Adds a new object to a vector layer. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
Parameter |
Description |
|
pVector |
Pointer to the destination vector handle. |
|
pLayer |
Pointer to the destination vector layer. |
|
nType |
Type of object to add. Possible values are: |
|
|
Value |
Meaning |
|
VECTOR_ARC |
Arc. |
|
VECTOR_CHORD |
Chord. |
|
VECTOR_CIRCLE |
Circle. |
|
VECTOR_CLONE |
Clone object of a vector group. |
|
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_STOCK |
Stock object from a stock library. |
|
VECTOR_TEXT |
Text. |
|
VECTOR_VERTEX |
3D vertex in space. |
pObjectDesc |
Pointer to a vector object that contains information about the object to add. |
|
pNewObject |
Pointer to a VECTOROBJECT structure that references the newly added object. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
If pLayer is NULL, the object will be added to the current active layer within the vector handle.
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.)

Example
This example will add a new red line from 1.0, 1.0, 0.0 to 2.0, 2.0, 0.0 to the vector handle.
