I like it a lot!!! Thanks teapot

Cool Teapot

Very nice teapot!
Let me guess, did you strike a path with a brush where dynamics is color from gradient, then your script/tuto?
I'm thinking to wake up the thread "Decoding your text"

I've been thinking about it, PixLab like you. But my try has been a failure. My path wasn´t good enough.

Thank you for your nice comments Sallyanne, Issabella and PixLab.


Yes that's right

My steps were:

Make a path.

Select the 'Pastel Rainbow' gradient.

Select brush '2. Hardness 100' but other brushes work too so long as the spacing is quite small, I used spacing 10.
Brush dynamics 'Colour from gradient'.
Repeat 'Sawtooth wave'.

On a transparent layer, stroke the path with:
Stroke with a paint tool.
Paint tool: Paintbrush

Python-Fu -> Rotate Hue
Step 20

Add a background layer to each frame, save as an animation.

Variation with a different brush, and dynamics:




You could just use text to path and have the letters outlined
Or there's the font paths Skinnyhouse posts:

Amazing animated text effects since Teapot's post#889.
Congrats to everyone who had such skill and patience.

Thanks teapot for a good description of this effect. You didn't mention to use a joined-up font

Your rotatehue script gave me the idea to use the hue slider in 'Hue-Chroma'. That is a GEGL import so is hard to script but I had a batch script that I modified to apply the -180 to + 180 range on an animation series.

I realized that starting and ending at 0.00 meant it could be used as a video transition that colorizes parts of a clip.

Thanks teapot

Good point I made the path have just one stroke by joining up the letters by hand, but anything goes including just drawing with a paint tool:



'Hue-Chroma' gives a different result to 'Hue-Saturation' so how do you choose which to use?

I'd like to call 'Hue-Chroma' from python but don't know how, I think there maybe some threads on calling GEGL from python. How do you do it from your batch script?

That sounds cool

Ella, Thanks for trying it out I'm loving the teapot

diagrajamal1, very nice kaleidoscope effect

It's very strange but in some recent examples I can't read the text

@Teapot
Glad you posted your plugin.
I have two minor comments about it:
- for animation plugins it should be possible to specify the number of frames (so steps=360/frame



- location in the menu: why not more adequate:
"<Image>/Filters/Animation/Animators"

Regarding Gegl (the hardest first step)

(for the convenience of users, I paste this code into every plugin that uses GEGL - and it is required for Windows)

In your plugin you just need to replace the line:

Quick comparison saturation & chroma:

Hi MareroQ
Nice idea to change the menu path, but in my humble opinion, adding "Animators" as a sub-sub-sub menu is becoming too long, I already did a change on the one I did downloaded, I did put it directly in "Animation" (no third sub menu)


Ella, teapot and diagrajamal1 your last ones very

Hi PixLab.

When you look at the code without trying it, "Animators" seem to create an extra submenu.
But it's not like that.
You've noticed that the "Animation" menu is divided into two sections;
- top: for various creative animations,
- lower: for generic tools?
Adding "Animators" just tells Gimpwi to place the plugin over the dash (and it doesn't show).
And one more thing: three dots [...] at the end of the plugin name indicate that the GUI has been displayed (no dots - the plugin will run automatically as there are no options to choose from)

A little test using an old gif I made.



I'm using the stand alone gegl (sudo apt install gegl)
My script is cave man style and it's easy to understand what it does. I'm interested in how Marero's works. The trick with applying to animation is getting the same number of frames in the effect and in the animation.

Thank you so much MareroQ, I just learn a lot from your very well explained "Animators"

Thus I have a question ,
Do you know if it's the same wording for others menus? In Light and Shadow (Filters > Light & Shadow) there are 2 dashes/3 blocks, how can you define the top/the one in between/ and the bottom?

Again a big-big

@ PixLab

I gave You a 'fish', not a 'fishing rod'...
This can be easily deduced from the "pluginrc" file or from the xml files in ...\share\gimp\2.0\menus\ (a bit more complicated).
You can also look at a specific plugin or script.

Sorry about that, some time I can be a bit too curious.



Thanks a lot, I'll take a look at it, I'll find a way

In all cases, than you so much MareroQ, I very much appreciated your help

MareroQ, Thank you very much for your explanations

I've made the menu changes you suggested.

Thank you. It looks like mainly the file image-menu.xml to see what the placeholders are. Are the conventions like that and the name three dots ... written down somewhere? If there is any documentation it would help to find out about other similar conventions I don't yet know

As you suggested I've switched to have the user specify the number of frames instead of the step.

The hue now starts at 0 instead of -180 to aid doing transitions like Tas_mania's.

Also added a reverse option:

Example output saved as as gif:

Reverse:


PixLab, I'm glad you're curious as you asked the questions I also wanted to know the answers to

That looks great
