You don't set the width and height on the Image object, you tell Graphics the width and height that you want to draw them it:

int width = 100;
int height = 100;
g.drawImage((Image)lines.elementAt(k), x, y, width, height this);

You can use the ReplicateScaleFilter class.

It has a "setDimensions()" method and you can use it to set the new dimensions of your image.

See
