Convert pixels to mm [message #488657]

Hi,

In GMF we are doing pixel to mm or inches conversion based on the DPI (Device#getDPI()). However, this doesn't depend on the screen resolution. Hence, we'd like to try something that does consider the screen resolution. Is there a utility method that could convert pixel to mm acounting for screen resolution? Otherwise, perhaps there are utility methods to determine physical screen size and the resolution?

Thanks.

Cheers,
Alex

Hi, sorry for the late response,

Computing the physical screen size should just be "width =
monitor.getBounds().x * Device.getDPI().x" and "height =
monitor.getBounds().y * Device.getDPI().y". Is this enough to do what you
want?
