padSetPadOffset

This command sets the offset value of the
horizontal and vertical points retrieved from
the Transaction Team device's touch surface
area when mapping the device's smaller
surface area to a larger surface area when in
PenWare100 emulation mode. For example,
say a touch surface area is approximately
9.5x5.5 centimeters in size. The Transaction
Team 1500's touch surface area is
approximately 7x3 centimeters in size. To
center the smaller Transaction Team 1500's
touch surface area within the larger touch
surface area you would use an offset of
187x220. To place the Transaction Team
1500's touch surface area at the lower right
corner of a larger touch surface area you
would use an offset of 357x441. To place the
Transaction Team 1500's touch surface area
at the upper left corner of a larger touch
surface area you would use an offset of 0x0,
meaning no offset is used. This command
only works if the Transaction Team device is
in emulation mode. If the device is not in
emulation mode this command has no effect.
To put the device into emulation mode use the padSetPadMode command (see page 3-57).
