LAnnContainer::Save

#include "ltwrappr.h"

virtual L_INT LAnnContainer::Save(pFile, uFormat=ANNFMT_NATIVE, bSelected=TRUE, pSaveOptions=NULL)

L_TCHAR * pFile;	/* name of the file to save */
L_UINT uFormat;	/* format for saving annotation data */
L_BOOL bSelected;	/* 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.
uFormat	Format for saving annotation data. Possible values are:
	Value	Meaning
	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 NOTE: This format has been replaced by ANNFMT_XML, and is no longer supported.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] Save the file in the Windows WMF format.
	ANNFMT_ENCODED	[0x0004] Save as a binary format NOTE: This format has been replaced by ANNFMT_XML, and is no longer supported
	ANNFMT_XML	[0x0005] Save the file in an XML text format. This is LEADs new text-based format which is upward-compatible. It should be used instead of ANNFMT_NATIVE. This is the default value.
bSelected	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 LAnnotation::IsSelected and LAnnotation::SetSelected 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 LAnnContainer::Save, LAnnContainer::SaveOffset, and LAnnContainer::SaveMemory.

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

LAnnContainer::Load

LAnnContainer::LoadOffset

LAnnContainer::LoadMemory

LAnnContainer::DeletePage

LAnnContainer::DeletePageOffset

LAnnContainer::DeletePageMemory

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

To save only selected objects in a container, set bSelected to TRUE.
To save all objects in a container, set bSelected to FALSE.

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 LAnnContainer::DeletePage, LAnnContainer::DeletePageMemory, or LAnnContainer::DeletePageOffset.
