Creating an Image of a invisible component
Hi, i know how to create a Image from a JComponent or anything that have a paint function. It create my Image with no problem. But now i have to create a Image Object of a JComponent that the user won't have to see. I set my Component to setVisible(false) and when i create the Image, my Image Object is null but if i setVisible(true) and i do the Image it's ok. So my question: "is there a way to create an Image Object from a Component that are not visible?"
i use this code to create the Image Object
Rectangle rect = table.getBounds();
Image ima = createImage(rect.width, rect.height);
Graphics2D g = (Graphics2D) ima.getGraphics();
table.paint(g);
g.dispose();
thx

You could only save an image of something when it's visible, so you'd have to show it then hide it.

hummm it's not really usefull.... cause i do my picture when a bi things is loading, so the user have the time to see the component visible, and i cant do my image elsewhere...
i was thinking that somebody could have a solution for that :(
thx
