Description kgeorge1967 2010-11-15 21:38:23 UTC
When I create a slide with Power Point and open it with Impress the lines and 
arrows are changed. Specifically, straight lines and arrows drawn on angles to 
the horizontal or verticle are depicted in a staircase fashion with Impress. I 
can upload an example if that would be helpful. I'm using version 3.2.1, build

Please attach document for testing. Thanks.

I have partially replicated this bug.

Straight arrows in PowerPoint drawings bend when opened in Impress

In my testing, when Impress opened drawings containing angled lines drawn using the straight-arrow tool in PowerPoint, Impress drew those arrows with one or more right-angle bends between origin and destination, instead of directly connecting origin and destination with a straight line.  However, lines of the same angles drawn using the straight-line tool remained as originally depicted in PowerPoint.

You can quickly see this problem in the two jpeg images I've attached, which show side-by-side comparisons of screenshots of the slides which differed between PowerPoint and Impress displays.

To replicate this problem, use Impress to open the sample PowerPoint file I have attached to this bug.  The only difference between Slide 2 and Slide 3 is that the text objects in one are connected using the straight-arrow tool while in the other they are connected using the straight-line tool.  In PowerPoint, these slides look identical except for the arrow-tips.  Slide 4 and Slide 5 also form a pair that differs only in what type of line connects the objects.

I conducted my testing using OOo-dev 3.4.0 DEV300m100 (Build:9571) and the attached PowerPoint presentation (created with Microsoft Office PowerPoint 2007) on a Windows7 system.

This is a startling visual change between PowerPoint and Impress, one which could complicate collaborations with PowerPoint users.

As a further test, I created a drawing in Impress using straight arrows and saved the slide as a .ppt file.  I then opened that file in PowerPoint 2007, added a new straight-arrow between two previously unconnected objects, and saved the file in both .ppt and .pptx formats.  When Impress opened the revised .ppt file, there appeared to be no problems, but when Impress opened the .pptx version of the file, the new arrow added in PowerPoint had acquired right-angle bends along its path rather than remaining straight.

I now suspect this may be a .pptx format issue, and I see from comments in the forums that the .pptx file format has been challenging from a compatibility perspective.

I am able to reproduce the issue in Open Office 3.2.0, 3.3.0 and Dev 3.4.0 DEV300m106 (Build: 9582).   This issue becomes obvious when comparing the Power Point and Open Office side by side in view slideshow mode. See the attached word document with screenshots.  In Figure 1, .ppt file is opened using Impress 3.2.0.  In Figure 2, same .ppt file is opened using Microsoft Office Power Point 2000.  Looking closely, Figure 1, Open Office footer is much larger than in Microsoft Power Point in Figure 2.  The page number is also shifted to the left comparing to Power Point.  It appears that Impress is using default standard font size/font format. That’s what Simon147 was talking about. 

Step to reproduce:
1.	Create a blank Power Point slide using default settings.
2.	Add footer via View Menu/Header and footer.
3.	Type in the word “Footer” in footer section and then click “Apply”
4.	Save as FooterTest.ppt file.
5.	Press F5 or Slide Show menu/View show to see the slide in full screen.  Take a screenshot.
6.	Now, open same FooterTest.ppt using Impress 3.2.0 or 3.3.0 or dev 3.4.
7.	Press F5 to see the slide in full screen.  Take a screenshot.
8.	Finally, compare two screenshots

My PC configuration:
	Microsoft Windows XP
	Version 2002
	Service Pack 3
	Intel® Core™ 2 Duo CPU
	T9300 @ 2.50 GHz
	2.49 GHz, 1.99 GB of RAM

Follow-up test:

I do not have the latest Microsoft Power Point, which allows user to customize footer font size, font style and position of the footer.  In my follow-up test, I’ll use the latest PowerPoint, change the font size (bigger and smaller) and move it to the left.  Then, compare PowerPoint and Impress side by side.

Customer Impact:

This bug is not a showstopper, but it is good to fix especially for users who use footer.  Open Office is competing with dominant player like Microsoft.  If their footer is working, this product should too.

Comments #7 and #8 do not appear to be related to Bug #115601.

I am able to reproduce the arrow/line issue between Power Point and Impress and can post additional instructions and screenshots if needed.  Thanks!

Bug description: Arrows created in PowerPoint change when opened in Impress

Steps to replicate:

1. Create a presentation in PowerPoint 2010
2. Draw a straight arrow at any angle that is NOT a multiple of 90 degrees (e.g. 45 degrees)
3. Save the presentation as a PowerPoint 2010 (pptx) file
4. Open the file in Impress

Expected result: The arrow is still straight

Actual result: The arrow is stepped 

Follow-up tests:

I tried tried some additional shapes:

* Straight lines (different angles)
* Stepped lines
* Stepped arrows
* Curves
* Rectangle

The bug appears to only apply to straight arrows at angles other than multiples of 90 degrees.

I also tried different file formats (all created in PowerPoint 2010)

* Presentation saved as PowerPoint 2010 (pptx)
* Presentation saved as PowerPoint 97-2003 (ppt)
* Presentation saved as OpenDocument Presentation (odp)

and the bug appears only when opening the pptx file.

Successfully replicated bug using OOO 3.3.0 Build: 9567 for Mac OSX and OOO 3.3.0 for Windows 7.  

System used:

2.4 GHZ core 2 duo processor
4 GB ram
Mac OSX 
Windows 7
MS PowerPoint 2007 (windows 7)
MS PowerPoint 2011 (Mac OSX)

Steps for replication:

1.	Create a new presentation in Microsoft PowerPoint
2.	Draw random arrows on one form  ( straight and at different angles eg. 30, 45 and 90)
3.	Draw random lines on another form
4.	Draw random arrows and lines on the final form
5.	Save presentation and close PowerPoint
6.	Open presentation in Open Office and observe the changes 
7.     Repeat tests in another platform

Arrows become stepped after document was opened in Open Office
The lines remained the same

Tried using other shapes as well and they were the same in both programs

After doing my own tests I then tested the files attached in the 1st report

The "straight" connector from PowerPoint is imported as "standard" connector in AOO.
