LJp2FileFormat::AppendGMLDataMemory

#include "ltwrappr.h"

L_INT LJp2FileFormat::AppendGMLDataMemory(pBuffer, uBufferSize, lpOutBuffer, puOutBufferSize, pGMLData)

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
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 LocalFree() 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

LJp2FileFormat::AppendGMLDataMemory 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.
