Bug confirmed here, I’m investigating…
Apparently, this is fixed with this patch : https://github.com/dtschump/CImg/commit/6fbf12e4d838c8140852790c1e8ab89650c93c64
It was a bug in the CImg Library function
I’ll post new pre-release packages of G’MIC including this fix tomorrow
I’ll watch for it and report back when I get time
I’ve been finally able to post new binaries for the 2.2.2_prerelease version of G’MIC, including the bug fix for the guided filter.
Available for testing here : http://gmic.eu/files/prerelease/
Feedback appreciated !
Thank you very much for this nice filter. Very, very good with old newspaper halftone images. I can achieve nice results in minutes, instead of half an hour.
edit: The preview options are incredibly helpful, especially the FFT difference preview.
