Description BVZ 2018-10-22 00:40:36 UTC 
Description:
I often work with documents that include a 'watermark' image, such that the image itself is formatted to be transparent and in the background of the page. I can edit, and save, this kind of image formatting with no problems in *.odt documents, but the changes never save in *.docx documents.

Steps to Reproduce:
1. Take *.docx document with image transparency formatted into a part of the document 
2. Open using LibreOffice
3. 

Actual Results:
The image with some percentage of transparency appeared as if it had no transparency.

Expected Results:
The image formatting should stay the same, whether the document is being worked on in Microsoft Office or LibreOffice.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Hello BVZ,
Could you please attach the original .ODT file? Otherwise, we can't investigate this issue.
I have set the bug's status to 'NEEDINFO'. Please change it back to 'NEW' once the requested document is provided.

Hi Xisco,

Thanks for looking into this. The problem actually does not concern image transparency when working in *.odt files, this feature works as intended.

The problem is when one tries to save image transparency in *.docx files, closes said file with image transparency setting, then reopens that same file. The 'saved' image transparency does not appear as saved and the image only appears with its initial opacity.

Hello BVZ,
Yes, i know, that's why I'm asking for the original .ODT to investigate the conversion from .ODT to .DOCX

Hi Xisco, I see, understood and uploaded. 

Also FYI, I did some other photo editing saved to .docx recently and none of it saved when I reopened the document. These issues didn't involve transparency, but possibly related since they are about saving in .docx.
