canvas twice the size of the finished gif and use a soap bubble brush on a transparent background.

I then used ofnuts 'copy and shift layer' script to move each layer up about 36px. Rather than use the script on a base layer I used it to shift up every subsequent layer on the Y axis. So its shifting up a layer once and then shifting it up again once and so on.
I have no idea if this is how the script is supposed to be used but it works

Congrats. Always more than one way to skin a cat. Way to be resourceful.

Hello,

You have frozen bubbles using my script ?? ... shame on me !

Your idea is very good and interesting.

I will follow it.

Good continuation and have fun.

This is a scaled-down version of a short video clip made with Gimp.

The 'copy and shift layer' script is predictable using the double canvas size method.
When the animation is done I scale the canvas size down to half size. It's easy to do.

I would like the script to shift the layer last shifted automatically.

This is how the script runs. I had to do this 60 times to make the GIF above. It always opens with the last values so it's not too bad but I would like that part automated.

A better solution is on the way

Merci Monsieur.

Doesn't look right. Gravity should make the bubbles go straight up. But that would work for snow or leaves. Something like this example I made with Aviutl.

The "shake" is a setting. Now, if the glass in on your yacht's sun deck table and there is some swell, the bubbles won't go straight up.

Get `ofn-scroll-layer` from you-know-where.

[racer-x]

"ofn-scroll-layer" in google reports gibberish, wouldn't it be easier to post a link?

[ofnuts]

Just type "ofnuts" in Google and the first suggestion is the right one.

Otherwise: http://sourceforge.net/projects/gimp-to ... s/scripts/

Useful script, thank you Ofnuts

I wonder if it would be worth having an option for the user to specify a maximum number of frames produced? For example when the layer to be scrolled is more tiled less frames are needed.

e.g. for a layer of size image 640x480 with Step V -5 of course the script generates 96 frames.

But I made the layer a 2x2 tile, so only need 48 frames. I can get this by deleting the unwanted frames but that would be more awkward the more frames are involved.

(Minor point but the champagne images aren't showing in the ofn-scroll-layer.html page, think the filenames changed case).

The plugin looks good with excellent documentation. This is just the animation ofnuts made from the html.

I'm going to finish a gif I started with the old plugin before I start with this one. I suspect there is a new effect hiding in these plugins.

It's not easy writing a plugin that is used across multiple systems. Also in animation the eye seems to be drawn to any defect in the animation.
I've found bubbles are easy because the beginning and end can just be a space in the 'flow'.

Hi teapot. You started all of these rising bubbles The following deletes every second file either even or odd numbers on linux:

Code:

rm -f *[13579].png

Code:

rm -f *[24680].png

Note. If you use the top one then file 2 becomes file 1 after you re-number. Running it again would delete 2 files in the series. That means alternate between these and re-number if removing multiple files.

Give a max number, no, but a pair of tiling factors, yes.

As far as I can tell they have matching cases in the ZIP and in the HTML (I'm on Linux, so case-sensitivity of file names is a fact of life). The final animation is a WEBP image that is supported in decent browsers.

[ofnuts]

Updated with support for tiles.

[Tas_mania]

Maybe this should come with some sort of health warning?

This started as 400 frames and I reduced it to 200, then 100 using the method above.

Tas_mania, I'm going boggle eyed

Thank you

Thanks, it was me mucking up my directory

Cleverly done

Hi ofnuts.
I found a problem using the scroll-layer script. I would like to animate this image horizontally.

With settings of 1 horizontal step and 1 horizontal tile I get 3840 layers at 87Gb image size. That's too big for my computer to use. Is it possible to get less layers? The script works OK with animated GIFs but I like making 1280X720px images for video.

[ofnuts]

Your image is 960px (zoomed at 25%, so 3840px wide). If each frame is shifted 1px, you need 3840 frames for a full cycle... if you had less frames the animation wouldn't be continuous. If you want less frames use a bigger step or a smaller image o( tile the image). Note also that the layer is much taller (4x) than necessary... this costs you RAM.
