Alright...so now I've changed my ImageUtils.java file (code is below)
and I'm getting a bunch of "cannot resolve symbol" errors when trying to
compile it. What am I missing now??
Thanks again...chris

public void load(String file) throws IOException

{

float modifier = edgeLength / (float) (tall ? height : width);
ParameterBlock params = new ParameterBlock();
params.addSource(image);
params.add(modifier);//x scale factor
params.add(modifier);//y scale factor
params.add(0.0F);//x translate

result = JAI.create("scale", params);
}
public void crop(float edge)
{
ParameterBlock params = new ParameterBlock();
params.addSource(image);
params.add(edge);//x origin
params.add(edge);//y origin
params.add((float) width - edge);//width
params.add((float) height - edge);//height
result = JAI.create("crop", params);

public void border(int edge, double edgeColor)
{
ParameterBlock params = new ParameterBlock();
params.addSource(image);
params.add(edge);//left pad

double fill[] = {edgeColor};
params.add(new BorderExtenderConstant(fill));//type
params.add(edgeColor);//fill color
result = JAI.create("border", params);
}
