Creates an ellipse, a circle or an arc.
Syntax: |
FWiz2DImage.DrawEllipse(center, sizex, sizey = 0, startAngle = 0, stopAngle = 0, rotAngle = 0, flags = DlxApp.ELLIPSE_CCW)
|
Parameters
Parameter |
Description |
center |
A DlxPoint object with the coordinates specifying the center of the ellipse. |
sizex |
A positive value that defines the radius of the circle or the half length of the horizontal axis of the ellipse. |
sizey |
A positive value defining the half length of the vertical axis of the ellipse. If zero is specified, sizey is set equal to sizex. |
startAngle |
The angle, in degrees, of the arc start. |
stopAngle |
The angle, in degrees, of the end of the arc. |
rotAngle |
The angle, in degrees, of rotation of the ellipse. |
flags |
A combination of the following values:
Value |
Meaning |
DlxApp.ELLIPSE_CW |
The arc is drawn clockwise. |
DlxApp.ELLIPSE_CCW |
The arc is drawn counterclockwise. |
DlxApp.ELLIPSE_EANGLE |
The startAngle and stopAngle values are referred to the ellipse otherwise they are referred to the circle. |
DlxApp.ELLIPSE_CLOSED |
The arc is closed with segments in the center. |
DlxApp.ELLIPSE_CHORD |
The arc is closed to the chord. |
|
Return Value
If an error occurs it returns false otherwise it returns true.

Copy code

function OnBuild2DImage()
{
var ctx = FWiz.Get2DImageCtx();
var pen = FWiz.GetPenStyle(0);
pen.SetStyle("Marker pen blue");
ctx.SetPenStyle(pen);
var brush = FWiz.GetBrushStyle(0);
brush.SetStyle("Yellow");
ctx.SetBrushStyle(brush);
ctx.DrawEllipse(new DlxPoint(0, 15), 10);
ctx.DrawEllipse(new DlxPoint(0, 0), 40, 10);
ctx.DrawEllipse(new DlxPoint(0, -15), 30, 20, 0, 45, 0, DlxApp.ELLIPSE_CLOSED);
