Description

Object

Abstract object.

Point

Pointer to an array of points which controls the spline’s path depnding on the spline type. The number of points should be:

( puDegree[ 0 ] + puDegree[ 1 ] + … + puDegree[ nSecCount – 1 ] ) + 1

nPointCount

Number of points in the points

Pen

VECTORPEN structure that contains information about the pen to use when drawing the vector spline object

dwFlags

Flag that indicates the mode in which to draw the spline. Possible values are:

 

Value

Meaning

 

VECTOR_SPLINE_FITPOINTS

Sets the spline mode to Fit Points. This is the default.

 

VECTOR_SPLINE_CONTROLPOINTS

Sets the spline mode to Control Points.

Comments

The spline can be drawn in two modes:
