Re: Size of screen diagonal?
I'm not really sure how you would go about this. For instance: I have a 2006 iMac that uses both its in-built monitor and another second one. System Info tells me that my in-built display is 20.1 inches, but nothing about my other one beyond the fact that it is a VGA display. However, my Xubuntu machine does report the dimensions of the monitor connected to it accurately (NEC Corporation 21"). Richmond.

We make vision testing software. This requires very accurate representations of visuals on screen. For this we ask the user to enter in the diagonal screen size. Because this is a vertical app, that comes along with installation services, this is normally done by the installer. You will get accurate sizing using this method. For the wider spectrum of users, we can get those values if you have control over the range of devices they are using. For one app, iOS only, we ask them to select the device they are using. We still use diagonal screen size as the metric for the math under the hood. For truly horizontal markets, having them enter in the value may or may not be acceptable. If the tool requires the utmost in accuracy, then the user may be asked. For UI layout purposes, pixelDensity() may be enough to get you through.

Given the wide and growing variety of screen ratios, diagonal screen dimensions are less useful for this task. I think pixelDensity of what you're looking for, but be forewarned: I spent an afternoon some time ago measuring a variety of on-screen elements across all the devices in my test pool, using a physical ruler placed on the screen. What I found is that LC seems to do as good a job as Android itself in attempting to maintain consistent sizing among such a wide range of physical display characteristics (dot pitch, etc.). Not surprising, since AFAIK LC uses the recommended OS APIs for its resolution independence. But the downside is that I was able to measure differences in even the most standard elements like the status bar. Not much, just a millimeter or two across some devices. So if a fairly-close-but-not-perfect rendering will suffice, I think the pixelDensity function will guide your metrics. -- Richard Gaskin Fourth World Systems Software Design and Development for the Desktop, Mobile, and the Web ambassa...@fourthworld.comhttp://www.FourthWorld.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
