Chintan,

What are the dimensions of the image in your tiff file?

One thing you might try: write each tile individually. So, let's say
you have a 2048x2048 tiff file, and you want to write a jpeg2000 file
with tile dimensions of 1024x1024 (so there are four tiles), you could
do something like this:

oJP2FILE->SetData, Data[*,0:1023,0:1023],TILE_INDEX=0
oJP2FILE->SetData, Data[*,1024:2047,0:1023],TILE_INDEX=1
oJP2FILE->SetData, Data[*,0:1023,1024:2047],TILE_INDEX=2
oJP2FILE->SetData, Data[*,1024:2047],TILE_INDEX=3

You probably have larger tiff files, but this is the idea.

David
