Java based Image Scanning

use imageio class to get image

BufferedImage bi = ImageIO.read("url");

the bufferedImage class has method called getRGB

int tRGB[][] = new int[bi.width][bi.height];

for(int x=0;x<bi.width;++x){

for(int y =0;y<bi.height;++y){

tRGB[x][y] = bi.getRGB(x,y);

}

}

now tRGB[x][y] has the integer number repesented by binary combination of RGB

ie

binary 101010101000000011001010

to get three colors separated

use right shift

and AND it with ff;

int red = (tRGB[x][y]>>16)&0xff;

int green = (tRGB[x][y]>>8)&0xff;

int blue =tRGB[x][y]&0xff;

doing above process in loop u get three arrays of ntegers R G and B

now u can play with them as u wish.

there are processes faster than this one.

pls let me know if u come across any new.
