Im having issues with the 1.6.5.0 version plugin of gmic.

some fast fast facts:

gmic version 1.6.5.0 (64bit)
gimp version 2.8.10 win64 + linux mint 32 and 64 bit (ubuntubased)
last known working gmic version 1.6.0.4 (same platforms)

not working gmic filter : smooth wavelets (located under repair category)

computer platforms : tested on several hardware diffrent computers with same results, as a reference :
i5, 4 gig ram nvidia graphics, i5 4 intel hd4200 graphics, and a intel xeon workstation 8 gig ram and amd graphics.


The bug is that if u use the smooth wavelets filter (under the repair menu) u get a broken, black or just garbled up image
instead of the noise reduction. The type of "error" u get is diffrent depending on what channels u set the filter to work on.
The bug is shown in the preview image and on the processed image.
Tried changing the other setting for the filter with same results, tried adjusting the parallel processing to my cpu exact specs.
this only results in additional variations of garbled image.
The other filters in the repair category works as they should.
The last known working version of gmic was the 1.6.0.4 version.
the issue is the same on either a windows 7 64 system or a linux 32 and 64 bit ubuntu based system.
If u revert back to the older version it works again som it seems its somthing with the filter itself in the new version.
Could only try the revert to old thing on windows since i dont have the old linux files and cant see them on ur /gmic webpage so cant use that workaround on linux.

Anyone with ideas?

attached images of nonworking filter and working filter, same settings and same "workimage"

the error occurs only using one of the first 11 options for "channels", starting from YCbCr it works using one of the remaining options
gimp 2.8.14 + gmic 1.6.5.0

edit: errors on options related to luminance/lightness, OK for the other options related to the chrominance (also in the first part of the options it works for a single colour, RGB red for instance)

This is correct, thanks for the reporting.
I've done a fix, please press the 'Update filters' button, the filer should work again.

Thanks.

yes, retested, now in all cases(any selection on channels) it works!
thanks, David

Yes have tested it as well and on all platforms it works.
Thanks for the fast fix.
