Description johan 2018-03-10 13:45:17 UTC
Some EMF (Windows Enhanced Metafile) files are not displayed correctly when inserted into Writer or opened in Draw. Examples and a screenshot of Microsoft Word for comparison are attached below.

The following problems occur:

1) Lots of empty extra space is included on the right and bottom sides. 

2) The top part of the image is hidden when inserted into Writer. It will become visible if you use the crop tool and pull the top left crop handle outwards.

3) The curves extend outside the plot area even though they should not.

4) Additionally, the aspect ratio of the portrait example is wrong and the text elements are completely messed up.

Please note that Inkscape does not show the examples 100% correctly. You may need Windows software to view them correctly.

Steps to Reproduce:
1. Download and unpack the example files below
2. Insert the example EMF files into Writer or open them in Draw
3. Compare with the screenshot which shows a reference rendering in MS Word

Actual Results:  
The problems explained above occur.

Expected Results:
The images should look approximately the same as shown in the screenshot.

Reproducible: Always

User Profile Reset: No

Additional Info:
Tested with two Libreoffice versions on Windows and Linux.

There can be only one issue per report.

Please test with 6.0.x to be sure the problems are still current.

Then go through these to find existing reports: https://bugs.documentfoundation.org/showdependencytree.cgi?id=103859&hide_resolved=1

Finally, open a separate report for each remaining issue.

All problems still occur. I'll create separate reports soon unless someone wants to comment here.

List of know EMF/WMF issues: bug 103859

The description is pretty detailed. However, the (main) problem is pretty obvious.. this report will do.. Didn't check for similar reports
Comment 5 Buovjaga 2018-03-18 11:15:47 UTC
1) is seen when you select the object and notice the object borders. I wonder, if the file has clipping info and it would be the same root cause as bug 48916?

I cannot see the problem 2).

4) looks like bug 103903

So in my view there is no single "main problem".

Problems 1) and 3) are visible in this.

Still curious about 2). Could johan produce a screenshot of it?

Screenshot of nr. 2

Screenshot showing 2) attached. It occurs when the image is inserted into Writer.
Comment 9 Buovjaga 2018-03-24 16:27:59 UTC
Ok, let's make this report be about problem 1).

As problem 4) is likely bug 103903, please create new reports for problems 2) and 3).

Mention the new reports here, when you have created them and we will confirm them.
Comment 10 johan 2018-03-25 15:22:55 UTC
2) reported as bug 116622

3) reported as bug 116623

Additional notes that may be useful:

3) occurs in Inkscape as well (already reported)

4) occurs in Inkscape as well (already reported)

2) occurs in Inkscape - the image is placed partially outside the page/canvas area (not yet reported)

1) may occur in Inkscape, a matter of definition. The canvas/page area is much larger than the image itself when the image is opened. (not yet reported)
