Panning problem...

[Janice Tan <ta...@gmail.com>]

hi,

i realised that when i pan on a transparent background
(canvas.setBackground(new
Color (0,0,0,0)))the canvas seems to redraw over each other while moving
thus leaving a trail like effect. is there a way that i can pan it neatly
and cleanly while having a transparent background.

also, is it possible to clear the canvas that is on the frame of its
contents before another SVG is drawn on it?

thanks!

    How are you panning?  Also did you notify Swing that the canvas 
was transparent (JComponent.setOpaque(false))?

    I don't fully follow the question but I suspect the answer is the
same it's the same as above...
