The functions listed below add, delete, or copy coordinate data to and from an HPENDATA object.
Function
| Description
|
AddPenDataHRC
| Copies the pen data from an HPENDATA object to an HRC object. This function provides the means for deferred recognition. An
application can gather pen data into an HPENDATA block, manipulate or store it if desired, then later copy the data to an HRC object for recognition.
|
AddPointsPenData
| Appends a set of points, including a STROKEINFO structure and any corresponding OEM data, to an HPENDATA object.
|
ExtractPenDataPoints
| Copies points and OEM data from an HPENDATA block to supplied buffers. The application can convert the points to screen
resolution with the TPtoDP function to reduce the buffer size. The application can also optionally
delete these points from the original pen data.
|
ExtractPenDataStrokes
| Copies selected strokes from an HPENDATA block, optionally creating a new HPENDATA block containing the copied strokes. ExtractPenDataStrokes can optionally delete the original strokes.
|
GetPointsFromPenData
| Retrieves information from an HPENDATA object in a way similar to the GetPenDataStroke function. However, GetPointsFromPenData copies the required data to buffers supplied by the application rather than
simply returning pointers to the original data in the global heap. Therefore,
the application need not call BeginEnumStrokes and/or EndEnumStrokes when using GetPointsFromPenData.
|
InsertPenData
| Merges two separate HPENDATA objects into a single object.
|
InsertPenDataPoints
| Inserts points into the stroke of an existing HPENDATA object. InsertPenDataPoints automatically updates the stroke and pen data headers.
This function can adversely affect recognition accuracy for data that must
later be recognized.
|
InsertPenDataStroke
| Inserts an entire stroke into an existing HPENDATA object. InsertPenDataStroke automatically updates the stroke and pen data headers. The ink of the
inserted stroke has default color and width. To change these attributes, call SetStrokeAttributes after inserting the stroke.
|
PenDataToBuffer
PenDataFromBuffer
| Copy an HPENDATA object as sequential data from and to a buffer. PenDataFromBuffer creates and loads an HPENDATA object with the data from the sequential buffer created by PenDataToBuffer. These functions are used to transfer pen data to and from a file or the
clipboard.
|
RemovePenDataStrokes
| Deletes a contiguous set of strokes from an HPENDATA object.
