L_LVKRN_API L_INT L_VecCopyGroup(pVectorDst, pGroupDst, pVectorSrc, pGroupSrc, dwFlags)
pVECTORHANDLE pVectorDst; |
/* pointer to a vector handle */ |
const pVECTORGROUP pGroupDst; |
/* pointer to a group */ |
const pVECTORHANDLE pVectorSrc; |
/* pointer to a vector handle */ |
const pVECTORGROUP pGroupSrc; |

L_UINT32 dwFlags; |
/* copy flags */ |
Copies the contents of one group to another. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.
Parameter |
Description |
|
pVectorDst |
Pointer to the destination vector handle. |
|
pGroupDst |
Pointer to a VECTORGROUP structure that references the destination group. |
|
pVectorSrc |
Pointer to the source vector handle. |
|
pGroupSrc |
Pointer to a VECTORGROUP structure that references the source group. |
|
dwFlags |
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. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The destination group can be in the same vector handle as the source group, or it can be in a different vector handle.

Example
This example will copy the group with the given name from the source vector to the destination vector.
