Hi, Dennis E. Hamilton schrieb: Regina, Thanks for the test document. The following applications open that document exactly the same way: * Microsoft PowerPoint 2007 (after going ahead when the document is found not to be ODF 1.1) * LibreOffice 3.3.2 on Windows 8 * Apache OpenOffice 3.4.1 on Windows XP SP3 * Microsoft PowerPoint 2013 on Windows 8 * LibreOffice 4.0.1 on Windows XP SP3 Slide 1 is with a big almost-isosceles triangle near the upper left Slide 2 has that triangle rendered much smaller (and the geometry doesnot seem to be quite proportional to the large one) In Apache OpenOffice it is 1/10, but you need 3000% zoom to measure it. Slide 3 has that big triangle translated higher and to the left into the upper left corner, with the left-most apex ouside the left side of the frame (and clipped in the slideshow). They act as if svg:viewBox="0 0 21600 21600" was given. If Calligra had the same results, I would have suggest to specify, that this is the default in case the attribute svg:viewBox is missing. But because Calligra does it different, I have no simple proposal what to do. I think, that the attribute svg:viewBox cannot be really optional but need a default, because many values in the enhanced geometry are defined with reference to svg:viewBox. Kind regards Regina
