Situation: I have some cheap Panasonic Plasma TVs that are used to display JPEGs off a USB stick. But whenever I "Export..." to a JPEG from Impress (or Draw) the JPEGs aren't recognised by the TVs. I used some Office Powerpoint presentations (pptx) to export some slides as JPEGs from Powerpoint and they work correctly on the TVs. But when I export the same slides from the same presentations in Impress they don't work on the TVs. So, I compared the JPEGs on this website - http://regex.info/exif.cgi - and found that the JFIF Resolution information was missing from the ones exported from Impress (and Draw) - the Powerpoint exports have "96pixels/inch" the Impress exports have "1pixel/none". I don't really know much about this or even if this is what is causing the Impress exports to not display on the TV. But any help would be great. (I have tried exporting other documents from Impress and Draw and have had the same result - the JPEGs not being recognised by the TVs. And all of the JPEGs exported from Impress display correctly on a computer - it's just these stupid cheap TVs.) Caleb
The information isn't filled correctly. So setting the issue to new. Confirmed it with LO 4.1.1.2 on Ubuntu 13.04 x86_64. So a platform independent issue

I have changed the compress method to always write 96 DPI as density - Please try with the LO 5 daily build (when available with this change) if it fixes the issue.
(In reply to Tomaz Vajngerl from comment #5) > I have changed the compress method to always write 96 DPI as density - > Please try with the LO 5 daily build (when available with this change) if it > fixes the issue. There's only one problem with your patch. Now DPI is *always* 96 no matter what you set it to. This makes the resolution option useless. Would be better to take the DPI from the options, 96 is default anyway.
