Color space info lost

[darrask]

I've encountered a problem which appears to reveal the current version of XnView does not preserve color space information when converting or exporting photos anymore.

I have adobeRGB TIFFs which, converted/exported to TIFFs (using Ctrl+U or Ctrl+Alt+S) or any other format, apparently lose their color space information. The resulting converted pics look dull. When ICC color management is disabled, they look the same as the TIFFs, which now display as sRGBs.
This is a new problem as I could compare the pics I generated just now with those I converted a few weeks ago with the previous versions. The older ones display correctly, identical in color to the original TIFF.

We could confirm on another computer with various pics that the previous version 1.93.6 did not have this problem.

Tested on adobeRGB TIFFs generated with Raw Therapee 2.4 ml of Olypmus E-420 an Nikon D40 as well as other pics from Canon 400D on 2 Windows computers.

Right, this has been changed, some users have problems if convert keep ICC
So now, i must add a new option for convert too

For information:
1-)To keep embedded ICC profile inside the image after any XnView operations & save (FYI:any older XnView versions have never done that before):
As XnView has an option for : "Edit\metadata\clean" ICC Profile to erase the embedded ICC info, XnView should also has an option into: "Options\read/write\write\jpeg" "Keep embedded ICC info" inside the .jpg.

2-)To apply the ICC profile (as filter) to an image without an embedded ICC profile (like the old version mentioned above v1.93.6 )
XnView must also has a kind of filter for convert (batch processing "Ctrl+U") to apply the colors correction without keeping embedded ICC profile into the image.

So these two solutions are needed in a future XnView version.

OK, I see that in the older as well as in the current version, the color space info is lost in the generated/converted files: this is what you see in the properties panel, color space info absent upon conversion no matter what's the version.

However, adobeRGB Tiffs converted to jpegs using XV 1.93.6 (ICC management checkbox enabled) display the correct color. To me it suggests that the old version left the color space tag intact and that XV (new and old) is able to recognize it, even though it does not show in the properties panel.

Am I wrong? Maybe I did not get something, The discussion here got quite messy.

Maybe (even if in the properties panel, color space info is missing) !

I said that the old version maybe left the color space tag intact, and indeed my old pics converted with 1.93.6 have an embedded adobeRGB tag like the original files, this is recognized by Adobe Photoshop.
