[upstream] Importing pptx files into Impress discards crop information of all images

[Lyle Gordon]

Binary package hint: libreoffice

Upon loading a pptx file into Libreoffice Impress from MS Office 2007 or 2008 (prepared on windows 7) all the cropping information of the included images is lost. The images resort to their full dimensions and are often scaled anisotropically to fit into their previous dimensions. The dimensions of the images are maintained but the crop information is lost. Other than this bug everything seems to import well. It would be great o have this work.

Thanks very much,
Lyle

Thank you for your bug report. Could you maybe attach a sample pptx file showing this issue and/or a screenshot showing the problem? Thanks!

I believe the difference between cropped and uncropped (and potentially the line that is being ignored) is:

<a:ext cx="2796737" cy="6065838"/>

in the file /ppt/slides/slide1.xml

Another remark: The thumbnailer from the libgsf project produces a correct thumbnail.

Thanks for the files, I can confirm the issue both with openoffice and libreoffice (3.3.0 rc 4). I opened an upstream bug report about the issue, you can track it and make comments at: https://bugs.freedesktop.org/show_bug.cgi?id=33361

should say reproduced this on rc4

Lyle, as a workaround, could you try saving to .ppt and then reproduce the same issue ? I'll will ask someone else to do the same but if you get to it faster than me that would be great.

[Lyle Gordon (lgordon)]

Saving the file as a ppt (attached) using Powerpoint 2010 in Windows XP and then opening it in Libreoffice 3.3 does solves the cropping issue. However this doesn't completely solve the problem as there are some new features that are lost when converting to the old ppt format.

Libre Office 3.3.1.2 on Mandriva 64bit not saves crop information in pptx format. To reproduce this problem start this attachment, save as pptx and open then with MSoffice 2007. MS office 2003 with compaibilith extension can not open this file.

in Libreoffice 3.4 beta 5 works ok on Mandriva 64 bit and Windows 32 bit. I hope it fixed. Thanks!

For original report (Marcel's), I tested his document and results are:
3.4.3 WORK
3.3.4 FAIL

Anyway, if it seems no known specific fix, please use WORKSFORME instead of FIXED. Thanks.
