I think we basically agree about this in fact, but you are not quite 
understanding what I was saying. To answer your points above, I agree 
that the KDE software should encourage the use of sRGB, at least for 
when images are targeted for display on the web, to ensure the greatest 
amount of interoperability with current software, including non-KDE 
software. But we cannot prevent people from making other choices. There 
are many valid reasons for wanting to use a different colour space, 
which is after all why the other colour spaces exist in the first place. 
So it would be very good to get an option in the various web upload 
plugins in digikam to convert the images to sRGB as part of the upload, 
possibly even make it the default action. But if the user chooses not to 
do that then any pre-existing embedded profile should be preserved 
through the resize process.

What I was saying was not about new images created or edited by KDE 
software but that in order for the KDE software to be able to best cope 
with images that are not in sRGB but do have an embedded ICC profile 
then that should result in an image that can be displayed properly 
directly on the user's computer. Currently Gwenview seems to be ignoring 
the embedded profile. This is just a bug that should be fixed IMO. This 
has nothing to do with non-KDE software nor anything to do with display 
on the web. I have the file locally and it is not rendered correctly by 
the KDE software I have on this machine.
