Description animtim 2011-12-11 12:21:06 UTC 
Version:           svn trunk (using KDE 4.5.5) 
OS:                Linux

In 16 and 32 bits float files, eraser mode doesn't work.
Same thing for almost all blending modes : only Normal, Copy and Darken can be selected (but Darken doesn't look to work different from normal ; and when using deform tool in Copy mode on transparent layers, it produces strange artefacts, not sure if it comes from copy mode or deform brush).

Reproducible: Didn't try
Comment 1 animtim 2011-12-11 12:23:14 UTC 
Of course always reproducible (sorry I forgot to precise it in description)
Comment 2 Cyrille Berger 2011-12-11 16:34:06 UTC 
Eraser -> bug
Everything else -> wish
Comment 3 Halla Rempt 2011-12-24 10:38:26 UTC 
We also shouldn't show non-working composite ops. This is likely related to the categorized composite op view by plassy, though.
Comment 4 Halla Rempt 2012-02-26 11:47:47 UTC 
The erase composite op is now implemented; the non-existent composite ops are grayed out and flagged with an icon. The ctlcs darken compositeop actually is alpha darken, and is now correctly tagged.

The rest needs to be implemented still :-)
Comment 5 Halla Rempt 2012-08-28 14:24:19 UTC 
This is fixed now with the replacement of ctl-cs based hdr colorspaces with lcms2.4-based hdr colorspaces.
