L_AnnSave

#include "l_bitmap.h"

L_LTANN_API L_INT L_AnnSave(pFile, hObject, uFormat, fSelected, pSaveOptions)

L_TCHAR * pFile;

name of the file to save

HANNOBJECT hObject;

handle to the root annotation

L_UINT uFormat;

file format for saving annotation data

L_BOOL fSelected;

flag that indicates which objects to save

pSAVEFILEOPTION pSaveOptions;

pointer to optional extended save options

Saves annotations in the specified file.

Parameter Description
pFile Character string containing the name of the file to save.
hObject Handle to the root annotation object that includes all objects to save in the file. This typically is a container object.
uFormat Format for saving annotation data. Possible values are:
  Value Meaning
  ANNFMT_EMF [0x0006] Use the Windows EMF format.
  ANNFMT_ENCODED [0x0004] Save as a binary format. NOTE: This format has been replaced by ANNFMT_XML, and is no longer supported
  ANNFMT_NATIVE [0x0000] Use LEAD's own format for annotations. NOTE: This format has been replaced by ANNFMT_XML, and is no longer supported.
  ANNFMT_WMF [0x0001] Use the Windows WMF format.
  ANNFMT_XML [0x0005] Save as an XML text format. This is LEADs new text based format which is upward compatible. It should be used instead of ANNFMT_NATIVE.
fSelected Flag that indicates which objects to save. 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. This information is used to add annotation pages or replace annotation pages in a multi-page annotation file. Pass NULL to save a one page annotation file.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

In version 15.0, the text based format ANNFMT_XML is replacing ANNFMT_NATIVE and ANNFMT_ENCODED.  Note that ANNFMT_NATIVE and ANNFMT_ENCODED are no longer supported as options with L_AnnSave, L_AnnSaveOffset, and L_AnnSaveMemory.

For backward compatibility, this latest version of LEADTOOLS can read the discontinued formats (ANNFMT_NATIVE and ANNFMT_ENCODED) with the following functions:

L_AnnLoad

L_AnnLoadOffset

L_AnnLoadMemory

L_AnnDeletePage

L_AnnDeletePageOffset

L_AnnDeletePageMemory

The ANNFMT_XML format offers many advantages over the older annotation formats:

Save annotations in the WMF format only for use in another application. LEADTOOLS reads annotations only in the native format.

To retain scaling and positioning information, this function always saves the root container, along with the specified object or selected objects. Use the hObject and fSelected parameters as follows:

The information in the SAVEFILEOPTION structure can be used to add new pages or replace existing pages in a multi-page annotation file of type ANNFMT_XML. Note that all the pages of an annotation multi-page file must be all of type ANNFMT_XML. An annotation file cannot contain pages of different format types.

To insert new pages to an annotation multi-page file:

1.

Declare a variable of type SAVEFILEOPTION.

2.

Set the uFlags field of the SAVEFILEOPTION structure to ESO_INSERTPAGE.

3.

Set the PageNumber field of the SAVEFILEOPTION structure to the location for insertion. The new page will be inserted in front of the page specified in the PageNumber field.

To replace an existing page in an annotation multi-page file:

1.

Declare a variable of type SAVEFILEOPTION.

2.

Set the uFlags field of the SAVEFILEOPTION structure to ESO_REPLACEPAGE.

3.

Set the PageNumber field of the SAVEFILEOPTION structure to the page to replace.

To delete a page from an annotation multi-page file, use L_AnnDeletePage, L_AnnDeletePageMemory, L_AnnDeletePageOffset.

Example

For another example, refer to L_AnnFileInfo. This example saves currently selected annotations in a file.

L_INT AnnSaveExample(HANNOBJECT hContainer)/* Container annotation object */ 
{ 
   L_INT nRet; 
 
   nRet = L_AnnSave(MAKE_IMAGE_PATH(TEXT("TEST.ANN")), hContainer, ANNFMT_XML, FALSE, NULL); 
   if (nRet == SUCCESS) 
      MessageBox(NULL, TEXT("Annotations saved"), TEXT("Notice"), MB_OK); 
   else 
      return nRet; 
   return SUCCESS; 
}
