L_LTANN_API L_INT L_AnnGetPredefinedBitmap(uType, pBitmap, uStructSize)

L_UINT uType;	/* constant that indicates the bitmap to retrieve */
pBITMAPHANDLE pBitmap;	/* pointer to a variable to be updated with the bitmap handle */
L_UINT uStructSize;	/* size of the BITMAPHANDLE structure */

Retrieves a copy of the specified predefined bitmap.

Parameter	Description
uType	Value that indicates the bitmap to retrieve. Possible values are:
	Value	Meaning
	ANNBITMAP_POINT	[0] Predefined metafile for annotation point object
pBitmap	Pointer to a variable to be updated with the bitmap handle.
uStructSize	Size in bytes, of the structure pointed to by pBitmap, for versioning. Use sizeof(BITMAPHANDLE).

Returns

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

Comments

This function is valid only for the ANNOBJECT_POINT object. You must free the bitmap handle when you are finished, using L_FreeBitmap. Call the L_AnnSetPredefinedBitmap function to change or reset the predefined bitmap.

Example

This example does the following: 1. Gets the current point bitmap. 2. Inverts it. 3. Sets the inverted bitmap to be the default point bitmap.

 L_INT AnnGetPredefinedBitmapExample()
{
   BITMAPHANDLE PointBitmap;
   L_INT nRet = SUCCESS;
   // Get predefined point bitmap
   nRet = L_AnnGetPredefinedBitmap(ANNBITMAP_POINT, &PointBitmap, sizeof(BITMAPHANDLE));
   if(nRet != SUCCESS)
      return nRet;

   // Invert it
#if defined (LEADTOOLS_V16_OR_LATER)
   nRet = L_InvertBitmap(&PointBitmap, 0);
#else
   nRet = L_InvertBitmap(&PointBitmap);
#endif
   if(nRet != SUCCESS)
      return nRet;

   // Set as new point bitmap
   nRet = L_AnnSetPredefinedBitmap(ANNBITMAP_POINT, &PointBitmap);
   if(nRet != SUCCESS)
      return nRet;

   // Free the bitmap
   L_FreeBitmap(&PointBitmap);

   MessageBox(NULL, TEXT("Now create a point annotation object.  The bitmap is inverted"), TEXT(""), MB_OK);
   return SUCCESS;
}
