Converting an Image to a PlanarImage

Question

I have captured a frame from a video clip as an Image, and want to send this through a series of filters I have programmed.
These filters use JAI and so take PlanarImages as inputs.
I therefore wouldlike to convert an Image to a PlanarImage. Any suggests would be much appreciated.
Also I before I send my Image through the filtering, I want to split the RGB image into 3 gray_scale images (one for each band). I am also struggling with this.
I can get the A,R,G,B of the image easily enough, but I don't know how to transform these into seperate Images or PlanarImages.
Cheers,
Adam

Answer 1

The following should do it
Image src = BufferToImage.createImage(WHATEVER);
RenderedOp result = JAI.create("AWTImage",src);RenderedOp is a PlanarImage and also implements RenderedImage.
I would split the image into colour bands after you get it into the
JAI domain. There is a simple operation to do it.
public RenderedOp getBand(RenderdOp src, int band) {
  int[] bands = new int[1];
  bands[0] = band; // select band
  ParameterBlockJAI param = new ParamterBlockJAI("BandSelect");
  param.addSource(src);
  param.add("bandIndices", bands);
  return JAI.create("BandSelect",param);
