L_LTANN_API L_INT L_AnnSaveMulti(pFile, phObjects, nCount, uFormat, fSelected, pSaveOptions)

L_TCHAR * pFile;

name of the file to save

HANNOBJECT *phObjects;

pointer to an array of annotation container handles

L_INT nCount;

the number of objects in the phObjects array

L_UINT uFormat;

file format for saving annotation data

L_BOOL fSelected;

flag that indicates which objects to save


pointer to optional extended save options

Saves an array of annotation containers to the specified file.

Parameter Description
pFile Character string that contains the name of the file to save.
phObjects Pointer to an array of handles to annotation container objects.  Each annotation container object can include multiple annotation objects.
nCount The number of objects in the phObjects array. 
uFormat Format for saving annotation data. Possible values are:
  Value Meaning
  ANNFMT_XML [0x0005] Save as an XML text format. This is the only format supported for this call.  All other values return ERROR_FEATURE_NOT_SUPPORTED.
fSelected Flag that indicates which objects to saved. Possible values are:
  Value Meaning
  TRUE Save all objects that have the selected property set to TRUE. For getting and setting the selected property, use the L_AnnGetSelected and L_AnnSetSelected functions.
  FALSE Save only the specified object.
pSaveOptions Pointer to a SAVEFILEOPTION structure that contains optional extended save options.  Pass NULL because this parameter is currently ignored.



The function was successful.

< 1

An error occurred. Refer to Return Codes.


This function saves an entire array of annotation container objects with each page of the multi-page annotation file corresponding to one of the annotation containers. If pFile already exists, it will be overwritten.  If phObjects  contains many annotation containers, then this function will create the multi-page annotation file much faster than repeated calls to L_AnnSave.  Note that this function only supports the ANNFMT_XML format.  Passing any other format for uFormat will return an ERROR_FEATURE_NOT_SUPPORTED error.

This example creates an annotation container with two objects, saves ten copies of the container in a multipage annotation file, and then reloads the ten containers from the file.
