Created attachment 152334 [details] Screenshot of the bug. SUMMARY Invisible watermarks added with Fourier Watermark cannot be viewed in Fourier Analysis. In the Fourier Watermark description, it is written to use Fourier Analysis to view the watermark, but in fact, the watermark can only be seen in the Fourier Transform. STEPS TO REPRODUCE 1. Open the picture you want to add invisible watermark with krita. 2. Use G'MIC filter-->Fourier Watermark to add invisible watermark. 3. Export as png. 4. Open the png you just exported with krita. 5. Use the G'MIC filter --> Fourier Analysis to view the added invisible watermark. OBSERVED RESULT Watermarks cannot be viewed in Fourier Analysis. The watermark can only be viewed in the Fourier Transform. EXPECTED RESULT View the watermark in Fourier Analysis as described by Fourier Watermark.

Sorry, we cannot really do anything about this in Krita, since g'mic is a third-party component. They track their own bugs here: https://github.com/GreycLab/gmic/issues

No need for apologies! It's not something you could know beforehand!

This component tracks bugs in the Krita-G'MIC communication, e.g. if the images are properly sent and received between the two apps, if the app follows our users' preferences in Krita (since we run it in a plugin-ified mode), etc. Features specific to G'MIC, including but not limited to filters and functionality in general, need to be reported to: - filters: https://github.com/GreycLab/gmic/issues - Qt GUI issues: https://github.com/c-koi/gmic-qt/issues
