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:
Fit Points: The spline path MUST pass through each and every point specified.
Control Points: The points are used to control the spline path, but not necessarily pass through all of them.
