L_LTJP2_API L_INT EXT_FUNCTION L_Jp2AppendGMLData(hJp2, pFileName, lpOutBuffer, puOutBufferSize, pGMLData)

L_HJP2 hJp2;	/* JPEG 2000 engine handle*/
L_TCHAR * pFileName;	/* name of the file */
L_UINT8 ** lpOutBuffer;	/* pointer to a pointer */
L_SIZE_T * puOutBufferSize;	/* pointer to a variable to be updated */
pL_JP2_GMLDATA pGMLData;	/* pointer to the L_JP2_GMLDATA structure */

Appends GML data to the specified JPEG 2000 part 2 (JPX) file format.

Parameter	Description
hJp2	JPEG 2000 engine handle that was created by the L_Jp2Create function.
pFileName	Character string that contains the name of the JPEG 2000 file to append the GML data.
uBufferSize	Size of the JPEG 2000 file in bytes.
lpOutBuffer	Pointer to a pointer to be updated with an array of bytes that contains a JPEG 2000 file with new appended GML data. You must free this buffer by calling the Windows GlobalFree () function.
puOutBufferSize	Address of a variable to be updated with the size of the output memory buffer in bytes.
pGMLData	Pointer to the L_JP2_GMLDATA structure that has the GML data to be appended.

Returns

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

Comments

L_Jp2AppendGMLData appends GML data to the specified JPEG 2000 part 2 (JPX) file format. If the file is JPX format, the function returns: ERROR_FILE_FORMAT.

Example

This example appends user GML data to a JPEG 2000 file.

L_LTJP2TEX_API L_INT Jp2AppendGMLDataExample(pL_JP2_GMLDATA pGMLData)
{
   L_HJP2 hEngine;

   /*Create JPEG  2000 engine handle*/
   hEngine = L_Jp2Create();

   /*Read GML data*/
   L_Jp2AppendGMLData(hEngine, TEXT("%UserProfile%\\My Documents\\LEADTOOLS Images\\image1.jpx"), pGMLData);

   /*Destroy engine handle*/
   L_Jp2Destroy(hEngine);
   return SUCCESS;
