function get_startHeadType() : LineHeadType function set_startHeadType(value : LineHeadType)

ASP.NET Ajax Javascript (Usage)
var resultVar = instanceOfMark.get_startHeadType();

Example

This JavaScript code will create the mark shown in the image on this page.

// Create a new line mark. var mark = new ImageGear.Web.UI.Mark(ImageGear.Web.UI.MarkType.Line); // Set various properties. var points = mark.get_points(); points.setPoint(0, new ImageGear.Web.UI.Point(75, 175)); points.setPoint(1, new ImageGear.Web.UI.Point(175, 100)); mark.set_headFillColor('#7070ff'); mark.set_startHeadAngle(45); mark.set_startHeadLength(10); mark.set_startHeadType(ImageGear.Web.UI.LineHeadType.Solid); mark.set_lineWidth(3); // Add the mark to the page. // Adding them after setting the properties avoids a lot of needless markChanged events. $find('PageView1').get_artPage().addMark(mark); // Create a new line mark. // Note that if you skip this step, you will overwrite the properties of the original mark and the second call to addMark() will do nothing because the mark is already associated with the ArtPage. mark = new ImageGear.Web.UI.Mark(ImageGear.Web.UI.MarkType.Line); // Set various properties. points = mark.get_points(); points.setPoint(0, new ImageGear.Web.UI.Point(100, 200)); points.setPoint(1, new ImageGear.Web.UI.Point(200, 125)); mark.set_lineColor('#a0a0ff'); mark.set_endHeadAngle(30); mark.set_endHeadLength(25); mark.set_endHeadType(ImageGear.Web.UI.LineHeadType.Pointer); mark.set_startHeadAngle(10); mark.set_startHeadLength(35); mark.set_startHeadType(ImageGear.Web.UI.LineHeadType.PointerSolid); // Add the mark to the page. // Adding them after setting the properties avoids a lot of needless markChanged events. $find('PageView1').get_artPage().addMark(mark);
