#include "ltwrappr.h"

L_INT LJp2FileFormat::AppendBoxesMemory(pBuffer, uBufferSize, lpOutBuffer, puOutBufferSize, uBoxType, pBoxes, uNumOfBoxes)

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

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 file in buffer.

Parameter

Description

pBuffer

Pointer to a JPEG 2000 file in the 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 boxes. 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.

uBoxType

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.
