Continuous Droste Effect

The Continuous Droste effect is a great effect and I am enjoying playing with it.
It’s located in Deformations>Continuous Droste. The Continuous Droste is unable to create the standard circular Droste. In Mathmap it works normally, but in G’MIC it comes up rectangular and is unable to create the standard circular Droste. When you select ‘No Transparency’ in Mathmap, you get the standard Circular Droste. When selecting ‘No Transparency’ in Continuous Droste you get a cropped rectangular Droste instead of the circular Droste. I did post screenshots on GimpChat showing the issue in more detail. I’m new here and don’t know if I am allowed to post a link to the post with the screenshots on GimpChat.

Initially I posted the issue on Flickr’s G’MIC page and then on GimpChat. I was told to post it here because this is where it would be seen and looked into.

Thanks in advance!

Absolutely you may post a link to the flickr/gimpchat threads. It’d be helpful if you posted it here too, that way if other people find this post, they don’t have to crawl all over the web. @David_Tschumperle is here often answering questions, but it is the weekend. :wink:

@PhotoMaster, I’ve contacted @Souphead about this issue (he is the one who converted this Mathmap script to G’MIC). I think we need to wait for his answer :slight_smile:

Here is a link to the GimpChat page that I posted the screenshots on.

In the mean time I will see if I can figure anything with the G’MIC coding. I’ve never written for G’MIC, but I did code for MathMap. I need to figure how to look at the code for G’MIC filters.

Thank you all!

Just for info, you will find the code for the Droste filter in this file : https://raw.githubusercontent.com/dtschump/gmic-community/master/martin_souphead.gmic

this one is a bunch of fun!

Sorry it took so long - had ‘life things’ taking my times. It should be good now. G’MIC should be built within 2 hours of this post with the fix. Refresh your filters and it should be there!

Kind of subtle but obvious when you think about it. Surprised the bug was undetected for so long actually. Any further weird stuff, let me know.

Souphead.

I tried hitting the update filters, but the update isn’t showing. I’ll try again in a few hours.
I also tried G’MIC Online and it’s not updating there either.

I’ve uploaded the updated filters on the G’MIC server.
It doesn’t seem to change anyway for me in the Continuous Droste filter, not sure if I’m doing something wrong.

No it was me. There are two parts of the code that look very similar and I put it in the wrong one. I recommitted the code.

Ah yes, it works now :slight_smile:
Thanks !

Thank You! It works now, but I have to re-update it each time. It reverts back to the original script each time I use it.

Ah really ? That is not normal.
Could you try to re-install latest version of the plug-in from the G’MIC web site to see if that still happens ?
Thanks for your help.

I had the same problem with the update not staying (the machine I had was 1.7.2_PRE). I updated to 1.7.4_PRE and the update stays. Not saying there is a problem with 1.7.3 - I simply didn’t try that one. This is on Windows.

I was having the problem with 1.7.3 and the problem went away with 1.7.4_PRE. Thank you Souphead and David_Tschumperle!

OK, good news then. Everything seems to run fine now :slight_smile:
(until the next bug is discovered!)

hello.I am a bit lost.where can I find 1.7.4_PRE ? I am part on Ubuntu 14.04 and 16.04.should I compile from github ?

Yes, that’s usually fine to compile the latest sources from github.
You will find 1.7.4_pre from the repo : GitHub - dtschump/gmic: G'MIC is a full-featured open-source framework for image processing, providing several different user interfaces to convert/manipulate/filter/visualize generic image datasets, ranging from 1d scalar signals to 3d+t sequences of multi-spectral volumetric images, including 2d color images. http://gmic.eu
Or you can try the latest sources from here : http://gmic.eu/download.shtml

trying to compile . it complains about gtk

I have gtk-2.0 installed

locate gtk.h

do I need gtk3 ?

I was missing libgimp2.0-dev.sorry
