Please specify what you mean by scaling. I am not sure what you mean. Do you want to add more elements to matrix or do you want to scale matrix in mathematical terms?Tuukka

Image has method getScaledInstance that can be used to scale images. Could you use this to accomplish what you are trying to do?

Image img = createImage(new MemoryImageSource(w, h, pix, 0, w))

w - the width of the rectangle of pixels

h - the height of the rectangle of pixels

pix - an array of pixels

off - the offset into the array of where to store the first pixel

scan - the distance from one row of pixels to the next in the array

More info can be found at: http://java.sun.com/j2se/1.4/docs/api/java/awt/image/MemoryImageSource.html

hope this helps you
