Hello.
I'd appreciate votes and watches on this feature request=2C to bring this f=
eature to the Qt low-level pixel processing code:
https://bugreports.qt.io/browse/QTBUG-45209

Krita=2C Photoshop and other professional packages offer some form of gamma=
-corrected blending=2C it makes all sense to have this implemented in the Q=
t painting system as well so developers don't have to look for external sol=
utions. I wonder what's the way that Krita implemented this.
An alternative is to not use the painting functionality in Qt at all=2C and=
 resort to OpenGL and Direct3D to perform these corrections.

PS: The "Developers" page of the Krita website could add this to the "Resou=
rces" section: http://www.ics.com/designpatterns/book/index.html
It's a full book in HTML format. I've learned a lot from it.

Regards. 		 	   		  =
