How can I detect if a user has a retina display in Java? I am already aware of detecting the scale factor using Toolkit.getDefaultToolkit().getDesktopProperty("apple.awt.contentScaleFactor"), but java won't let me convert the returned value into an int. I'm wondering how I can convert that into an int, or another way to detect retina displays.
I would get the value this way -
public static boolean hasRetinaDisplay() {
Object obj = Toolkit.getDefaultToolkit()
.getDesktopProperty(
"apple.awt.contentScaleFactor");
if (obj instanceof Float) {
Float f = (Float) obj;
int scale = f.intValue();
return (scale == 2); // 1 indicates a regular mac display.
}
return false;
}
