Question

hi im trying to draw a picture on my panel with a fct name JP. TRaht work eprfectly, but i want the size of the Image (name ball) because now im adding my picture with the size 200,200, but its to big, and the picture could change each time the suer run the application, so maybe its easy, but i want to find the size of the picture, he have no fct getWidth or variable width for the image!!! i want height too.
i get the picture from a paramater taht i pass to my applet..

try
    paramCheminImage = getParameter("cheminImage");
    URL url = new URL(paramCheminImage);
    ball = Toolkit.getDefaultToolkit().createImage(url);
    dessin.add(new JP(8, 0, 0, 200, 200), 0);
    image = true;
    repaint();
catch(Exception e)
    System.out.println(e.getMessage());
}

Answer 1

oups sorry i forgot some times taht my code is clear for me, and not for other taht doesnt see my program
paramCheminImage is the url where my image is
i get it from a parametr i pass in my applet (cheminImage)
ball is my image taht i create with the url i got from the paramater
after i use a fct that the image to component that to my frame dessin
8 is the type of adding (use in my fct), 0 is the x, 0 is the y, and 200,200 is width and height
image is a boolean i sue in my fct JP
and i repaint to see the change
all this work perfectly, but i want at place of 200,200, the real size of the image i had recuperate from the url
wish that explain you my program
thx
