LAnnContainer::SaveTag

#include "ltwrappr.h"

virtual L_INT LAnnContainer::SaveTag(uFormat=ANNFMT_TIFFTAG, bSelected=FALSE)

L_UINT uFormat;	format for saving annotation data
L_BOOL bSelected;	flag that indicates which objects to save

Copies the annotation objects into a memory location so that the next TIFF saved will contain these annotations in a Wang compatible TIFF tag.

Parameter	Description
uFormat	Format for saving annotation data. Possible values are:
	Value	Meaning
	ANNFMT_TIFFTAG	[0x0002] Save the object in WANG format, along with all LEAD properties not supported by the Wang specification.
	ANNFMT_WANGTAG	[0x0003] Save only the properties supported by the Wang specification.
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.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

After calling this function, saving an image as a TIFF format will cause the annotations to be saved in a tag in the TIFF file.

The annotations will not be saved unless you also save an image in one of the TIFF formats (FILE_TIF_JPEG, FILE_TIF_JPEG_411, FILE_TIF_JPEG_422, FILE_CCITT, FILE_TIF, FILE_TIFLZW, FILE_CCITT_GROUP3_1DIM, FILE_CCITT_GROUP3_2DIM, FILE_CCITT_GROUP4, FILE_TIF_CMYK, FILE_TIFLZW_CMYK, FILE_TIF_PACKBITS, FILE_TIF_PACKBITS_CMYK, FILE_TIF_YYC, FILE_TIFLZW_YYC, FILE_TIF_PACKBITS_YCC).

This tag can be cleared using LFileSettings::SetTag.
