Export to .tif introduces artifacts...

[Katamara]

XnTriq,

Regarding a 'bug...
May I ask which library, or if XnViewMP is suspect for the 'bug' ?

Also, may you please reply to the below existing unanswered questions ? ;
Unanswered Questions;
a) How Can I preserve the same exported exif and profile metadata Exporting in XnViewMP from .jpg to .tif ?
c) Should the results of tests I've done in this thread be different in Windows 7 Pro or later, vs. Linux ?

Here is the dialog you requested;


Observations;
Save .jpg to .tif with XnViewMP 0.90, Linux Mint 18.3 Cinnamon
1) Cannot save .jpg to .tif without pixel changes, regardless if original .jpg has profile, exif or not.
2) Cannot save icc and exif information from .jpg to .tif
3) Nconvert is not applicable for lossless save with the original profile to obtain identical pixels in the resulting .tif

I forgot that there is no beta for Linux, so you have to wait for the final release of v0.91

XnTriq,

You are welcome.

I appreciate having the ability to communicate problems and receive replies from the creation team
however, it's confusing why you are continuing to ignore questions (below) in your replies.
I understand that my settings are correct.

May you please answer the below questions so I can proceed forward ?

There is no “creation team”. Pierre (AFK ATM) is the only developer of all XnView-related software. I'm just an ordinary user who happens to volunteer as a moderator, which is why I can only speculate if the issue stems from XnView's code or a 3rd-party library.

May you please answer the below questions so I can proceed forward ?

This issue has been identified as a bug by Pierre. The bug is marked as fixed for version 1.91, but I don't know when the final release will be available. Links to the bug tracker and the related forum discussions have been provided in one of my previous posts:

  • Bugs in color management when saving (XnView Classic)
  • Default profile for picture: use profile from picture
  • 0.90 Linux: display ICC profile uncorrectly applied to output image
  • Use ICC profile - Add "use monitor profile" option

XnTriq, Pierre...

Thank you kindly for your input and assistance on this matter.
I'll wait for 0.91 for Linux.

Best regards.
