[Bug 179802] New: After raw import image not shown in editor

http://bugs.kde.org/show_bug.cgi?id=179802

           Summary: After raw import image not shown in editor
           Product: digikam
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: RAW files management
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           0.10.0-rc1 (rev.: 906212) (using 4.1.85 (KDE 4.1.85 (KDE 4.2
Beta2)), Kubuntu packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.27-7-generic

With color management enabled, and the option "ask when opening an image in the
image editor" selected, the raw converter shows the following bug: After the
conversion, clicking on "import" should open the decoded image in the image
editor. But the image editor shows only the blank background in this case.
However, for example a "zoom 100%" displays the image properly.

With color management switched off, or with enabled color management but
selected "apply when opening an image in the image editor" selected, I did not
see this bug.

Gilles you understand more about color profiles than me.
I see two bugs in this area:
If an image has an embedded profile, the result from "Convert" is the same as
from "Assign". The preview for "Convert" however, is different. See first
following screenshot.

If an image has no embedded profile, the conversion preview does not match the
conversion result. See the following screenshot 2 and 3. Here, the result from
"Convert" is different from "Assign", but the preview gives a third version.

In all cases I cannot say what should be the correct result, but obviously,
something is wrong here.

Embedded profile dialog

Image with embedded profile. The preview for "Convert" in the dialog is darker,
both "Convert" or "Assign" will not change the output in the main view.

Import dialog without embedded profile

This image has no embedded profile. See how the "Convert" thumbnail is very
bright.

No embedded profile conversion result

Now this is the result from "Convert". The preview was brighter than the
original, now the result is darker (and does not match the preview)

This might be the same problem as the one described in 182272. See the test
images linked there in comment #1.

With the recent color management rewrite this bug is solved for me. When I
select RAW output colors in the import tool and "Ask user for profile" in the
settings for uncalibrated data, I click on import, get the dialog to select and
input profile with a working preview and the uncorrected image already in the
background.
