The QMLProfile height is specified as ~2/3 (actually 0.66) width in DiveDetailsView.qml. In order to produce an even margin around the profile, the scaling factor reduction for height needs to be 3/2 times that for width. MarginFactor is specified as 0.013 to approximate the margin calculated by commitsef653b4and7e2898dfor my Galaxy S6. MarginFactor = margin / width = 18 / 1365 = 0.132 Signed-off-by: Rick Walsh <rickmwalsh@gmail.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
