Re: [Gimp-user] Histogramm -- values

2013-12-02 Thread Wolfgang Hugemann
OK, colour spaces are very confsing, but a very basic point is that the 
human spectral sensitivity has a pronounced peak in the green region, 
see http://en.wikipedia.org/wiki/Luminosity_function.


This is why any function deriving the perceived brightness or luminance 
from RGB, such as Rec709Luminance (0.212656 * R + 0.715158 * G + 
0.072186 * B) weights the green far more than red and blue. This just 
reflects the spectral sensitivity of the human eye.


The perceived brightness of purely red image at, say, 100 bit will be 
far less than that of a purely green image at 100 bit. Correspondingly, 
the latter should result in a leighter equivalent grey than the former.


Gimp proceeds this way when converting a colour image to grey, as I have 
just tested:


100 R -- 21 G
100 G -- 72 G
100 B --  7 G

This is very close to Rec709Luminance.

I just suggest that it should offer such a weighting in the histogramm 
for a colour image, i.e. the equivalent grey value at Gimp itself would 
calculate it.

[Gimp-user] libglib-2.0-0.dll error after upgrading to 2.8.8

2013-12-02 Thread SeBaer

Someone should recompile the third-party ufraw plug-in with a recent
glib.
As I have the same problem, I wonder why Gimp 2.8.8 does call ufraw anyway for
opening a .jpg? Gimp 2.8.6 opened any image file apart from raw data without
ufraw even beeing on my harddisk. And as far as I get, ufraw development seems
to have ceased.

[Gimp-user] problem with mouse and bamboo pad

2013-12-02 Thread Patrick Shanahan

openSUSE Tumbleweed
gimp-2.8.8-80.1.x86_64

Just about had heart failure.

Cannot select or draw or crop using my mouse.  Then realized that I had my
bamboo pad attached and found that it worked.

Will not the pad and mouse work together? or have I stumbled blindly onto
a possible bug?

tks,

Someone I know just had the same thing. Well I did not think about
whether that would be the Wacom (intuos 5 here)'s fault because her
tablet is always plugged in. But same, she could not select/draw with
her mouse. She could with the laptop's pad and the tablet.
I'll see if we can reproduce later.

No that's supposed to work (as 2 separate devices). So that's
definitely a bug. If I can reproduce it, I'll try and fix this.

fwiw this my experience (Intuos 5 touch M) as well.
I figured I'd done something wrong in the settings.
