You can set the following three types of joint styles for the
jointStyle
parameter:
■
round
( default )
■
miter
■
bevel
The following example demonstrates the differences between each of the three joint styles.
To set different joint styles:
1. Create a new Flash document and save it as jointstyles.fla .
2. Add the following ActionScript to Frame 1 of the Timeline:
var lineLength:Number = 100;
// miter
this.createEmptyMovieClip("miter_mc", 10);
miter_mc.lineStyle(25, 0xFF0000, 100, true, "none", "none", "miter",
25);
miter_mc.moveTo(0, lineLength);
miter_mc.lineTo(lineLength / 2, 0);
miter_mc.lineTo(lineLength, lineLength);
miter_mc.lineTo(0, lineLength);
miter_mc._x = 50;
miter_mc._y = 50;
var lbl:TextField = miter_mc.createTextField("label_txt", 10, 0,
line 20, lineLength, 20);
lbl.autoSize = "center";
lbl.text = "miter";
// round
this.createEmptyMovieClip("round_mc", 20);
round_mc.lineStyle(25, 0xFF0000, 100, true, "none", "none", "round");
round_mc.moveTo(0, lineLength);
round_mc.lineTo(lineLength / 2, 0);
round_mc.lineTo(lineLength, lineLength);
round_mc.lineTo(0, lineLength);
round_mc._x = 200;
round_mc._y = 50;
var lbl:TextField = round_mc.createTextField("label_txt", 10, 0,
line 20, lineLength, 20);
lbl.autoSize = "center";
lbl.text = "round";
// bevel
this.createEmptyMovieClip("bevel_mc", 30);
bevel_mc.lineStyle(25, 0xFF0000, 100, true, "none", "none", "bevel");
bevel_mc.moveTo(0, lineLength);
bevel_mc.lineTo(lineLength / 2, 0);
bevel_mc.lineTo(lineLength, lineLength);
bevel_mc.lineTo(0, lineLength);
bevel_mc._x = 350;
bevel_mc._y = 50;
