I have ported a QuickBasic program from the Macintosh that measures
bone lengths from hand x-rays using a digitizing pad. The problem that
I am having is that on the macintosh, the program could read the
coordinates fromt the digitizing tablet using the QuickBasic MOUSE
function with a reasonable degree of accuracy. I have downloaded
QBasic libraries from simtel that allow me to take coordinates from
the tablet's mouse driver (I'm using QuickBasic 4.5 on my pc), but the
resolution that I can achieve using this method is pathetic. The
digitizing tablet that I am using is a Summagraphics Summasketch II
Plus (connected to com1). It comes with a microsoft compatible mouse
driver, as well as a program called mmtest.exe that prints a stream of
xy coordinates and button positions to the screen.
I have ordered a technical manual from Summagraphics (this is the only
help they would give), but if anyone has experience programming with a
Summasketch tablet, I would appreciate any help you could give (I am
not a programmer).
