Buffered image set RGB doesnt work - JAVA -


i have following problem: work image in java. set color pixels , save image. if load image program. pixels having different color ! code:

bufferedimage img = loadimage(); . . //new image drawing bufferedimage newimg = new bufferedimage(img.getwidth(), img.getheight(),                 bufferedimage.type_int_rgb); graphics2d g2 = (graphics2d) newimg.getgraphics();  //get pixel color int pixel = img.getrgb(0, 0);  //parsing color int red = (pixel >> 16) & 0xff; int green = (pixel >> 8) & 0xff; int blue = (pixel) & 0xff;  //real drawing g2.setcolor(new color(red, green, blue));             g2.drawline(0, 0, 0, 0); // color r: 55, g: 54 b: 53  //saving  imageio.write(newimg, "jpg", outputfile);

after this, run program can read pixel color..

the commands same..

if check color of new image, rgb are: r 52, g: 48 b: 81.

i set r: 55, g: 53, b:53 , r 52, g: 48 b: 81

where can problem?

thank advice.

this because of jpeg type

jpeg values doesn't save discretely jpeg save rgb values of picture function.

instead of using jpeg use png format , see setrgb() works exactly.

so replace code below 

imageio.write(image, "png", outputfile);
