I didn't even have to think, I looked it up and it wasn't there. :) But since you're (presumably) about to add the term, is there a better word for it? Something indicating "text" somehow? Anyone looking for a property like that would probably do a search for "text". -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

If I understood you correct, things even get crisper and not blurred with Hi-DPI enabled on a Hi-DPI monitor and keep as they are on a standard monitor. So my conclusion would be to enable it always by standard (since it is anyway standard on OS X) Yes - this is the ideal situation :) What could be a reason not to enable Hi-DPI scaling on Windows or with other words, why is it an option? Ah - well - the APIs we currently use on Windows are a bit of a dinosaur in terms text rendering. We still use 'GDI' which has the unfortunate problem that text does not linearly scale. What this means is that the size of a piece of text rendered with GDI at scale factor 1.0 is not necessarily the same as the same text rendered at scale factor 2.0. This is down to the TrueType hinting and other methods it employs which you cannot actually turn off (this hinting can be quite aggressive - its goal was to ensure text rendered at low screen resolutions was still highly readable without anti-aliasing - and tends to alter the horizontal width to varying degrees for different fonts). We've not actually managed to find a way to solve this problem 'well' yet - particularly as we still have to support XP (given its market share is still quite considerable!). So, you do need to check your app in Hi-DPI mode on windows (by adjusting the text scale factor in settings, as previously mentioned) and make sure it still looks the way you need it to. You *can* try and set the 'useIdealLayout' property of the stack if there are visual problems - this will make the text render in the appropriately 'linearly scalable' way. However, it does have a performance and visual difference impact - the text will be slightly fuzzier, and will take a little longer to render. Hope this helps!
