L_LVKRN_API L_INT L_VecCopyGroup(pVectorDst, pGroupDst, pVectorSrc, pGroupSrc, dwFlags)
Copies the contents of one group to another. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
Pointer to the destination vector handle.
Pointer to a VECTORGROUP structure that references the destination group.
Pointer to the source vector handle.
Pointer to a VECTORGROUP structure that references the source group.
Flag that indicates whether or not to empty the destination group before copying. Possible values are:
| Value | Meaning |
|---|---|
| 0 | Do not empty the destination group before copying. |
| VECTOR_FLAGS_REPLACE | Empty the destination group before copying. |
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
The destination group can be in the same vector handle as the source group, or it can be in a different vector handle.
Required DLLs and Libraries
This example will copy the group with the given name from the source vector to the destination vector.
