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.
