Specifies all vector entities used by ImageGear.
Values:
| IG_VECT_ENT_UNKNOWN | Type of the entity is unknown. |
| IG_VECT_ENT_BLOCK | The entity is a block. A block contains a list of references to various entities. |
| IG_VECT_ENT_EASYLINE | The entity is an easy line (a line defined by two points). |
| IG_VECT_ENT_POLYLINE | The entity is a polyline. |
| IG_VECT_ENT_POLYLINEEX | The entity is an extended polyline (a polyline that may consist of several contours). |
| IG_VECT_ENT_ELLIPSE | The entity is a circle or an ellipse. |
| IG_VECT_ENT_ARC | The entity is a circular or elliptical arc. |
| IG_VECT_ENT_TEXT | The entity is a text. |
| IG_VECT_ENT_BEZIER_CURVE | The entity is a Bezier curve. |
| IG_VECT_ENT_NURBS_CURVE | The entity is a non-uniform rational Bi-spline curve. |
| IG_VECT_ENT_EASY_SURFACE | The entity is an easy surface defined by its mesh. |
| IG_VECT_ENT_NURBS_SURFACE | The entity is a non-uniform rational Bi-spline surface. |
| IG_VECT_ENT_FIGURE | The entity is a figure. A figure is a complex filled planar shape, defined by a list of regions, which, in turn, consist of entities. |
| IG_VECT_ENT_CONNECTION | The entity is a connection. It connects two consecutive entities in a figure. |
| IG_VECT_ENT_RASTER | The entity is a raster image. |
| IG_VECT_ENT_VIEWPORT | The entity is a viewport. |
| IG_VECT_ENT_BEZIER_SURFACE | The entity is a Bezier surface. |
| IG_VECT_ENT_SHELL | The entity is a shell. |
| IG_VECT_ENT_SHELLEX | The entity is an extended shell. |
| IG_VECT_ENT_SOLID | The entity is a planar quadrilateral defined by its four corners (corresponds to the "Solid" object of DWG and DXF formats). |
| IG_VECT_ENT_INSERTION | The entity is an insertion. It adds a reference to IG_VECT_ENT_BLOCK entity to a view content. It can specify a transformation and other attributes. One block can be referenced by several insertions. |
| IG_VECT_ENT_GEOMETRY | The entity is a geometry. It is an object consisting of primitives. One geometry can only contain primitives of one type. See enumIGVectGeometryType for the list of primitives supported by ImageGear. |
