& Modifications_gmic-qt-3.4.3-Win64-QT6_V4.7z
EDIT 20241109: New version V2 from November 9, 2024 with QT6 (64 bits)

Remarks :

• Changes made to the Gimp plugin are not validated by the GMIC-QT maintainer https://github.com/GreycLab/gmic-qt
• Sources and modifications are in \gmic-3.4.3_Gimp-3.0.0-RC1-TEST-Win64_V2\sources

Problems and corrections on this V2 test version with GIMP:

• Correction made for operation by validating several layers.
• Guided Light Rays works on version V2
• The 'What's new' filter gives an error (G'MIC shutdown), as in previous versions compiled with QT6.

The G'MIC 3.3.4 archive contains compilations for Windows:

• GMIC-QT6 Win 64
• GMIC-QT6-GIMP-3.0.0-rc1 Win 64

This new version gmic-3.4.3_Gimp-3.0.0-RC1-TEST-Win64_V2.7z is available for download.

The installation is in the readme.txt file.

Do not mix executables and DLLs.

Tested with GIMP-3.0.0-rc1 CLANG (gimp.org) and MINGW64 GCC (samj).

Antivirus tested.

This version, compiled with an up-to-date MSYS2 environment, has a problem with the Box Fitting and Pack Ellipses filters which display black images in G'MIC QT and G'MIC GIMP QT.
This problem does not exist with these same filters used on G'MIC CLI.
Compiling in an older MSYS2 environment would remove this problem.
