Sample PPT (saved from previous PPT in PowerPoint)
The problem is with the unusual key times. Dumping animation data gives the following: - good: ... <animate fill="hold" dur="0.5" calcmode="linear" valueType="number" keyTimes="0.000000;1.000000;" values="#ppt_x;#ppt_x" additive="replace" attributeName="ppt_x" paragraph 0, 5 characters target=""/> <animate fill="hold" dur="0.5" calcmode="linear" valueType="number" keyTimes="0.000000;1.000000;" values="1+#ppt_h/2;#ppt_y" additive="replace" attributeName="ppt_y" paragraph 0, 5 characters target=""/> ... - bad: ... <animate fill="hold" dur="0.5" calcmode="linear" valueType="number" keyTimes="1.000000;-1.000000;" values="#ppt_x;#ppt_x" additive="replace" attributeName="ppt_x" paragraph 0, 5 characters target=""/> <animate fill="hold" dur="0.5" calcmode="linear" valueType="number" keyTimes="1.000000;-1.000000;" values="1+#ppt_h/2;#ppt_y" additive="replace" attributeName="ppt_y" paragraph 0, 5 characters target=""/> ... Animations only permit key times in the range of [0, 1], and the first entry has to be 0. Solution: if the key times are outside the range, normalize key times during import, at least both for PPT and PPTX formats. Note: in OOXML format the key times are stored in element 'tav'.

Dump of different animation properties
Attaching four dumps of four different cases:
- flyin_good.xml: PPT as created in Impress,
- flyin_origPP.xml: PPT as created in PowerPoint,
- flyin_bad.xml: PPT created in Impress, then roundtripped in PowerPoint,
- flyin_PPfixed.xml: PPT created in Impress, then roundripped in PowerPoint, while setting the same animation again.
Out of these only the third (flyin_bad.xml) isn't played correctly in Impress.
Nevertheless, the original PPT produced by Impress might contain attribute combinations PowerPoint isn't expecting, hopefully the dumps shed some light on that.
Aron Budea committed a patch related to this issue. It has been pushed to "master": http://cgit.freedesktop.org/libreoffice/core/commit/?id=4e207c2e17d75a3cb7b6b72690375279be40d64a tdf#116899: normalize key times during PPT import if needed It will be available in 6.1.0. The patch should be included in the daily builds available at http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: http://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback. |
Created attachment 141228 [details] Sample ODP - Add Fly-in animation to a text box in Impress, and save it as PPT. - Open the PPT in PowerPoint, and simply save it. - Open the PPT in Impress again, and play the slideshow. => There's no animation for the text box. In PowerPoint the animation still appears in the very same file. Setting the same animation again either in PowerPoint or Impress will play the animation in Impress again. Attaching a sample ODP, the ODP saved as PPT in Impress 6.0.3.2, and the PPT saved again in PowerPoint. Observed using LO 6.0.3.2 & 3.5.0.3 / Windows 7.
