Hey, this is the problem:
Supose you have done a random paint on your component, for example you are drawing a fractal that evolves with respect to many parameters like a response to an internet service. How can I get this image. I know how to encode an image for save it, I just want to know how get an already drawed one.
It could be as simple as this:
BufferedImage image = new BufferedImage(comp.getWidth(), comp.getHeight(), BufferedImage.TYPE_INT_RGB);
Graphics2D g = image.createGraphics();
comp.paint(g);
g.dispose();
ImageIO.write(image, "jpeg", new File("temp.jpeg"));
Ehh... the problem with component.paint(my_g) is that the component don't have the information for redraw it, because the image was generated randomly. With Alt+PrintScreen is a good aproach but I prefer doi it programatically, I need it.
However, thank you so much, I will add 7 stars to this post :D
Thanks!!!!!!!!
