Padscaley; Padsendbyte; Padsetarea - Hand Held Products PadCom TT1500 User Manual

padScaleY

Scales a vertical pad coordinate to a desired DPI resolution. This function is designed to provide proper aspect ratio scaling
for accurate output.
Syntax
int padScaleY( int Y, int VertDPI )
Parameter
Y
VertDPI
Returns
Returns the vertical position scaled to the desired DPI.
See Also
padScaleX, padScaleDPI

padSendByte

This command sends a byte to the pad. This command can be used when the pad is in pass through mode to send data to
a device connected to the pass through port of the pad (if available). Using padSetOutTimeout (see page 3-55) you can
control how long this command will wait for the byte to be sent.
Syntax
BOOL padSendByte(
BYTE b
)
Parameter
b
Returns
If successful it returns TRUE, otherwise it returns FALSE.

padSetArea

This sets the minimum and maximum coordinates of the active pad area. This function causes clipping of points received
from the Transaction Team POS device's touch sensitive surface. All points that are outside of the specified range are
ignored. The coordinates given are not display coordinates, they are touch surface coordinates. In general, touch surface
coordinates are much higher in resolution than display coordinates. For example the Transaction Team 3100 Series touch
surface contains 903x1238 touch points while the Transaction Team 1500 display contains only 418x798 pixels, even though
they are about the same size in inches. You can use padGetPage (see page 3-19) to obtain the size and resolution of the
touch sensitive surface.
Description
An integer specifying the vertical coordinate to be scaled
