dist()

Is it possible to convert the measurement of dist() which is in pixles to mm?

I am trying to convert the distance of a line, point to point, into a metric measurement.

Thanks

Sam

It depends on the resolution (in the literal sense) of your monitor...
Ie. if it is 96dpi, 120dpi or something else.
That's dots (=pixels) per inch, so this value provides a base for the answer (you have to convert inches to millimeters, of course).

Thanks for the help,

Is there a way to detect the users screen resolution?

the problem isn't the screen resolution but the monitor! the you could have a 1024x768 screen in a 96dpi monitor or in a 120dpi

Assuming the device has the same DPI horizontally and vertically (true for most devices, fortunately), you can get it with:
int dpi = Toolkit.getDefaultToolkit().getScreenResolution();

Note that "resolution" is actually measured in DPI. Talking of 1024x768 as screen resolution is an abuse of language, that's actually the screen size...

int a = screen.width
int b = screen.height
