L_LTJP2_API L_INT EXT_FUNCTION L_Jp2AppendBoxes(hJp2, pszFile, uBoxType, pBoxes, uNumOfBoxes)

L_HJP2 hJp2;	JPEG 2000 engine handle
L_TCHAR * pszFile;	name of the file
eJP2BOXTYPE uBoxType;	box type
L_VOID * pBoxes;	pointer to an array of boxes
L_UINT uNumOfBoxes;	number of boxes

Appends boxes of uBoxType to the specified file.

Parameter	Description
hJp2	JPEG 2000 engine handle that was created by the L_Jp2Create function.
pszFile	Character string that contains the name of the file to append boxes.
uBoxType	The type of the boxes to be appended.
pBoxes	Point to an array of boxes of type uBoxType.
uNumOfBoxes	Number of boxes in the array.

Returns

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

Comments

This function appends JPEG 2000 boxes to the specified file. If the specified box type is L_JP2_IPR, L_JPX_IPR, L_JPX_GTSO, or L_JPX_COMPOSITION, only the first box will be appended, because a JPEG 2000 file cannot have more than one box each of these types. Boxes of type uBoxType will be reset and updated with the new appended boxes only.

This function does not append L_JP2_RESOLUTION_BOX box it returns ERROR_INV_PARAMETER error, this box can be set by L_Jp2SetBoxes.

Example

This example appends a box to already existing JPEG 2000 file.

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName 
L_INT Jp2AppendBoxesExample(L_UINT8 * pXMLData, L_SIZE_T uSize) 
{ 
   L_HJP2 hEngine; 
   L_INT  nRet; 
   L_JP2_XML_BOX XMLBox; 
   /*Create JPEG  2000 engine handle*/ 
   hEngine = L_Jp2Create(); 
   /*Create an XML box*/ 
   XMLBox.uStructSize = sizeof(L_JP2_XML_BOX); 
   XMLBox.pData = pXMLData; 
   XMLBox.uDataSize = uSize; 
   /*Append XML box to a JPX file*/ 
   nRet = L_Jp2AppendBoxes(hEngine,MAKE_IMAGE_PATH(TEXT("image1.jp2")), L_JP2B_XML,&XMLBox,1); 
   if(nRet != SUCCESS) 
      return nRet; 
   /*Destroy engine handle*/ 
   L_Jp2Destroy(hEngine); 
   return SUCCESS;
