LAnnContainer::SaveTag

Summary

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

Syntax

#include "ltwrappr.h"

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

Parameters

L_UINT 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.

L_BOOL 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

Value	Meaning
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.
