Your hyperlink does not link to any file, only a website. Please give the correct link. Set status to NEEDINFO. Please set it back to UNCONFIRMED once you have provided requested informations. Best regards. JBF I've rehosted the file here: http://web.media.mit.edu/~mhirsch/ICCP14_upload.pptx You can also click the "save" link at the top of the first website in order to save the file. TESTING on Ubuntu 12.04.4 + LO 4.3.0.3 (In reply to comment #2) > I've rehosted the file here: > http://web.media.mit.edu/~mhirsch/ICCP14_upload.pptx Is it possible to reproduce the bug with a presentation smaller than 45MB? I'd try deleting all slides after #5 and see if the problem remains. (In reply to comment #0) > the image of the sensor on the right side of slide 5 shows up as an empty > box called "Picture 16". CONFIRMED. I see an empty element for Picture 16, and a white question mark inside a grey circle (is the latter image part of the original file?) > In the "classic" libreoffice missing picture bug the picture goes missing > after a save operation, and it is found that the picture is no longer > contained in the presentation archive or xml. However, in this case the > image is in the presentation (it is rendered properly on slideshare and in > powerpoint 2010) but it does not show up in libreoffice. Perhaps the cause > is related, but this seems more deterministic and perhaps easier to debug. This sounds similar to bug 81517, but that's a binary xls and this an ooxml pptx. Narrowing-down the test case to a minimal reproducible file would greatly accelerate our ability to track down this bug. I won't have access to powerpoint for another week or so, but I will try to reduce the size of the slide set next time it becomes available. FWIW, I see the broken image in various LibreOffice versions back to bibisect-43all oldest. My attention goes to ppt/media/image21.png embeddedin the .pptx: "The GNOME imager viewer" 3.4.2, as delivered with debian-wheezy 64-bit complains: Could not load image "image21.png". Fatal error reading PNG imagefile IDAT: CRC error while Beyond Compare version 3.3.10 (a proprietary file comparison utiltity from Scooter Software) complains: ppt/media/image21.png bad CRC 1967134b (should be c6c34b02) So, Matt, What program created ICCP14_upload.pptx? If other than LibreOffice, I lean toward resolving this report NOTOURBUG. If you used LibreOffice to create the .pptx, I would ask you to do some things. (*) Did something bad happen between your upload and my download? My ICCP14_upload.pptx has an md5sum ad27101012364074ca777d7acb350f72. Is your file the same? (*) Can you view the image in a file viewer? (*) What is the md5sum of the image file you started with? The image21.png that I extracted has md5sum 58c507f7bc27e4ab9ca5d0d0b8f87d38. If they are the same, then LibreOffice is again off the hook, I think. If they are different, and if you used LibreOffice to create the .pptx, we need instructions on how to create a .pptx with the error: each keystroke and each mouseclick would be good. It was created in powerpoint. I'm not sure how the image would have been corrupted, but I can see how that would lead to unpredictable behavior. I guess you can close the bug. Thank you, Matt, for you prompt response. I am setting bug status RESOLVED NOTOURBUG. One has to wonder what kind of corruption lets slideshare and powerpoint show the image, but I am not even close to being able to look into that. |
