Hello,
The general idea is:
BufferedImage destinationImg = ...
MapContent myMap = ...
// calculate bounds for your desired origin and scale
ReferencedEnvelope paintArea = ...
StreamingRenderer renderer = new StreamingRenderer();
renderer.setMapContent(myMap);
Graphics2D gr = destinationImg.createGraphics();
Rectangle rect = new Rectangle(
destinationImg.getMinX(), destinationImg.getMinY(),
destinationImg.getWidth(), destinationImg.getHeight());
renderer.paint(gr, rect, paintArea);
Please see the javadocs for more info about the above classes.
Hope this helps,
Michael
