L_AnnSaveTag

#include "l_bitmap.h"

L_LTANN_API L_INT L_AnnSaveTag(hObject, uFormat, fSelected)

HANNOBJECT hObject;	handle of the root annotation object
L_UINT uFormat;	file format for saving annotation data
L_BOOL fSelected;	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
hObject	Handle to the root annotation object.
uFormat	File format to use when saving the 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.
fSelected	Flag that indicates which objects to save. Possible values are:
	Value	Meaning
	TRUE	Save all selected objects.
	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. This function is the equivalent of the following:

HGLOBAL hMem;   
L_UINT32 ulSize;   
// save the annotations to memory   
L_AnnSaveMemory(hObject, uFormat, fSelected, &hMem &ulSize);   
// store a copy of the annotations in LTFIL   
L_SetTag(ANNTAG_TIFF, TAG_BYTE, ulSize, GlobalLock(hMem));   
// free the memory handle, since LTFIL has a copy   
GlobalUnlock(hMem);   
GlobalFree(hMem);

The annotations will not be saved unless you also save an image in one of the TIFF formats (FILE_TIF_JPEG, 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, FILE_TIF_CMP, FILE_TIF_JBIG).

This tag can be cleared using L_SetTag like this:

L_SetTag(ANNTAG_TIFF, 0, 0, NULL);

Example

This example saves all annotations in a container in a Wang compatible TIFF tag. The page and annotations are appended to the end of the file. Note that saving the annotation, as ANNFMT_WANGTAG will lose some objects/properties not supported by the Wang specification. If don't want to lose any information, save the annotations as ANNFMT_TIFFTAG instead.

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName 
L_INT AnnSaveTagExample(pBITMAPHANDLE pBitmap, HANNOBJECT hContainer) /* Container object */ 
{ 
   L_INT nRet; 
   SAVEFILEOPTION SaveFileOption; 
   nRet = L_GetDefaultSaveFileOption(&SaveFileOption, sizeof(SAVEFILEOPTION)); 
   if(nRet != SUCCESS) 
      return nRet; 
   SaveFileOption.PageNumber = 2; // append the page 
   /* set Wang Compatibility mode for annotations */ 
   nRet = L_AnnSaveTag(hContainer, ANNFMT_WANGTAG, TRUE); 
   if(nRet != SUCCESS) 
   { 
      MessageBox(NULL, TEXT("Error creating annotation data.\n") 
      TEXT("The file will be saved without annotations.\n\n"), 
      TEXT("Annotation Error"), 
      MB_OK); 
      return nRet; 
   } 
   /* Save the bitmap to a file, with the tag. */ 
   nRet = L_SaveBitmap(MAKE_IMAGE_PATH(TEXT("Result.TIF")),pBitmap, FILE_TIF, 0, 0, &SaveFileOption); 
   if(nRet != SUCCESS) 
      return nRet; 
   return SUCCESS; 
}
