Presentation (one slide) that illustrates the incorrect flipping of text in a square.  Also illustrated is incorrect flipping of rotated shapes containing text: the text sometimes falls outside the shape after the flip operation.

Problem description: 
(This problem is related to, but different from, bug 50435.)
When a shape containing text is flipped horizontally or vertically, the effect on the text is not correct.

Steps to reproduce:
1. In a new presentation, select a shape and draw it on the slide.
2. With the shape selected, click on the Text tool and enter some text into the shape.
3. Select the shape containing the text, then choose Flip > Horizontal from the right-mouse menu.  The text will remain unchanged: ordinary letters reading left-to-right.
4. With the shape selected, choose Flip > Vertical from the right-mouse menu.  The text will be rotated 180 degrees (ordinary letters that read left-to-right if you stand on your head).

Current behavior:
Text that is flipped horizontally or vertically is not correct.  The letters are not mirrored.

Expected behavior:
Flipping text horizontally should cause each letter to be reversed left-to-right, and those reversed letters should be printed right-to-left.  Flipping text vertically should cause each letter to be inverted top-to-bottom, and those inverted letters should be printed left-to-right.  In either case the letters should be mirror-images of ordinary printed letters.

Platform (if different from the browser): 
MS Windows 7 Pro, v6.1.7601 SP1, on Dell Inspiron 620 (Core i5-2320).  Built-in Intel HD graphics.

The problem with flipped text still exists in 3.5.5.3 under Windows.  Rotated shapes are now flipped correctly, but the text is still not mirrored.

Comment 2 David F Smith 2012-11-19 22:35:38 UTC

This problem still exists in 3.6.3.2 (Build ID: 58f22d5), under Win 7 Pro (v6.1.7601).

Comment 3 Jorendc 2012-12-28 00:38:45 UTC

Thanks fore reporting!

I can reproduce using Mac OS X 10.8.2

LibreOffice 4.1.0.0.alpha0+ (Build ID: 699132c269a6c6d9e815fc582e2e6a106e46923)
TinderBox: MacOSX-Intel@1-built_no-moz_on_10.6.8, Branch:master, Time: 2012-12-27_01:05:51

Comment 4 David F Smith 2013-07-18 15:54:11 UTC

For the record, this problem still exists in 4.0.4.2, tested under Windows 7 Professional (6.1.7601 Service Pack 1).  The text in a horizontally flipped shape is unchanged; the text in a vertically flipped shape is rotated 180 degrees.  Correctly flipped text would be mirrored, either horizontally or vertically.

Is this a duplicate of Bug 35913?

Comment 6 David F Smith 2015-03-12 03:43:38 UTC

The problem still persists in Version 4.4.1.2
(Build ID: 45e2de17089c24a1fa810c8f975a7171ba4cd432)
under Win 7 Pro (v6.1.7601).
There seem to have been minor changes in where the text in a rotated shape appears after flipping, but it can still fall outside the shape, as in my original report.  And the fundamental problem, that the text is not mirror-imaged, is still there.

To answer Timur's question, yes, this appears to be a duplicate of Bug 35913.  Please note, however, that I disagree with that reporter's position that the text should always be readable (e.g., left-to-right for English).  I think that flipping, which is mirror-imaging, should operate on text the same as it does on shapes.  After all, the person performing the operation may wish to treat the text characters as shapes and flip them.
