L_LVKRN_API L_INT L_VecAddObjectToGroup(pVector, pGroup, nType, pObjectDesc, pNewObject)
Adds a new object to a vector group. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
Pointer to the destination vector handle.
Pointer to the destination vector group.
Type of object to add. Possible values are:
| Value | Meaning |
|---|---|
| VECTOR_ARC | Arc. |
| VECTOR_CHORD | Chord. |
| VECTOR_CIRCLE | Circle. |
| VECTOR_ELLIPSE | Ellipse. |
| VECTOR_ELLIPTICALARC | Elliptical arc. |
| VECTOR_LINE | Line. |
| VECTOR_PIE | Pie section. |
| VECTOR_POLYBEZIER | Poly Bezier curve. |
| VECTOR_POLYDRAW | Polydraw. |
| VECTOR_POLYGON | Polygon. |
| VECTOR_POLYLINE | Polyline. |
| VECTOR_RASTER | Raster. |
| VECTOR_RECTANGLE | Rectangle. |
| VECTOR_TEXT | Text. |
| VECTOR_VERTEX | 3D vertex in space. |
Pointer to a vector object that contains information about the object to add.
Pointer to a VECTOROBJECT structure that references the newly added object.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
If pNewObject is NULL, this pointer will not be updated with the address of the newly added object.
You may need to cast from your given object type (VECTORPOLYGON, VECTORTEXT, etc) when using this function. (See the example below.)
You cannot add a VECTOR_CLONE to a vector group.
Required DLLs and Libraries
This example will create a new vector group with the given name that contains all currently selected objects inside a vector handle.
