InsertPenDataStroke

2.0

Inserts a stroke into an existing HPENDATA object.

int InsertPenDataStroke( HPENDATA hpndt, UINT iStrk, LPPOINT lppt, LPVOID lpvOem, LPSTROKEINFO lpsiNew )

Parameters

hpndt

Handle to the HPENDATA object that receives the inserted strokes.

iStrk

Zero-based index of the stroke at which the new stroke is to be inserted. If this value is IX_END, the stroke is appended at the end of the HPENDATA memory block.

lppt

Pointer to a buffer containing the points to be inserted.

lpvOem

Pointer to a buffer of OEM data. This value can be NULL only if the pen data object does not have OEM data or a PENINFO structure.

lpsiNew

Pointer to the STROKEINFO structure containing information about the stroke.

Return Value

Returns PDR_OK if successful; otherwise, the return value can be one of the following negative values:

Constant	Description
PDR_COMPRESSED	Pen data is compressed.
PDR_ERROR	Parameter or other unspecified error.
PDR_MEMERR	Out of memory.
PDR_STRKINDEXERR	Invalid stroke index.
PDR_TIMESTAMPERR	Timing error.
PDR_VERSIONERR	Could not convert old pen data object.

Comments

InsertPenDataStroke inserts an entire stroke into an HPENDATA object. Use InsertPenDataPoints to insert points into a particular stroke.

The inserted stroke assumes the default pen-tip attributes. SetStrokeAttributes should be called after inserting the stroke to change such stroke attributes as the pen-tip characteristics or user data.

The calling application must ensure that lppt and lpvOem are valid, and that the points in the stroke that is being added have compatible scaling modes.

Attempting to insert an empty stroke simply returns PDR_OK.
