Opening a single image from a tiff stack

Hi,

I am trying to write a plugin which needs to read in single frames from
a TIFF stack. It appears that a virtual stack is the way to go so I tried:

TiffDecoder td = new TiffDecoder(directory, filename);
FileInfo[] fi = td.getTiffInfo();
FileInfoVirtualStack vs = new FileInfoVirtualStack(fi[0]);
ImageProcessor ip = vs.getProcessor(frame);

This works but has the unwanted side effect of displaying the stack too.
I had a look at the source code and the open() method in
FileInfoVirtualStack ends with imp2.show();
Is there another way of obtaining single images from a stack (without
having to load in the entire stack or display anything unwanted on
screen)? In the meantime I have subclassed FileInfoVirtualStack and
replaced the open() method with an identical copy, apart from the
unwanted imp2.show(); command.

Thanks,
Mike.
