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.
