L_LTJP2_API L_INT EXT_FUNCTION L_Jp2AppendGMLDataMemory(hJp2, pBuffer, uBufferSize, lpOutBuffer, puOutBufferSize, pGMLData)

L_HJP2 hJp2;

JPEG 2000 engine handle

L_UINT8 * pBuffer;

pointer to a JPEG 2000 file in memory

L_SIZE_T uBufferSize;

size of the JPEG 2000 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 in memory.  

Parameter

Description

hJp2

JPEG 2000 engine handle that was created by the L_Jp2Create function.

pBuffer

Pointer to a JPEG 2000 file in memory.

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_Jp2AppendGMLDataMemory appends GML data to the specified JPEG 2000 part 2 (JPX) file format in memory. If the file is JPX format, the functions returns: ERROR_FILE_FORMAT.

L_INT Jp2AppendGMLDataMemoryExample(L_UINT8* pFileBuffer, L_SIZE_T uFileSize, L_UINT8** lpOutBuffer, L_SIZE_T * puOutSize, pL_JP2_GMLDATA pGMLData) 
{ 
   L_HJP2 hEngine; 
 
   /*Create JPEG  2000 engine handle*/ 
   hEngine = L_Jp2Create(); 
 
   /*Read GML data*/ 
   L_Jp2AppendGMLDataMemory(hEngine, pFileBuffer, uFileSize, lpOutBuffer, puOutSize, pGMLData); 
 
   /*Destroy engine handle*/ 
   L_Jp2Destroy(hEngine); 
   return SUCCESS;
