LAnnContainer::Save

#include "ltwrappr.h"

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

L_TCHAR L_FAR * 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. This function is available in the Document/Medical Toolkits.

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] Save the file in the native format for LEAD annotations. NOTE: This format is being replaced by ANNFMT_XML.
	ANNFMT_WMF	[0x0001] Save the file in the Windows WMF format.
	ANNFMT_ENCODED	[0x0004] Save the file in a binary format. This file size is smaller and is upward compatible. It also provides better security.
	ANNFMT_XML	[0x0005] Save the file in an XML text format. This is LEAD’s new text-based format which is upward-compatible. It should be used instead of ANNFMT_NATIVE.
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 14.5, the text-based format ANNFMT_XML is being introduced. It has many advantages over ANNFMT_NATIVE and ANNFMT_ENCODED including:

$image\sqrblit.gif$ It is both forward- and backward-compatible.

$image\sqrblit.gif$ It is human readable.

$image\sqrblit.gif$ It can be easily modified using a standard text editor (i.e. notepad.exe).

$image\sqrblit.gif$ It can be easily parsed using any standard XML parser.

$image\sqrblit.gif$ It can be used with any of the growing number of utilities that work with XML.

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

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

$image\sqrblit.gif$ To save only selected objects in a container, set bSelected to TRUE.

$image\sqrblit.gif$ 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_NATIVE, ANNFMT_ENCODED or ANNFMT_XML. Note that all the pages of an annotation multi-page file must be all of type ANNFMT_NATIVE or all of type ANNFMT_ENCODED or 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.
