Does the problem recur after a Gimp reboot?
Has the secondary console window disappear?

Rebooted gimp and Fan Illusion is missing:

It is possible that something went wrong with pasting the code.
Try from the attachment.
This version in menu Gimp: Filters -> Animation -> BA Fan Illusion...

Attention:
You must use an image:
1. With alpha
2. And transparency (even if the transparency is a 1 pixel eraser in a corner).

A plug-in with this patch can be downloaded in the post #54

I'm rebooting gimp again. Hopefully the plugin is in Filters->Animation->BA Fan Illusion. Fingers crossed!

I rebooted gimp and your new version the one you attached is there.

Hi MareroQ
Sorry for delay in posting. You post #37
Had some other things to deal with.
Here is my example.

What is required to make this plugin work? I ask because I get errors.

The black console is gone?
Check if the image has an alpha channel.

What do you mean by the black console? No, there is no alpha channel. Should images with out alpha channel have alpha channel added to it in order for the plugin to work? I ran the plugin with alpha channel and I still received the errors.

"Black console" - You showed in post #38.

You must add an alpha channel before running the plugin. The best effects are the "object" on a transparent background.

Yes, the black console is gone and I added the alpha channel to the image before I ran the plugin but I still get the same errors.

Probably the same condition as for SpiderPaint is required:
You must use an image with alpha and transparency. Even if the
transparency is a 1 pixel eraser in a corner.

So, basically the only images that can be used with this plugin are .png images. Those are the only ones that have transparency. Jpg images fail when running the script even if you add an alpha channel.

@MareroQ
I applied my "quick and dirty" solution also to Fan Illusion (similar to the one of Spider Paint).
Here the modified version, suffixed M.
It should work.

Thanks Diego. Oh, with polar coordinates, does that mean that any numbers can be inputted?

Here's my try at your modified version:

@MareroQ,

I did get your version to work by using only a .png transparent image:

@Mackenzieh



That's not true. I am convinced that you did not fulfill the second condition - erase any pixel with the eraser.

@Diego.
Thanks. This will save some time for clarification.

Another matter.
Do You remember the BA_Plasmatic.py plugin?

I adapted it to 2.10 but should this be the result?

Ran exaggeration and on the first try it's fine but on the second try with the same photo I get errors:



The error is the same whether it is yes or no

You don't have the latest version - there was a bug fix.

Which post is the latest version?
