</div>Letting KDE or Gnome Desktop color management handle all ICC profile<br>
conversions from the image window to the display screen would require<br>
a rewrite of all the color-managed applications to remove or at least<br>
make optional the relevant color-conversion code (to avoid<br>
double-conversions), and a rewrite of the Gnome AND the KDE Desktop<br>
code to add ICC profile conversion code, plus the ability to detect<br>
which color-managed application window wants which ICC profile.<br>
<br>
It seems to me that having the Desktop do all ICC profile conversions<br>
from the image window to the display screen would limit the user's and<br>
also the editing application's creative choices: What if the user<br>
wanted to use relative colorimetric intent for one open application,<br>
perceptual for another? Or use a LUT monitor profile for one<br>
application and a matrix monitor profile for another? Or use<br>
highest-quality ICC profile conversion for one open application and a<br>
lower-quality profile conversion for another?<br>
<br>
What if you are trying to softproof to the screen in one open<br>
application, while in another you are merely looking at images? What<br>
if one application wants to use cairo and another doesn't? I've looked<br>
at the ICC profile conversion code in digiKam (older version), Krita,<br>
Cinepaint, and Gimp. All of these color-managed applications use LCMS<br>
(1 or 2, depending). But each of them uses LCMS ***very***<br>
differently, even for such a "simple" thing as sending information to<br>
the display screen.<br></blockquote><div><br></div><div>Of course, I agree that many aspects of color management should be at the application level for greatest control by the user. I just wish it isn't (and don't know why it seems to be) so slow using it in digiKam. (I still need to try making a new profile w/ my colorimeter, maybe trying new settings.) Not sure if there is indeed a mis-connect going on somewhere, or maybe digiKam's CM can be changed, if not already, to leverage multiple CPU cores and/or GPU.</div>
<div><br></div><div>In any case, I think I am seeing correct colors without it for now, since my monitor profile (created with RBG option) that's set in system is correcting my monitor, and my images are (s)RGB. </div>

</div>That is interesting. As you say, it appears that digiKam (a KDE/qt<br>
app) isn't aware that colord assigned a system monitor profile. Do you<br>
have Gimp (a Gnome/gtk app) on your computer? Is Gimp aware that you<br>
have a system monitor profile? </blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
