Creating a custom DataBuffer for very LARGE images

Question

I would like to work with very large images (up to 100MB) in an application.
Only for image manipulating, not rendering for screen.
My idea is to write my own DataBuffer which use Hard Drive,maybe with some "intelligent" swapping.
But At first performance doesn�t matter.
I try this:ColorModel cm = ColorModel.getRGBdefault();
SampleModel sm = cm.createCompatibleSampleModel(w,h);
DataBuffer db =  new  myDataBufferInt(size);
WritableRaster raster = Raster.createWritableRaster(sm,db,null);But somebody don�t like myDataBuffer
and of course it is type DataBuffer.TYPE_INTthrows:java.awt.image.RasterFormatException: IntegerComponentRasters must haveinteger DataBuffers
at sun.awt.image.IntegerComponentRaster.<init>(IntegerComponentRaster.java:155)
at sun.awt.image.IntegerInterleavedRaster.<init>(IntegerInterleavedRaster.java:111)
at sun.awt.image.IntegerInterleavedRaster.<init>(IntegerInterleavedRaster.java:78)
at java.awt.image.Raster.createWritableRaster(Raster.java:980)
public  class myDataBufferInt extends DataBuffer {
public myDataBufferInt(int size) {
        super(TYPE_INT,size);
    . . . }The question is how to manage large image?
What kind of subclasses I have to write?
Thank you all
P.S: I don�t want to use: java -Xmsn -Xmxn
