padGet

Receives new data from the pad by checking for and returning the last horizontal/vertical coordinates and pen status. A pen
status of 1 indicates the continuation of a line (lineto(x,y )), whereas a 0 represents the beginning of a stroke (moveto(x,y)).
NULL pointers may be passed as any of the parameters to suppress gathering of the associated data. Note that if no pen
activity occurred since the last padUpdate, the function returns FALSE and does not alter the values pointed to.

Syntax

BOOL padGet (
int *XPosition,
int *YPosition,
int *Pen
)

Parameter

Description

XPosition

Pointer to an integer to hold the new horizontal coordinate of the pen

YPosition

Pointer to an integer to hold the new vertical coordinate of the pen

Pen

Pointer to an integer to hold the new pen status (0 = moveto, 1 = lineto)

Returns

Returns TRUE if new pen data was received, FALSE otherwise.

padGetAllMagCardTracks

Returns data captured from all tracks on a magnetic card, if available. A card must have been swiped prior to executing this
command, otherwise it returns zero. The TrackXSize parameters should contain the maximum buffer sizes for each track
before the call, and after will contain actual track sizes after the call. The card reader must be reset using

padResetMagCard

before calling this command. Refer to page 5-1 for sample code that describes how to read the MSR.

Syntax

BOOL padGetAllMagCardTracks(
BYTE *Tracks,
char *Track1,
WORD *Track1Size,
char *Track2,
WORD *Track2Size,
char *Track3,
WORD *Track3Size
)

Parameter

Description
