Assign Font Size in Pixels

You can set a font size of a label in the IDE to say 18 Pixels (as opposed to Points). How can I do this programatically?

.FontSize is in Points… per the LR
Pixels vs points depends on the device (retina etc)

A non-retina device is 1:1 points to pixels
A retina device is 2:1
(and for iOS the iPhone 6 is 3:1)

Use the TextUnits property using the FontUnits constants like this:

me.TextUnit = FontUnits.Pixel

for classic framework controls use TextSize and TextUnits

its in the LR for the respective controls
