Description animtim 2014-06-12 10:07:03 UTC

When using the color picker on a transparent area (using current layer mode, or in normal mode but with transparent background..), it doesn't pick alpha value anymore in the selected color as it did before, which could be convenient in some cases as it's the only direct way one have to know the alpha value of an area.

More, if you look at the Tool-options docker , you can see it always show alpha 255, making this line useless.

So please at least make the tool docker report the correct alpha value, and possibly make an option for the color picker to select alpha value as it did before. 

Reproducible: Always

Actually, I had a patch that gave both options, and lost that :-(. It's definitely something to restore.

[FEATURE] Fixed painting and color picking on global selections

This patch fixes three problems:

1) Painting on a global selection now is not recursively limited to
   the selected area of the selection itself. If current node and active
   selection mask are the same entity, KisResourcesSnapshot will report
   no selection active.

2) Color Picker can now pick from selection masks. Yes, it converts the
   color into compositionSourceColorSpace() to make it paintable.

3) The Color Picker's option widget now shows alpha value correctly,
   although the resource server gets opaque color.
