  1. 1 twip = 1/20 point = 1/1440 inch
    The number of pixels in a twip depends on the device's resolution.
  2. [number of pixels in one twip] = [device dots per inch] / 1440
  3. Look http://forum.delphiarea.com/viewtopic.php?t=741 for the answer.

2. getdevicecaps + monitor handle or use global Screen variable
3. analogically, use get instead of set and query for it.

funny is that every bit of it is cleared out in help available freelly to anyone in delphi's help menu.
