Description Halla Rempt 2010-08-22 11:22:29 UTC 
We used to be able to convolve on a subset of the channels of a paint device. This no longer is possible, but it is important for some effects and techniques.

To test, re-enable the testMaskConvolutionOnRedChannel test in KisConvolutionPainterTest.

Should it go to 2.3? I can take it, i guess
Comment 2 Dmitry Kazakov 2010-11-14 11:55:36 UTC 
Well, the test is fixed how can i check this in the UI?
Comment 3 Cyrille Berger 2010-11-14 15:09:03 UTC 
right-click on a layer (in layer box), disable some channels, then filter.
Comment 4 Halla Rempt 2011-07-19 12:38:24 UTC 
Despite fixing a lot of channel issues, this seems to be still broken. The unittest works file; maybe the channelflags aren't set in the filter config?
Comment 5 Halla Rempt 2011-07-19 12:55:51 UTC 
Looks like it... Working on it now.

Pass the layer's channel bitset on to the filter

Todo: make the filter layers and masks respect the selected channels
properly
