I'll have to go back through them again and look. most of them do though. Oh if you want to look back at the start of this thread. It would be the ones I didn't include except Serendipitous Circle which I didn't see.
I tried Serendipitous Circle with colour.

Sallyanne - some need an alpha channel to work. Overblur does.
Thanks Tas
I'm sure we never had to add alpha channels if using gimp/GMIC filters etc. once.
But thanks, I'll see which ones didn't work for me then I'll check if that was the problem.

Sorry Rep other filters did work for me before but I only posted the ones that I liked the most.
These ones dont work for me - Or I cannot figure out how to make them work properly
Axis Streak (Tried with & without Alpha channel)
Edge fade(Leaves image blank or no change)
Graduated Filter needs alpha channel
Graphical Tiling Glitch
Grouped Pixel Axis-Based Shift
Grouped Pixels Shift by Rectangular Polar transformation
Non-Convolution Edge Extrusion
Object Size Filtering
Panel Image
Persective Streak
Picture Mosaic [Apparently I dont have the pictures?]
Reverse Engineer Blank Colour Curve
Reverse Engineer blank Gradient Map ( I dont have any gradient.png's)
RGB - Gray Linear Interpolation
Z time

Most of the filters of my own are designed around image editors in which layers all has an alpha channel by default. Paint.NET, and Krita are the main focus of those filters. So, it's inevitable that at least one or two would go amiss. I will update Overblur as I thought it wasn't interesting to use, but I was wrong on that.

Thank you for testing these filters, anyways.


Axis Streak is supposed to be used with layer(s) that contains alpha that has a shape in it. Variable alpha is supported here.


See above.


Definitely amiss in this case, I will update this after 3.1 is released. I can't work on filters now as 3.1 seem broke for me.


You need to have multiple layers for this.
An example of what this filter is for - https://i.imgur.com/bhIu8zp.png

Hence, the name.


Grouped Pixel Axis-Based Shift is supposed to be used with layer(s) that contains alpha that has a shape in it.


Same thing as above. Need layer(s) that contains an alpha that has a shape in it.


I will have a look at what's going on here, it's suppose to work, but I can only look after the release of 3.1.


For this one, you need to have multiple shapes alpha. It is about filtering objects.


All this does is move the image around. You don't need it as there are other plugins methinks. I only coded this for making things easier on Krita.


You need to have a image with alpha containing shape here.


All you need is a folder with pictures in .png format, and then change the folder target to that folder.


You need to have two layers for this. One layer with color curve adjustment, and the original image. I think I will add a .png exporter for this for people to export the color curve gradient.

So, when you get the color curve gradient, you put that to a new image. Then create a black and white gradient, then attempt to match the color curve gradient, finally put that into preset.


You don't need gradient. You need to have one image that is black and white (which contains multiple channels in it), and a gradient mapped image. This will give you a gradient.png from it. I will also add a .png export for this.


The effect is pretty subtle. Try putting all factors to 0. If it doesn't work, then there's a bug indeed, and I'll have to address it after 3.1 release.


For this one, you need to have 3 layers at the minimum. The top layer must be a black and white gradient. The gradient itself can be non-standard, and I would recommend non-standard gradient as this allows you to have interesting output.

Thank you the comprehensive answer.

By the way, I was able to fix Graduated Filter now that I managed to get 3.1 working. Though I don't have G'MIC 3.1 GUI yet though.

For Non-Convolution Edge Extraction, you can change color space to RYB so that you can get a idea of what it is. It works when you do that.

This is the vs I have

At the moment I cannot update the GMIC filters

So I still cannot do a couple of them. Never mind, I am not hanging out for them to work. Thank you for the ones that do.
Edit: Cannot see that version can be got any more so I went back to 3.0.2 and it looks like some filters are working. Also update worked.
Edit again, I got Axis Streak, Edge fade,Reverse Engineer Colour Curve and Z Time (finally) to work

I have just come across that error message, I assume some change David has made in the update compression format.



Top version is from 'older code' compiled on the 16 th. Bottom is from latest code and compiled 20 th. (yesterday)

You could try an update (of the whole plugin) but as you say, only one filter out of 570, maybe wait for gmic 3.1 to become stable. Updates not as essential these days as the 'community' definitions are incorporated into the plugin.

Where can I get 3.1 from Rich?

Gmic 3.1 is still pre-release and the list is here: https://gmic.eu/files/prerelease/
The Windows installer download is https://gmic.eu/files/prerelease/gmic_g ... _win64.exe - that is dated 2022-04-19 - the latest code.
Lots of changes to the code recently, I think most of the bugs fixed, (but not all )

Thanks.

I have updated Hitomezashi. I will try to update Serendiptous Circle. I did made a quick update, but not ready to update it for ease of use.

That is an interesting one - Hitomezashi I just tried Newton fractal (Madjik style) again and it has come out brilliantly, well the preview has. 12+ minutes later I am still waiting for it to finish. I have just noticed that it can take a while (computationally intensive) and my computer is going slow of late any how.
It did it!

Newton Fractal (MadJik style)

I would highly recommend you to use the other Newton Fractal as it is so much faster and easier to use. I'm not exactly sure how to get the same rainbow output in there though.

Thanks Reptorian. I think I have used it before. I can wait if it takes a while. Besides I like those colours. Thanks for creating it.

Hi Reptorian,
I'm not having success with Vibrato and Overblur using GMIC cli version 3.1.1 pre-release. They used to work with cli 2.x.
I either get black images or a single pop-up image that I can't save.
The Vibrato code line is really long.

Probably not many (if any) people do cli processing. I often use 360 frames to get a never-ending loop.

Here is an example of one of the loops.
