Question

What is the right way to convert raw array of bytes into Image in Java SE.
array consist of bytes, where each three bytes represent one pixel, with each byte for corresponding RGB component.

Can anybody suggest a code sample?

Thanks,
Mike

Assuming you know the height and width of the image.

BufferedImage img=new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
for(int r=0; r<height; r++)
for(int c=0; c<width; c++)
{
  int index=r*width+c;
  int red=colors[index] & 0xFF;
  int green=colors[index+1] & 0xFF;
  int blue=colors[index+2] & 0xFF;
  int rgb = (red << 16) | (green << 8) | blue;
  img.setRGB(c, r, rgb);
}

Roughly. This assumes the pixel data is encoded as a set of rows; and that the length of colors is 3 * width * height (which should be valid).
