The LineCap enumeration specifies the type of graphic shape to use on the end of a line drawn with a Microsoft Windows GDI+ pen. The cap can be a square, circle, triangle, arrowhead, custom, or masked (hidden). End caps can also "anchor" the line by centering the cap at the end of the line.

常数

 

LineCapFlat

 

Specifies that the line ends at the last point. The end is squared off.

 

LineCapSquare

 

Specifies a square cap. The center of the square is the last point in the line. The height and width of the square are the line width.

 

LineCapRound

 

Specifies a circular cap. The center of the circle is the last point in the line. The diameter of the circle is the line width.

 

LineCapTriangle

 

Specifies a triangular cap. The base of the triangle is the last point in the line. The base of the triangle is the line width.

 

LineCapNoAnchor

 

Specifies that the line ends are not anchored.

 

LineCapSquareAnchor

 

Specifies that the line ends are anchored with a square. The center of the square is the last point in the line. The height and width of the square are the line width.

 

LineCapRoundAnchor

 

Specifies that the line ends are anchored with a circle. The center of the circle is at the last point in the line. The circle is wider than the line.

 

LineCapDiamondAnchor

 

Specifies that the line ends are anchored with a diamond (a square turned at 45 degrees). The center of the diamond is at the last point in the line. The diamond is wider than the line.

 

LineCapArrowAnchor

 

Specifies that the line ends are anchored with arrowheads. The arrowhead point is located at the last point in the line. The arrowhead is wider than the line.

 

LineCapCustom

 

Specifies that the line ends are made from a CustomLineCap.
