IManipulationProcessor::ProcessDown method (manipulations.h)
The ProcessDown method feeds touch down data to the manipulation processor associated with a target.
Syntax
HRESULT ProcessDown(
MANIPULATOR_ID manipulatorId,
FLOAT x,
FLOAT y
);
Parameters
manipulatorId
The identifier for the touch contact that you want to process.
x
The horizontal coordinate data associated with the target.
y
The vertical coordinate data associated with the target.
Return value
Returns S_OK on success, otherwise returns an error code such as E_FAIL.
Remarks
This method takes a timestamp using system time rather than from the touch hardware. To improve the experience in cases where performance is degrading you should use the ProcessDownWithTime method.
