Description Ravindra Vidhate 2014-04-15 09:25:58 UTC
Problem description: 
The .TIF image is written as .TIFF while exporting the document from LO in DOCX format.

Steps to reproduce:
1. Open the attached file in LO which has images [.TIF] format
2. Save the document as DOCX 
3. Open the saved document in MS-Office or extract the content of the saved docx file. In [Content_Types].xml , .tif extension is changed to .tiff.

Current behavior:
In [Content_Types].xml , .tif extension is changed to .tiff.

Expected behavior:
In [Content_Types].xml , .tif extension should be preserved as it is i.e .tif.

Verified On LO Build :libo-master~2014-04-14_08.54.29_LibreOfficeDev_4.3.0.0.alpha0_Win_x86.
Operating System :Windows.

In [Content_Types].xml , .tif extension is changed to .tiff after RT.

set status to NEW according to previous comment confirmation.

anyway, would you please explain what's the problem about having a .tiff extension rather than a .tif extension?

is this extension change responsible of any issue with the document?

TIFF file can be labele either with .tif or .tiff extension, just like JPEG that sometimes are shown with .jpg or jpeg extension
Comment 4 Ravindra Vidhate 2014-04-15 14:15:34 UTC
.TIF extension is used in MicroSoft Naming convention [3 char extension] standard 8.3.
The later on Microsoft adds the support for .TIFF.

The main issues is when you insert .TIF file into docx file in MS-OFfice and then saved[exported] in LO then .TIF file gets converted to .TIFF.

The document having .TIFF will not be showing images when open on XP and below.

We also need to do implementation of .TIFF similar to .TIF if required.

OK. thanks for info.

what about LibO 4.1.x or 4.2.x ? do they have the same issue as LibO 4.3 alpha?
Comment 6 Ravindra Vidhate 2014-04-16 05:36:03 UTC

I have not tested on the versions 4.1.x and 4.2.x but feel that this versions will also have the same problem.
Comment 7 tommy27 2014-04-16 06:23:15 UTC
just to make sure you know that, if you change status to ASSIGNED it means that you will work to provide a patch to fix the bug.

if it's not what you intended please revert status to NEW so another developer will take in charge of it.
Comment 8 Ravindra Vidhate 2014-04-16 06:43:19 UTC

I have already submitted the patch for it. I am just waiting it to be merged. 

Once it is merged, I will update the issue with correct resolution.

Comment 9 tommy27 2014-04-16 07:20:00 UTC
great!!! by the way you may test 4.1.x and 4.2.x downloading portable LibO versions from this page.

it would be interesting to know if bug affects just 4.3 alpha or even stable releases

Not reproducible anymore, tested using Windows 8.1 with LibreOffice Versie:
