Arguments

selectedPoints Pointer to an array in which the position numbers of the points selected are returned in ascending order.
pSelectedPointNum Pointer to the int variable that accepts how many points were returned in selectedPoints.
maxPointCount Maximum number of points after resampling.
maxStrokeCount Maximum number of strokes after resampling.
strokes Raw input stroke data.
threshold Resampling threshold.
buffer Pointer to the memory region that will be used during processing.

Return Values

Returns TRUE if resampling is successful and set of points with a valid length is obtained.

Description

Uses the resampling algorithms to resample stroke data. The result of this function returns in a u16 array, selectedPoints, which is the position number of the points in strokes->points that remain after resampling. The results also return in pSelectedPointNum, which is the number of points. In the array, the numbers are stored in ascending order. You must allocate a size of at least maxPointCount for selectedPoints.

buffer provides a pointer to the work area used for the resampling process. The work area requires sizeof(int)*maxPointCount. Allocate this beforehand.

For details on the resampling algorithms and thresholds, see PRCResampleMethod.

This function is not required for normal pattern recognition procedures. They are called automatically from PRC_InitInputPattern*.
