Description |
|
Object |
Abstract object. |
|
Point |
A VECTORPOINT structure that contains the vertex of a vector arc object, about which the arc sweeps. |
|
Pen |
VECTORPEN structure that contains information about the pen to use when drawing the vector arc object. |
|
Radius |
Length of the radius of the vector arc object. This value is in logical units. |
|
StartAngle |
The angle at which to begin the vector arc. Values should be between 0 and 360 degrees. Values less than 0 and greater than 360 will be modified internally. |
|
SweepAngle |
The angle through which to sweep the vector arc. Values should be between –360 and +360 degrees. Positive angles will be drawn in a counter-clockwise direction from StartAngle. Negative angles will be drawn in a clockwise direction. |
Comments
nSize of the Object member must be the sizeof this structure.
nType of the Object member must be VECTOR_ARC.
pVECTORARC is a pointer to a VECTORARC structure.
The diagram below gives a graphical representation of of the Point, Radius, StartAngle and SweepAngle parameters.
