java - When reassigning color to pixels, all color is black -

-

simplified code:

public static void main(string[]args) throws exception {     bufferedimage img = new bufferedimage(512, 512, bufferedimage.type_int_argb);      (int = 0; < 512; i++) {         (int j = 0; j < 512; j++) {              if (complex.getinfinite()) {                 color newcol = new color(100, 0, 0);                 img.setrgb(i, j, newcol.getrgb());             }             if (complex.getinfinite() == false) {                 color newcol = new color(0, 0, 100);                 img.setrgb(i, j, newcol.getrgb());             }         }     }     saveimage(img, new file("julia.jpg")); }

my problem when run program, julia.jpg black image.
have played around amount of pixels color , pixels coloring turn black.

i wondering if issue when generated image gave wrong type.

change

bufferedimage img = new bufferedimage(512, 512, bufferedimage.type_int_argb);

to

bufferedimage img = new bufferedimage(512, 512, bufferedimage.type_int_bgr);

more details: bufferedimage.type_int_bgr
