#3270 — Graphics2D question.

  To: comp.lang.java.gui
Hello,

I want to build my application from three main classes.
1. A frame class to handle file operations.
2. A Drawing panel to render images to.
3. An engine to perform the actual rendering.

All the examples I have read so far for Image stuff in Java have 
everything stuffed into one monolithic class, and the crux of the 
rendering seems to be done in paint(Graphics g) or 
paintComponent(Graphics g) using a g2d object cast againg the parameter g.

If I wanted to do calculations for rotations translations etc I can do 
this with the AffineTransform class setX methods, but the drawImage 
method of g2d seems to be handled in the paint/paintComponent methods.

This is fine until I want to specify x, y arguments in the drawImage 
Method as neither Paint or PaintComponent take these parameters in their 
method signature how can I do this, is there another way to draw apart 
from the paint/paint component methods?

Any help appreciated.
