--- Comment #30 from Armin Le Grand <armin.le.gr...@me.com> --- Hi John, thanks for bringing this up. Just installed irfanview and did the following: - opened jpeg with inrfanview - copied to clipboard - pasted to new draw, saved draw, extracted pic from ODF -> indeed a PNG The problem is not that "OOo accepts it as a PNG, and stores it as a PNG". AOO accepts it as RGBA bitmap data (in this case PNG as clipboard format). AOO does not get the original jpeg file via the clipboard (and I thin this is not offered - if someone knows better, please describe here) and thus *cannot* remember it for saving it. AOO gets a selection of clipboard format and uses the one with the highest quality (this is the best it can do - no reason to change that). Same at save time: AOO chooses the most lossless format (also the best AOO can do - also no reason to change that), in this case of data adding - as said - it has no access to the original data. When doing the following: - new Draw - insert jpeg of your choice - saved draw, extracted pic from ODF -> stays original data In this case AOO *has* access to the original jpeg data and does all correctly. In this case it 'knows' that it cannot increase/save quality when using PNG, so the original jpeg is used (as expected). So the problem is the method of insertion which in turn defines what information AOO *can* have about the data it gets. Unfortunately the user has to know here what he is doing. Copy/paste from pic viewers or editors (which may already have altered the data) does not contain the original data, so I do not think there can be done something here. Of course when someone knows how to make e.g. irfanview to deliver the URL to the original file in the clipboard or maybe knows that it's included there, please speak out. -- You are receiving this mail because: You are on the CC list for the bug.
