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.
