Hello,

I want to generate the JPEG2000 file from the tiff file which is
containing 20000 samples and 20000 lines, I am writing the following
code.

jp2filename = 'abc'
Data = read_tiff('c:\satellite.tif')
imageDims = Size(data,/Dimension)

; Prepare JPEG2000 object property values.
ncomponents = 3
nLayers = 20
nLevels = 6
offset = [0,0]
jp2TileDims = [1024, 1024]
jp2TileOffset = [0,0]
bitdepth = [8,8,8]

; Create the JPEG2000 image object.
oJP2File = OBJ_NEW('IDLffJPEG2000',jp2filename , WRITE=1)
oJP2File->SetProperty, N_COMPONENTS=nComponents, $
N_LAYERS=nLayers, $
N_LEVELS=nLevels, $
OFFSET=offset, $
TILE_DIMENSIONS=JP2TileDims, $
TILE_OFFSET=JP2TileOffset, $
BIT_DEPTH=bitDepth, $
DIMENSIONS=[imageDims[1],ImageDims[2]]

oJP2FILE->SetData, Data
OBJ_DESTROY, oJP2FILE

Now the problem is that IDL 6.2 is unable to allocate the memory for
storing the data.

Is there any other way to do this? If yes Then How one can do it?

Thanks In Advance.
