L_VecAddGroup

#include "lvkrn.h"

L_INT EXT_FUNCTION L_VecAddGroup(pVector, pGroupDesc, pGroup, dwFlags)

pVECTORHANDLE pVector;

/* pointer to a vector handle */

const pVECTORGROUPDESC pGroupDesc;

/* pointer to a structure */

pVECTORGROUP pGroup;

/* pointer to a vector group */

L_UINT32 dwFlags;

/* flags */

Adds a new empty group to a vector handle. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameter

Description

pVector

Pointer to the vector handle.

pGroupDesc

Pointer to a VECTORGROUPDESC structure that contains the new group settings.

pGroup

Pointer to a VECTORGROUP structure to be updated with the handle of the new group.

dwFlags

Flag that indicates whether or not to rename duplicate group names. Possible values are:

 

Value

Meaning

 

0

Don't rename duplicate group names, if found.

 

VECTOR_FLAGS_RENAME_DUPLICATES

Renames duplicate group names if found. The toolkit will add a suffix (0, 1, 2, etc) to the group name if duplicated. Checking will be aborted when the suffix value reaches 999 and no unique name can be created.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

For more information on the group settings, refer to the VECTORGROUPDESC structure.

To change group settings, get the current group settings by calling L_VecGetGroup, set the new settings in the VECTORGROUPDESC structure pointed to by pGroupDesc and then set the new group settings by calling L_VecSetGroup.
