mitab中写生成TAB文件，画扇区形状如何写？

public enum FeatureType {
        TABFC_NoGeom = 0,
        TABFC_Point = 1,
        TABFC_FontPoint = 2,
        TABFC_CustomPoint = 3,
        TABFC_Text = 4,
        TABFC_Polyline = 5,
        TABFC_Arc = 6,
        TABFC_Region = 7,
        TABFC_Rectangle = 8,
        TABFC_Ellipse = 9,
        TABFC_MultiPoint = 10};

FeatureType用哪个可以写出来扇区形状，实在想不到怎么写了，给个思路
