TIELineLayer.StartShape

Declaration

property StartShape: TIELineEndShape;

Description

Specifies the shape that is displayed at the start of the line.

Note:
◼ The border width and color of the arrow will be the same as the line (i.e. specified by LineColor and LineWidth)
◼ The fill is specified by FillColor (Gradients are not supported)
◼ If a label is displayed and LabelPosition= ielpAtStart, then the StartShape will not be shown

Default: ieesNone

Examples

// Add yellow filled arrows and circle ends to our current line layer

ImageEnView1.Update();

// Add a curved arrow line layer

ImageEnView1.Update();

// Add a ruler layer showing lengths in MM
