◆ GetPoints()

virtual SDKResult SDK_CALLTYPE GetPoints ( SDKUInt32  index,
SDKUInt32  count,
PointType  type,
void *  points 
) const
throw (
)
pure virtual

Gets the ith IPoint from the PointCollection. The first Point in the PointCollection has index 0, and the last Point has index equal to PointCount - 1.

Parameters
index[in] An index of the requested element.
point[out] Address of variable that receives the pointer to IPoint interface.
Returns
kSDKResult_Succeeded
kSDKResult_NotImplemented
kSDKResult_NotExist

Populates an array with references to points.

Parameters
index[in] An start index of the requested elements.
count[in] Number of requested elements.
point[out] A pointer of an array of pointers to IPoint interface that receives requested elements.
Returns
kSDKResult_Succeeded
kSDKResult_NotImplemented
kSDKResult_NotExist

Copies some points to an existing array of point structures.

Parameters
index[in] An start index of the requested elements.
count[in] Number of requested elements.
type[in] The data type of output points.
point[out] A pointer to an array of point structures that receives requested elements.
Returns
kSDKResult_Succeeded
kSDKResult_NotImplemented
kSDKResult_NotExist
