Re: [Gimp-user] Histogramm -- values
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
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. -- SeBaer (via www.gimpusers.com/forums) ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list
[Gimp-user] problem with mouse and bamboo pad
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, -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.orgopenSUSE Community Memberfacebook/ptilopteri http://wahoo.no-ip.orgPhoto Album: http://wahoo.no-ip.org/gallery2 Registered Linux User #207535@ http://linuxcounter.net ___ gimp-user-list mailing list List address:gimp-user-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list

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

[Gimp-user] can't add new fonts
Hello, I have Gimp 2.8 installed on my laptop ( using Windows 7 Home Premium) and after successfully installing new fonts to on my laptop, I can't see them in gimp. I tried to copy them to fonts folder in gimp but still nothing. I saw there were several fonts folder and I think I have tryed them all with no success. Someone could help. Thank you.
