Description Gilles Gravier 2017-09-04 12:07:26 UTC
Description:
I have a specific file which was created in PPTX. When I open it in PPTX the image inside it is properly proportioned and displayed black and white. When I open it in LO5.4.1.2 (on Windows and on Ubuntu) the image is displayed stretched vertically, and in color. Seems that the graphics formatting for the object is ignored.

Steps to Reproduce:
I will upload files after
1.Open the pptx file on PPTX... looks fine.
2.I am providing 2 PDF files which shows how PPTX and LO541 render the document in PDF... It is similar to displayed content.
3.

Actual Results:  
The file is incorrectly displayed on LO (image in color, incorrect proportions).

Expected Results:
Image should be black and white and with correct proportions.


Reproducible: Always

User Profile Reset: No. But it happens on Windows and on Linux with 2 different profiles.

Additional Info:
Uploading 3 sample files once bug is filed.

This is the test case file. It's in PowerPoint. Opening it yields incorrect display.

The attached PPTX file opens incorrectly in LibreOffice. The image in the slide is displayed in color and streched vertically. It should be displayed properly proportioned and in black and white.

Sample on how the file should be displayed

This is a PDF generated from PowerPoint. It shows how the file should be correctly displayed.
