[Oberon] FPGA - OberonV4 Dialogs

The values are stored in a device-independent form; they are measured in 1/36000 mm.

You have to divide them by a scale factor dependent on your device:

300 dpi printer           3048
83 ppi screen            10000 
American points       12652 (TeX)
Typesetting points  12700 (pdf/postscript)
Continental Didot    13500
mm                              36000
inch                           914400

As typical monitors have ~83..93 ppi you normally divide the value by 10’000 to convert to pixels.

Eg the monitors mostly offered in stores today are 24“ in diagonal with 1920x1080 pixels. This results in 92 ppi. For this screen you could divide the values by 9962 to have an absolutely accurate representation of the Dialog. But round 9962 up to 10‘000 and you‘re fine.
