bnc#862510: PPTX import: Wrong text vertical adjustment inside shape.
When alignment is not specified, it should be set to the
default "left" value just on time, when properties are
pushed to the property set, otherwise uninitialized value
is better.

Text anchor settings in Impress and PP

In PP the alignment of the textbox is Top, but it's opened in Impress as if it was Top Centered in PP.

The master slide

And finally i have reached this one. I think the problem comes from the master slide (as shown in my picture), if there i change the alignment to left, everything fine, so there is a file open problem with the setting priority. PP overrides the master slide setting Impress does not, however should. Hopefully if i change the order of the property applying that might be the solution.

I think regression flag can safely be removed. It just happened to look better when the default of left align was forced on it.

The problem is that the slide should not be inheriting the textbox from the master. (For example, if MS Office adds a fill to the master's subtitle textbox, slide1 doesn't get that fill.) The title textbox in the slide mirrors the master, but not the subtitle textbox. [Problem already seen in LO 3.5 bibisect.]

The issue seems to be that master is
    <p:ph type="subTitle" sz="quarter" idx="1"/>
but the slide is different ID
    <p:ph type="subTitle" sz="quarter" idx="4294967295"/>

If I set the slide's idx to 1, then MS 2010 opens like LO - i.e. the master's textbox settings apply to the slide's textbox.


There was major re-work done in the LO 4.4-ish timeframe.

    bnc#821916: Better algorithm to find placeholder shape.

// Function to find placeholder (ph) for a shape. No idea how MSO implements
// this, but this order seems to work quite well
// (probably it's unnecessary complicated / wrong):
// 1. ph with nFirstSubType and the same oSubTypeIndex
// 2. ph with nFirstSubType
// 3. ph with nSecondSubType and the same oSubTypeIndex
// 4. ph with nSecondSubType
// 5. ph with the same oSubTypeIndex


Forcing an idx reference to only match a master with the same idx fixed the bad textbox inheritance problem (from slideLayouts) and didn't cause any real unit test failures, but it did cause the blue colour (from slideMasters) to disappear in this examples test.pptx. [Obviously not a complete or safe solution.]
