Syntax
Delphi
Function TPDFlib.DrawChord(XPos, YPos, Radius, StartAngle, EndAngle: Double; DrawOptions: Integer): Integer;
ActiveX
Function PDFlib::DrawChord(XPos As Double, YPos As Double, Radius As Double, StartAngle As Double, EndAngle As Double, DrawOptions As Long) As Long
DLL
int DLDrawChord(int InstanceID, double XPos, double YPos, double Radius, double StartAngle, double EndAngle, int DrawOptions);
Parameters
| XPos | The horizontal co-ordinate of the circle centre |
|---|---|
| YPos | The vertical co-ordinate of the circle centre |
| Radius | The circular arc radius in the current measurement unit |
| StartAngle | The start angle in degrees |
| EndAngle | The end angle in degrees |
| DrawOptions | 0 = outline, 1 = fill, 2 = fill and outline |
Return values
| 0 | The angle span or draw option was invalid |
|---|---|
| 1 | The chord path was drawn |
Remarks
Use DrawPie when the shape should close through the circle centre
